    Hello Again,
    A little while since I let you catch up with progress on the Dutch Auxiliary Yacht, and I have been involved in adding the mahogany planking to the sides and a solid mahogany transom. The latter task was a bit tricky but was able to use clamps and rubber bands to help the glue bond.
    The planking was 5mm x 0.8 mm over the existing .8mm ply side. This went quite well and was only the second bit of planking I had done, so was reasonably pleased with the result.
    At this point I must say how much encouragement and how many constructive ideas I have received from Nerys. Her encouragement has been in the form of making my Dutch yacht have a Dutch look to it and has advised that I make leeboards for the boat which I have done, (not operational) and through experience she has advised that I deepen the rudder so that is more effective, so a second deeper rudder has been made.
    All this has made me search for images of Dutch boats on the Net and I am amazed at how many different designs and variations there are to look at and follow. Leeboard shapes and design are legion, so I have opted for what seems to be a suitable design for my boat. I am hopeful that with this wide variety available I will be able to evade criticism of things, โ€˜not being rightโ€™. The leeboards will have brightly painted head and foot, which seems to be the thing.
    Work has gone on well beyond what I am showing here and so my next blog will follow relatively soon, I hope. The final picture shows paper mock-up of the sails with other bits just taped in place and it is beginning to look like the picture on the packet! (Had there been one).
    Some of the delay has been as a result of the Woodbridge Model Boat Club reconvening and so have been sailing instead of building, which has been good.
    Thanks for your continued interest.

    Geoff

    Hi Geoff,
    That's a fair bit to be going inside, but I think you will need something on the keel to counteract it's natural wish to float. That's a good price for a sail servo, would you like to tell me where, please.

    Cheers, Nerys

    Thank you Nerys for your compliments. Yes I will be adding ballast to the keel, but am not certain as to how much. The plan shows a waterline so think I will ballast it temporarily inside and then transfer the weight to the foot of the fin. There will be a certain amount of weight within the hull, mainly the battery, a 6v Nimh which will be placed at the very bottom of the hull. There is a full size sail winch as well, a bit of an overkill for a boat of this size, but cheap at 9.99 and runs just the right amount of sheeting out.
    Best wishes, Geoff.

    Hi Geoff,
    What a delightful little boat you have built, I think she is absolutely lovely. Your mock up photo is great and shows her in all the glory she will have when finished. I love the mahogany planking, it will look wonderful when varnished. Seeing the picture of her hull, I think she is a lovely shape, but I hope you are going to put some ballast on her keel Nice to know that you have found pictures of all the myriad of Dutch craft and the wonderful decoration on them. Some of them have the most beautiful carving on them in places like the head of the rudder and all round the cabin doors.
    You are making good progress and I really look forward to seeing the end result and pictures of her sailing.

    All the best,
    Nerys

    Slowly making progress
    It seems as I have not posted an update for nearly three weeks, so my apologies for being a bit lax. Nevertheless, I have not been slacking, it just seems that the tasks I have completed since last blog have been time consuming, and have not produced much of photographic interest.

    The deck has been planked with 5mm wide planks and these have been sourced from slats from a discarded wooden blind, the finished stripped from its surfaces by belt sander, then fine sanded and cut into 5mm strips on the Proxxon circular saw.

    The planks were butted edge to edge and stuck to the frames with Evo Stik waterproof glue, planking over the apertures for the forward hatch and mast box, leaving me to rediscover them later. Planking was taken as far as the rear of the cabin and then the rear section completed, by using the slats at full width, but scored at 5mm intervals to simulate planks.

    As this wood is quite white I have just varnished it with Sikkens outdoor varnish, which is clear and water based and brushes are cleaned in water. Donโ€™t like spirit cleaners these days.

    A mahogany cover has been made for the forward hatch and has to be detachable for access to the Rx.

