small sailing yacht
I built this one for my grandaughter. She is from a MB free plan about 12 inches long that used to have a swing rig. I don't like swing rigs so set up a very simple sail set from ripstop nylon material.
The sails are just hot cut so no sewing needed.
The vane steering works very well and on a small pond keeps you very fit!
Again no radio but a lot of fun for a young person.
Susie says "Not seen this one before"! You are not old enough puss.

Anglian Trawler
I have been doing a bit of re-furbishing and this is the Very old Hobby's kit for The Anglian Trawler, about 18 inches long. The all balsa kit is from the late 1950s. The kit was complete, note the cast lines in the just visible lead weights, these came ready shaped!
The Mighty Midget electric motor does its bit to give her a healthy turn of speed running on a discarded Sony movie camera 6 volt battery.
No radio and only for small ponds. I have kept her as was, this is Susie, Just checking!

Celia May
This is one of those toy boats that I used to look at through the Basset-lowke window in Holborn. Not an original Bowman Sea Jay but a copy I made from the Basil Harley plans of Celia May 1988.
I suppose I started in 1989 almost certainly a Sunday as I had to hunt round to find some 3/8ths" thickness wood. The only stuff I could find was some 9 ply which is quite tough.
So I made a steam cylinder from plastic guttering tubing. I boiled an old fashioned kettle into it and about 5 minutes of this softened the ply for bending. I made a crude former, mainly big nails, and whipped it out and bent the ply to shape. Then the other one followed and the hard bit had been done.
The rest of the hull was straight forward. The superstructure was made of aluminium, not easy to bend but a friend showed me how.
The boat was meant to have a steam plant but the one I had built by an excellent engineer for me was in the end too heavy. So I left the boat for a few months and then decided to go electric.
If you look at the plans the 3 parts of the s/s are individual and have another bend also to form the deck, great for steam not so for electric. I cut the flanges off and made a wood deck and planked it to look pretty, well it is a toy after all, and fitted the s/s parts into the deck.
Those ex-Meccano gents will spot the rudder parts a 2 inch pulley which I carefully sawed to make the 2 parts. These have a wrap round chain and a small spring to tension the chain. The rudder servo has a small extension and the whole has worked with a little oil ever since.
The motor is a Bassett-lowke Marine bought when I was in my teens but not really used.
The yellow U/J is I think from SHG it has a loose "bone" as the connection between the 2 ends. It allows for a lot of positioning of the motor as I had planned to use the boat as a test vessel.
Notes The cat is Suzie my little helper and is 13 now.
I really like the funnel, it is rolled aluminium with a half inch piece of dowel on about 6 thicknesses of blanket.
The aerial is a working one connected to the receiver which is 27Mhtz 2 channel.
Apologise for the prop I originally made my own it is somewhere in the shed!

Huntress
Hi all this model was scratch built using the free plan Sparkler as the basis. She is just over 16 inches long and has a 380 geared down 1 : 2.
Unfortunately she was over-powered and on 6 cells only has 2 or 3 inches of the hull is in the water. I have slowed her down a bit but it is difficult to ballance the hull. Either the hull is climbing a hill or just splashing through the water. I built her in 1986 so she is getting on a bit. The pulpit is brass tubing and painted silver. The perspex wrap round screen was fractured a while ago and left for several years, then I decided to replace it and it is fine now.

Mary Ann No.2
This is another Mary Ann, I bought her off ebay after a good negotiation to lower the price. She was built as a decorative model quite attractive but again many problems. All the glueing was minimal and I just lifted off the cabin!
I stripped her completely and drilled into the deck to get an opening for the engine and RC. I grasped the side gallows to pull them off expecting brass they were delicate laser cut wood! So a recent model! I had a spare brass pair and that is what is on her now.
The prop and shaft are just a short push in dummy! So a new shaft hole was opened up, I did an initial fit of motor and prop and into the bath, luckily I did not walk away! I watched the water coming in. This took a while to sort out and I had to open up the forward bulkhead which was sealed in. I poured in varnish and swilled it around and then poured the residue out. After drying I found the main leak and as I was not going to re-do the planking and I remembered seeing a fishing boat drawn up on the beach and it had additional planks nailed on, I presume repair leaks. So I did the same.
She is a different colour as these fishing boats should be white hulled, this is because both of the Mary Anns work from a single 4 ch. Tx. (reference Admiralty Naval Intelligence November 1942)
This I have found may need a more alert brain than mine to do successfully! The right stick, no problem but the left (hand and) stick do not give the right rudder movements when coming towards me. My left hand needs re-educating.
I found the father and 2 sons crew lurking in my garage and after I got them new gear here they are.