    Following this work the floor boards were made for rear well and were built in three sections, two at the fore, either side of the engine, and one into the rest of the well to the transom. The boards, as used for the deck, were laid on .8mm ply to make life easy and to keep the shape.
    The seating and back rests were glued to the formers and again using the wood from the slats but this time, stained as antique pine to match the boarding at the rear of the cabin. This will be varnished as above.

    Finally the โ€˜engine coverโ€™ has been built and finished with the stain to match. The top of the propshaft, with a rotating collet, is not fully covered and may present some health and safety issues, but people will just have to be careful!!

    That just about brings me up to date now but would like to leave this gem with you.

    From, โ€˜Build Yourself a Model Boatโ€™, published in 1950. ---'In these days of motor cars and wireless sets, most men can solder.โ€™ We still have the motor car and wireless sets, but can most men still solder?

    Geoff, used car sales person!!!!!! never, I'm just a simple sailor, with a love of traditional boats, and you are making what you are calling your Dutch Auxiliary, so you might as well make her look as Dutch as possible. Seriously, I do think a pair of leeboards will improve her looks and might I suggest you use a wood which will look good varnished. I expect the wood you have picked out will be ideal.

    JB, your so right, I told my son that I won't always be around to fix it for him, ans as he keeps buying cars that fall apart I've taught him to weld with gas, stick, mig and tig.
    So now I can call on him if I get stuck as I've given him my old stick and might welders.
    He still struggles with brazing and silver solder, but I am teaching the grandson to solder now as he has a steadier hand than me.
    Cheers Colin.

    Hi Geoff,
    I think you are making an excellent job of your Dutchman. Really good woodworking and you are obviously putting a lot of thought into the construction. You asked me about leeboards a little while ago. I think if you want to give the impression of Dutchness then I think they are essential.I have never made them on any of my barges or Dutch schouw to lower. Just have them in the fixed position. They will only cause drag if you lower them and not enhance the sailing capability at all. Your keel is going to do that. Anyway, keep up the good work.

    Cheers, Nerys

    Nice work so far Geoff, good bit of re-cycling as well. Re soldering- like many people, I can MIG, gas and arc weld,- and solder, but my son (28) doesn't seem all that keen to learn (more into computers). Young people are probably going to end up pretty useless (practically) in the future. Most young people learn from the net, but that's not always accurate and can get people into trouble. I've seen some pretty dangerous advice given over the years.

    Looking good.
    I know what it is like with planking as i have recently done quite a bit of it.
    But the reward is when you see it varnished.

    The more I proceed with this project of scratch building the more I realise that I have to make my own way through the build without a nicely illustrated Handbook.

    But it does give the chance to switch from one part of the build to another. The cabin has now been built, top planked and varnished and two doors made. I think I may only have room for one door in the cockpit due to having to enclose the 'engine'.

    As far as the hull is concerned I have added the two top side sections, sanded and shaped all smooth. The bow blocks have been added, and similarly carved to shape. The whole hull has been given a coat of eze kote.
    In the meanwhile I have been making one or two of the fittings for future use.
    As I go through this hull building, I wish I could have had some sort of jig on which to build the skeleton of the hull, but it has curvature on the deck and so a flat jig would have taken some time to construct. But some distortions have crept in due to having to build the hull 'in mid air'. I will do my best to disguise these as I go along.

    The cockpit panelling at the front has been added also. I have included a mock up pic to give a little idea of what the craft will look like.

    The build goes on.

    She's coming on very well Geoff. She's different enough to be a bit more than interesting. I like. Looking at your rudder, might I suggest you fit a drop down extendsion to it. I think it would improve handling. I have done that to all my barges and my schouw. Another thing, as you are building her as a Dutchman, why not fit leeboards to enhance that conception. Whatever, you are doing a grand job.

    A Step Further.
    Having decided to build the cabin as a detachable unit rather than build to the hull, it gave me a chance for a bit of light relief from the hull building.

    So setting about the cabin I drew the outline of the base and built the cabin much as I had done with many model aircraft, over the plan, This worked well and the unit comprised four sides and three roof cross bars. The pic shows this built to this stage. Portholes had been cut into front and two sides. These will be copper washers stuck onto a an acetate โ€˜windowโ€™ and then this stuck over the drilled holes in the sides. To complete the cabin it will be roofed with .8mm ply and then this planked with mahogany veneer.
    Back to the hull, the bottom planking has now been sanded smooth and the .8mm ply sides added, as far forward as former 1. The triangular void at the bow will be filled with balsa block.
    Sub frames for the deck bow section have been filled with 3mm ply to receive screws for bowsprit fixings and ply apertures to support the deck planks around the forward hatch and the mast box. (Please excuse wide angle lens distortion on last pic.) More soon

    Thanks for this Ron, I have not yet decided how the cabin with mate with the deck, but the decking will pass around the sides of the cabin. I have decided to do this as, from the plan the cabin looks a bit tall for this type of craft, and so it will reduce the apparent height of this part of the boat. I intend to make two cabin doors that will be stuck to the rear of the cabin and will extend into the footwell. However must not give to much of the story away just yet! Best regards

    Moving On
    With all the bulkheads firmly attached to the keel the upper and lower stringers were attached.

    This is a flat bottomed hull and I have decided to plank this directly onto the frames. I have acquired some old slats from a wooden blind which have given me the material to create planks for the bottom of the hull. They have a finish on them which has been removed by belt sander on the side to be glued, and they have been affixed to the frames to form a very solid hull bottom. I have a feeling that this model is going to be something of an apprentices exam piece as I am using a few different techniques in the hull construction. The sides will be .8mm ply with mahogany veneer thickness planking and the bow section is balsa blocks. The deck will be planked with the same material as the hull bottom.

    With bottom successfully planked the next building step would be to add the ply sides, but before I do this want to make sure that the gear will fit into the hull satisfactorily.
    For the motor I have chosen a small 280 motor with a short shaft which is sold as replacement for the power units in the Crocodile Heads. From Banggood these were minimal cost and a suitable prop was bought from the same source, as was the 10 amp ESC.

    I wanted to mount the motor as neatly in the boat as possible and have opted for it to be in the well area and be covered with a mahogany casing. I have opted for a rubber band drive which works well in my Mantua Mincio, and allows the motor to be mounted below the shaft. Using an 8mm pulley on the motor and 12mm on the shaft, giving a 1.5 reduction.

    I considered various winching arrangements such as a standard servo with an extended arm which would give only a short travel for the main boom. A standard arm winch would not have sufficient room within the hull to move. Finally I have purchased a two turn standard servo size winch from Howes models for ยฃ9.99 which will give me adequate control over the main boom. It will be mounted at deck level with the winch drum inside the cabin. This allows the battery, a 1600 5 cell Mnih to sit under the winch in the bottom of the hull. This can stay in place and be charged as required.
    The Rx will be mounted on the first bulkhead by Velcro and will be accessed by a hatch in the deck, The ESC will be between bulkheads 2 and 3.

    A mini servo will be fixed to the transom for the rudder control. See all pics.
    I have loosely rigged this all up and it works quite satisfactorily.

    Totally agree with you Geoff, ๐Ÿ‘
    Some years ago I was Deckhand/Mechanic/Chief cook and bottle washer on a ca 12m yacht sailing out of Portoferraio on Elba.
    https://www.google.com/maps/place/57037+Portoferraio,+Provin...
    No way was I gonna get her out of the harbour with only the lightest of breeze (out of the wrong direction anyway) without some kind of expensive disaster!๐Ÿ˜ฎ๐Ÿ™ˆ๐Ÿ’ฅ
    Original intention was to sail to Corsica, but even the light breeze vanished as we came out of the harbour and round the headline.
    https://www.google.com/maps/place/57037+Portoferraio,+Provin...
    So we just pottered round to Golfo di Viticcio on the motor, anchored off Caletta Pinetina
    https://www.google.com/maps/place/Caletta+Pinetina/@42.81731...
    and spent a very pleasant day picnicking and snorkelling in the bay. Wonderful crystal clear water ๐Ÿ˜Š
    Burnt me fingas on the way back repairing a leaky cooling pipe coz the motor was overheating! ๐Ÿค•
    Still have very happy memories of Elba though๐Ÿ˜