Lilla Dan
Lilla Dan but not as you might know her! She is an extended version 36 inches stern to bowsprit. The hull is a Graupner Elke fishing boat hull. The plans were kindly sent by Billing 20 odd years ago.
However I am the new owner as she was built by my late friend John Cook. I bought her earlier in 2022 and did an update on the insides and renewed all the rigging, which took quite a while and rather than serve the lower parts of the shrouds I used white heatshrink electrical insulation.
She needs a good breeze to sail and really hates tacking through the wind and wearing ship can lose all you gained previously. However my daughter in law got her to go very nicely.

The Schooner Theresa
Here is another of my yachts, the hull is 40 inches loa and the bowsprit makes her a bit longer. She was built by my late friend John Cook back in 1965 and first came to my notice when many years later we had a club stand at Olympia.
I had offered to take the boat and John said he would be along later, so he was very surprised when he arrived and found I had assembled the boat. (To some eyes it would be a jumble of sails and spars). We became friends then.
I bought the yacht from his estate when he died and started refurbishing her. I simplified the RC and kept the double drum winch as it works very well. Replaced the 2 hatches in keeping with the rest of the boat, they have custom made brass pins on a retaining string to keep them located.
All the rope rigging had lost it's strength and was replaced and there was a lot of whipping to to do on the spars, this is something I like doing.
The paintwork you see is original I just cleaned the paint and gave it a spray of varnish, the sails are cotton and also original. The winch system looks the part where it can be seen on the deck, it is functional and easy to adjust. The plans and building instructions were in one of the old F.J.Camm A5 size books on model yachting and about 6" X 4" but the table of 'off-sets' was the main guide, John drew them up to full size and the construction is plank on frame and has well stood the test of time.
She sails very gracefully and responds to the helm easily and always draws a small group of people when sailing.
I keep her in a large 'Christmas Tree box' a plastic one with a lid which is excellent for model boats. Most of the plastic box makers do them but they only come out at Christmas!

Condor
This was drawn up from a 6 x 4 plan out of Yachting Monthly and is called Goosander. She was designed as a home buid yacht 27 feet loa 4 berth. My model is 1 : 12 scale. The hull shape is unusual being a double chine. When I came to draw up the plans it was not easy to accomodate a little more displacement and still balance the hull. This involves keeping the waterline right and doing some calculations for in and out wedges for heeling over and staying level.
She got wet for the first time in 1975 and then having learnt a bit more about sailing I gave her a re-fit in 1990 and entered her in the Class C5 in the Model Engineering exhibition where she gained a Bronze medal. She sails remarkably well and also has a small prop, (purely for lunch time purposes of course).
I found some more detail photos. The stanchions were mechanically drawn down to size on diameter from some Aluminium rod to match the brass tubing used at the pulpit and pushpit. The anchor sits at the bow and takes any knocks etc. The side view shows the tabernacle used to hinge the mast down. She is fitted with life saving apparatus. The handrails are cut from the solid and were a bit fiddly to make.
I recently did a few repairs and some changes to the jib arrangements and the photo was taken a week or so back.

Mary Ann
Hi all I like fishing boats and this must be one of the most popular judging from prices. This is an old one with brass fittings. It took me a while to recruit the crew as the hours are long and no holidays. She runs with a Monoperm on 6 cells and a small brass prop. The esc is a very small pcb one from China. I have another one but different colours can't go to sea yet as no Captain!

Fishing boat Norderney
I bought this boat at an auction it was started but not much more. I paid ยฃ40 and when I got home I found a ready made set of sails wrapped up in the plans which are from Graupner.
She sails with internal ballast and a small (drop down) keel, but this is fixed. Against Graupner advice with internal ballast she sails very well. Not great into wind but easy enough to control.
I used a Hitec arm winch but this was too fast so I used a slow down circuit which works well. There is a motor so needs a 3rd. channel.

Ferry from St. Lawrence Seaway
This is my version of Glynn Guest's free plan of Ogdensberg. I have timed it as the 2nd. August in 1937, which was the August Bank Holiday and the cars are all left hand drive with passengers for each. There is a story behind each group for my own satisfaction.
The main s/s is located on brass ferules that come with servos, the lifebelts are the 'heads' of brass rods that hold the s/s in place. Took me ages to work that one out. Motor is a 555 with an old Hitec esc and runs on 6 cells, moves nicely.
The ramps were made of coffee stirrers but it is crap wood and would not do it again, they do hinge down on dolls house hinges.
Of the vehicles all to 1 : 43 scale the most sought after is the motor cycle and side car, I put in her a very disappointed girl friend expecting a naughty weekend but ending up in a sidecar!

This was a gift but needed a complete re-build. The insides had grown with new additions and I took everything out reduced all to run from 6 D cells right down low. She had some rather unfortunate red sails but I have now fitted a new but original set of sails. Lovely to sail but rather heavy to move around for me now.

Clockwork boat
This was a collect it or it goes in the skip email to me. I went to collect wondering what electric motor it might contain. So opening up was indeed a surprise! "will you restore it"? the lady said. "more like a ressurection " I replied, however a collector friend convinced me to restore her. It was very crude s/s and heavy but very solid construction I reckon the mid 1930s the clockwork motor at first a mystery was revealed in an article by John Parker in his Flotsam and Jetsom series.
Turned out to be a top of the range clockwork motor and she runs for about 7 minutes. I put in RC! This was for the rudder and also a stop on the motor. I found by the time I got low enough to launch her the motor had run down!

Graupner Gracia
Gracia is my all time favourite! I had the plans and was about to build when I had an email from friend Keith Bragg who said would I like to take on his inherited part made kit, I jumped at the chance. It took me a month including planking the deck and making the sails, and she looks great on the water.
I have recently found some original sails and am contemplating revising the rig. I usually separate the mast and sails and store them in boxes, so this would be another mast with new sails so I would be able to choose from 2 rigs etc.
RC is simple winch with a far pulley on a stick so that it can all be withdrawn for maintenance. I finished her summer 2006.
I have found some more pictures of the winch - on - stick which locates into a slot at the bow and the joggling of the planking. This is the stern and you can see the tiller arm.
This is made of 11 laminates of 1/32 inch ply and shaped to fit over a 13 amp brass mains socket single pin. This is handy as it has a grub screw that retains it on the rudder stock.
It is the second one as the first one was nicked while the boat was on display at a show!

Nordfjord
This is a version of Glynn Guests Norwegian ferry free plan. I built my one from obechi and not balsa and she was top heavy, After much thought I sawed my one through just at the foredeck level and added 8 inches with appropriate lead ballast. I turned her into a cargo carrier which is exactly what was done to many of the ferries after WW2 due to the high cost of steel.
The various derricks are made from an old 27Mhtz aerial so very light in weight. They do articulate.
My model runs on a 555 motor on 6 volts with a 45mm brass prop, but there is enough power lower down to control the speed on the Tx, trim control alone. She has had a lot of admirers and running at slow speed my initial problem duck turned into a swan.

Although no longer in my possession this a kit from the late 1940s. I was asked to finish an already constructed hull and there were the plans to go by. The drive is an orange and black Hectoperm motor, which I supplied so in keeping with the era well just about.
She drives like a dream and even though I was paid well I found it difficult to part with. She is about 42 inces loa, originally for i/c.

This is a conversion of the Amati static kit to RC. She is about a metre long and looks very graceful when sailing. Note for display purposes there is a 1 : 35 scale crew on board as well.
The kit is on sale and you can also buy a booklet showing the conversion which I wrote with the kit, all rights sold to distributors.

This a bare hull I bought a few years ago, I think it was made in the early1950s judging from build. She had a sealed deck and I used my worm camera to look inside down the mast hole. B & B construction so I delved inside and fitted RC and kept it looking like a Pond yacht. Interesting part is there are 2 hulls almost identical and I am working out a new rig for her.