    Thanks Ron for your response. The motor will be controlled from channel 2 on the receiver. (Mode2)
    This is the right hand stick with channel 1 controlling the rudder. with the stick at neutral position, right and left will control the rudder and up stick will control motor forward, proportionally, and down stick reverse, proportionally. I am used to flying model aircraft so am familiar with controlling two functions from the one stick. The left stick will control the sail winch, from full out to full in.
    I have sailed full size dinghys, and model racing yachts so am familiar with rudder tricks.
    I hope I have not offended your idea of realism, but am not concerned with what happens in real life, I am finding this an interesting model to build and looking forward to sailing this when the times comes as a little boat of fascination.
    Best wishes Geoff.

    I know that some sailors use their auxiliary power to move in and out of the harbour and in other situations. I considered a similar build, though with sails being furled, which would then not require a Servo for sailing.

    Sometimes on ponds the boat has sat out on the water becalmed. In those situations, I have used the rudder to move the boat along.

    How will you turn the auxiliary power on/off?

    Thanks for the thought Martin, and an O ring would probably be more durable, but might induce more stress on the motor and shaft bearings. I have never had a band shed on my Mincio although they tend to be not very durable, but I bought a 400 pack last year when I finished the Mincio and so still have a few left! Best wishes

    Thanks for your interest Ron. The original model was planned to have a diesel, clockwork or electric motor and is indeed titled, Dutch Auxiliary, so I am building as suggested. Also it engages my planning and thinking in producing a model yacht with auxiliary power. As another consideration, my local pond at Woodbridge is surrounded by trees on all sides at varying distances and this gives very fickle winds so an additional escape will be useful.
    Hopes this explains,
    Best wishes Geoff.

    If you are going to be sailing this, why go through the process of installing a speed control and motorized? This looks to be about the size of the footy ?

    Hi Geoff,
    You say that the rubber band works well on your Mantua Mincio, but i would think it would bunch up and release in operation.
    Have you thought about using a large thin 'O' Ring ?

    Keep up the good work.

    The next steps

    The bulkheads were notched for the stringers and keel and all dry fitted to ensure a good fit, but before they could be fixed to the keel it would be best to fit the propshaft through the keel. The bottom stringers had been fixed to the keel and it was considered that to just drill a hole for the 5mm o/s propshaft would be all that was required. But, alas, this all went wrong and the keel was ruined and it was never going to hold together again, with just the small section of the keel behind shaft somewhat adrift.

    So I had to take a different tack, I cut a new keel and was able to salvage the fin from the first and fit it satisfactorily to the new keel. On consideration as to what to do next I fitted one side of the lower stringer to the keel with a doubler on the same side. Turned the keel over and sawed the slot for the shaft in the keel. This left the keel intact on the stringer and doubler, and then the stringer and doubler on the other side were added. This worked well and I could proceed.

    The bulkheads were fitted and epoxied to the keel, two or three at a time to get them lined up. To get the angle of the transom to the keel, a piece of balsa was superglued to the end angle of the keel and the transom clamped to this.

    I have included a pic of gloves that I use to aid grip when using a knife or fretsaw or Proxxon circular saw. They offer a bit of protection against slippages and also allow a firmer grip on the workpiece when sawing, especially the fretsaw. They are quite comfortable to wear and are available for around ยฃ1 at discount outlets and builders merchants.