This an Aeronaut Bella with a gaff rig. 3 channel RC as there is an additional tweek to tighten the fore jib, makes a big boatspeed difference.
I like the old 40 Mhtz sets with a flick arm for the 3rd. channel and I use this to flatten the jib after a tack.
I had to fit a bowsprit because of the extra sail, and also move the mast back about half an inch.

HI Ronald, loved your video and Gary always makes me smile, so for me a great start to the morning.
Personal comment on the yachts, they are best sailed as upright as possible, Gary's sail boats looked just right.
Several of the other yachts could have done with a smaller suite of sails and one or two skippers some reminders of how to go around the buoys!
I think no ill will was intended but many model boaters know where their models are, but necessarily, where they are going.
I am going to watch again!
Well done

Hi all, I have been reading about placing decals on models. I was shown a different way which might surprise.
So, perhaps not for transfers but decals thin plastic and sticky this works very well and I have used this way for many years.
First peel the backing off and place the decal into warm soapy water. Leave it for a bit and make sure the surface it is to be stuck on is cleaned and wet.
Take the decal out and position it where you want. It can be slid about until you are happy. Then, with a sponge, start at the centre and firmly squeeze out all the water and any bubbles. Because it is warm, the decal will take up any slight curve without any difficulty.
Gently wipe dry and job done!
Yes I didn't believe it until I tried it!
I was finishing a model yacht (Graupner Libera Ocean) and it has the name about 10 inches long to be applied to the hull sides.
This way it was placed exactly in the right position, which I doubt could have been done the dry way.

Hi all, nice to do the maths but which is most important, the calculation and solution or constructing a practical model?
When scaling down from a prototype as we know, hulls and sails do not change in proportion to each other. I start from the size of the finished model, i.e. will it fit in my car and also have a place in the house.
So working out a suitable hull size comes first. Dividing the model length into the prototype length gives a scale. The cube of the scale gives a 'scale displacement', in some scales just not practical! All my models have to earn their living at the lakeside.
It is fortunate that to make a model sail, the invisible part under the water can be doctored in many ways.
The models by Glynn Guest have relatively crude hulls and what used to be called 'stand off scale' appearance. I have built several and they look good on the water. I also enjoyed the construction.
So we have to decide where your interest lies? Doing exact calculations for hull displacement is conditioned by sailing in water (and waves) that have obstinately remained at full size.
Hull displacement calculations could have a 10% error but it would not be noticeable when on the water. Bearing in mind that all the mentioned calculations have an end in practical sailing.
If only constructing a display model the numbers are irrelevant!
It reminds me of the radio control of the 1950s where the boat was the least important aspect of the model!
Just my two pennorth!

If you look at the hull lines, draw the limiting line under the hull before it drops at right angles to the keel. Everything above is the hull to use in calculations.
The keel is then measured almost as a trapezium in cross-section by the area.
With a hull built and ready to float and weighted correctly fore and aft. I put the hull into a bath full of water. I do not make big ones any more!
I have already put some cheap masking tape around the middle and side of the hull. With a pencil I push the hull sideways through the water.
Find the sweet spot where the hull moves evenly, not going to one side or the other, and mark it.
This is the CLR.
When the sail area calculations are done and the C of E of the sail area is worked out, it is this point that should be placed 4% ahead of the waterline length. This will give a nicely balanced sailing attitude.
The mast can then be mounted in the position already determined by where the C of E is to be. I do all this before working out where access and s/s should be.
By this I mean with sails at 30 degrees she will sail a straight course with no rudder adjustment needed.
My last 3 yachts have been set up in this way and they work fine.
With Bella there was a set mast position on the plans, I ignored this and moved the mast position back aft 2cms, which was as far as I could.
To get a better balance, i installed a bowsprit and the fore jib is moved forward until the C of E is just ahead of the CLR by 4%. The length of the bowsprit was now determined. Fittings were soldered up and she looks just right as well!
The fore jib is on a loop and fixed, but after a year sailing her I decided to have a standard servo with a small arm fitted to pull in the fore jib sheet and tighten sail.
The effect is dramatic! Careful control creates a wind slot for the jib and main sail and she speeds up.

I don't think the extended keel is taken in to account in the calculation. The numbers I see are 0,45 - 0.55 for sailing yachts.
When I modified the Aero-naut Bella yacht I beefed up the keel with 3mm bass wood each side as I did not think a 3mm keel could support a 1 Kgrm lead weight.
It was given an aerofoil finish and the 2 keel weights were screwed back in place.
I worked out the additional buoyancy from the keel which by chance equalled the filled in lead between the keel pieces. The waterline stayed exactly the same and the righting moment had improved.
With the gaff rigged sail suite I drew up and made, there was a 40% increase in sail area but the C of E had dropped much lower so she sails very nicely.
I am still trying to find someone with a standard Bella with the Bermuda sails to compare.

Remembering back too many years I recall multiplying frame areas 1-4-2-4-2-4-1 and doing things to them I have forgotten.
On another point of kit production by Deans. Ron told me that they obtained permission to produce models from original plans by Camper and Nicholson.
We had a couple of motor yachts, Melita and Dufresne and the very large yacht Blue Leopard. The proviso was that he could use only the prototype drawings and not adjust them for a model.
I talked to Ron when Blue Leopard was first put on the market. He challenged me to find out what he had done. As I knew what to look for I saw he had made the keel very wide to gain more displacement.
I was hoping to have the model to do a build review for the International Boat modeller magazine. The then editor was also a yachtsman and did not like the way it was set up as a model and said he did not want it reviewed.
I was a bit 'iffy' about it as well so there we are.
If anyone is interested the original Blue Leopard model yacht, which when viewed, does look good on the water is now on sale.
I have sailed this one as Ron let me take her out for a spin at the late Pangbourne model boat show now defunct and she does sail well.

Hi again another thing I frequently do is to work out the expected underwater volume of the prototype and then work out what size model I want.
Then scale it down. This usually produces a hull which is either too light or unstable. Using experience to judge what a practical model should weigh, I see about making the hull larger.
Some years ago I was asked to take a scale display model of a sailing yacht, and make it a practical sailing boat with RC.
The model is a metre long but weighed in at just 7 pounds. I calculated a minimum displacement of the hull for sailing and decided on around 11 pounds.
Lots of thinking came up with having no noticeable changes in hull shape. I did this by double planking with the first planking at 3mm and then the kit supplied 1mm planking diagonally on top. Unexpectedly the fine point of the bow increased the length by 2 cm, well you can't think of everything!
This was not enough. I gained the rest by making the keel fatter and extending it down by about 6 inches and then fitted a bulb keel.
The model is still available as a kit and is the Amati Endeavour Americas cup yacht at 1:35 scale.
The yacht has an enormous sail area and would overwhelm the model. So this was cut back which also allowed a backstay to be fitted.
You may have to pay extra for the conversion information.

Have you tried the old methods? I get a good estimate using the Prismatic coefficient.
This takes the immersed centre area bulkhead area multiply by the length at the waterline and apply the coefficient for that type of hull which will be a decimal value.
Yachts are around 0.45 - 0.55 ranging to bulk carriers at 0.95. A solid block would be 1.0.
Another way for similar ended hulls is to treat the ends as half each so two ends = 1 and then calculate the centre portion.
The first programme I ever wrote was to produce a look-up fanfold printout to do just this. That would be in 1966 and written in PLAN.
I hate programming! It can take you over thinking about it. I leave it all to my son.

There was a very good episode on a paddle steamer in Egypt!
But he is not the type to be too close to because of all the crime around him, dodgy altogether.
Captain Hastings is a product of the private schools in the early 1900s, terribly nice been in the army and trades on his last rank of Captain, but a good gopher.
However the actual filming is a delight and alternate episodes were directed by their own team and both won awards.
I love the old London taxis used and had a dinky toy model of one when younger.
The series could not go on forever and eventually he dies on his last case!
Other actors have tried their hand in the role but pale (especially the current one) into insignificance in comparison to David Suchet. Some might note his brother was a TV newsreader.
I should add I did like Peter Ustinov in the part!

I the Model Boats magazine a few decades ago there was a model boat kit review by a friend of mine and one of the photos was on the cover.
The graphics designer decided that the picture looked better if laterally inverted (going the other way). However his nautical experience was zero as the starboard side now had a red light.
Also when colour was first introduced there were just 4 pages of colour in the middle. A photo of a model boat was spread across 2 pages with the front half in colour and the back half black and white!

I have had a couple of set backs on answers lately, got this one right but lurking in the high 80's now.
It all makes a good talking point and generates much comment.
Off to the lake after I have had a coffee. Looks like a nice day but not much wind.

Nice set of pictures. I have always liked the Spray. But there are many versions of it among the plans available.
I am thinking of doing a deck layout on a 32 inch yacht hull I have which will be similar in layout to this boat.
My only enemy is anno domini as it edges on day by day. Today though it is off sailing on the pond.

๐ Names of Fishing Boats

Fishing is a hard life as we all know, we have a fishing series on TV at the moment (from 2018). It was to illustrate the changes due to the UK leaving the EU.
However it is an education about the fishing industry that many who just buy their battered cod in the suoermarket are just not aware.
The current technology is frightening with underwater CCTV of what is in the net and then using special 'pumps' that feed the fish into the hold without anyone touching a net.
The programme I saw had the skipper selling his catch for well over ยฃ1million!
He was fishing between north Scotland and Scandanavia and homed in on a shoal of fish 7 miles long! It all went to Sushi-land!
It is all a political football as the folk of Cornwall have found out. Rather than selling a fishing boat for conversion to leisure use the E.U. (when we were in it) said the boats must be sawn in half!

๐ Flywheels - gyros for stabilization

Hi Lew, I seem to remember prior perhaps to RC that the 'straight runner' boats could use a spinning gyro. It assisted directional travel and was more steady.
You said in your post "not spinning" not sure what you mean?
As far as bobbing about, weight distribution can help. Think of a barbell in weight training. If you ballast a model towards the bow and stern there is less bobbing about. But there is a penalty in steering.
I have a yacht that relies on internal ballast and not a deep keel and this does not bob about.
Cruise ships have stabilisers and there is an electronic device that senses movement that could be used to operate stabiliser fins. I think model helicopters and submarines use it.
A cheap way I read about was to have a tank of water like a slightly lengthened coke can and fill to one third with water. It would have baffles inside to slow the transfer of water from one side to the other and mounted high up.
This causes a delay in the water transfer and does combat the boat movement.
Intriguing!

We know now that there is not an infinite number of fish or any other living thing.
When men go fishing on a commercial basis they overtake the replacement rate of the fish.
In the North Sea we had the 'silver darlings' or herring, and they were fished out.
Actually when man goes to war, this benefits the fish!
During the 2nd. world war the fishing in the North Sea was very limited and over the 6 years the fishing stock recovered very well.
I have to say that fish is one of my favourite foods but I am still aware of the implications to the fish.
On a lighter note, my son and I have eaten fish and chips as a treat in many places.
In Australia NSW the favoured white fish is flathead, a really ugly fish but very tasty.
In Tasmania we had 'gummy shark' as the prefered white fish, also good, a bit like rock salmon (also from the small shark species).
My favourite though is skate, part of the Ray family.
As far as fishing boat models go I do like the North Sea Norwegian fishing boats of the 30's that have survived through to be tourist attractions now. They evolved as the result of years of fishing and bad weather.
The Billing kit Mary Ann is my favourite I have two of them plus an unfinished kit. The kit was almost the first from that company (1958) and it is still in production today in much modified form, well it has evolved as well.
When working on my latest model whenever I look up I see a Mary Ann and I smile.
I have included pictures from a week or so back. It would be nice to think that one boat had had a good catch. Unfortunately she was sinking quietly, another plank opened up maybe?

Sorry did not read the title!!! MM337 a very old plan!
This is only a guess but models of this era were built over strongly as they had to stand up to being gripped tightly between the knees to start the i/c engine.
You might want to review the strength of and weight and size of materials used.
I have just passed on a model not built by me but similar which is very heavy due to the above.
It will not plane with a powerful electric motor as it is too heavy to get the hull up, and part out of the water.