    I must say that this model is occupying a lot of my thought as to how it will all fit together with the radio gear and the rigging and running rigging. I want to preserve the open well at the back with its seats but the top of the propsahft will protrude into this space with the motor as well. The cabin I will probably make as detachable to give as much access to the 'hold' as possible for fitting and servicing the equipment, but more of that later.

    Thanks for comment Martin, yes it is a steep angle on p/s, it is a short shaft and I wanted to get the inboard end above w/line. If I had used a longer shaft it would have taken the motor into the area reserved for the sail winch and battery. I considered the angle, but after all in a model of this type, forward thrust need not be at full potential. Regards Geoff.

    I don't know if it is the camera angle or just me but the angle of the prop shaft looks a little steep.

    Getting Under Way
    With these thoughts, I set about the build. First the keel. This would not have a detachable portion, bolted on as per plan but a hardwood fin keel jointed into the main keel and glued, (epoxied) into position, similarly the stem was half jointed as the plan but glued in place without the screws! The keel was then notched at the bulkhead stations as shown on the plan.

    In the past I have bought bundles of hardwoods from Hobby Craft and this furnished me with some dark wood from which I have been able to construct the keel fin. The two pieces were joined vertically to give the required width and a third piece horizontally across the bottom to cover the exposed end grain in the verticals.

    As a means of getting a start I made the rudder and tiller. In the past I have bought bundles of hardwoods in packs from Hobby Craft and this furnished me with some thin dark wood. I cut two pieces to outline of the rudder and laminated them with a piece of .8mm ply as the core. This I consider will keep the component free from warps and an offcut from this was used for the tiller arm. As a decorative function I have reinforced the join with two brass pins.

    In pursuit of Dougโ€™s passion for people in boats I am figuring on having a little man sitting on the seat in the well with his hand on the tiller, his arm moving with it! There are so many possibilities with this model. Again, from within the site, Nerys has suggested that the boat be gaff rigged so this will happen, I expect. So much encouragement and ideas from members, thank you all.

    The bulkhead patterns were derived from scanning the half forms from the plan, printing two copies, cutting each half shape out and pasting them, mirror image, onto a piece of cereal packet. (I remember someone else saying on the site, never throw away a cereal packet, more good advice!)

    These were then cut out carefully and pinned to the ply and drawn around, Then cut out by my trusty Draper Scroll Saw.
    This is just the starting point, with the bulkheads in outline only so far, they have to be notched for the stringers and also to cross halve with the notches in the keel and the centre portions cut away. Fitting the RC gear and motor /propshaft is going to be challenging in a model of this size. This could almost be a prototype as little detailed information is given on the plan.
    I would hate to try to start a Mills .75 in this model. Thankfully we have modern batteries and motors now.

    DUTCH AUXILLIARY.

    This build blog been brought about by chance and is project which fulfils a leaning toward nostalgia in a few ways. My last build had come to an end and had proved successful on the water, and I thought that building had ceased, as we humans would be released into the wild again, perhaps building would take a back seat during the summer months.

    But on reviewing some of the folders in my workshop I came upon a couple of plans that I had bought two or three decades ago intending to build them one day. One was a MAP plan of Tornado, a small high speed launch and the second, which is to be the subject of this build blog, โ€˜Dutch Auxiliaryโ€™. I remember gazing at both these models in the MAP Plans handbook of the day in the 1950's.

    The nostalgia kicked in and I decided I must build it. Designed for Model Maker in the spring of 1952 the construction shows all of the ideas of previous eras. When I was about 11 or 12 my elder brother, some ten years senior, bought me a book for Christmas, around the time this plan would have been published, Model Boat Building, sixth edition 1948, by F J Camm.

    As an impressionable youngster I gathered that, whoever he was, F J Camm must be the fount of all wisdom as he edited all the โ€˜Praticalโ€™ magazines of the day , be it Wireless, Television, Motorist, Householder and so on.

    The design of Dutch Auxiliary follows many of the ideas shown in this book and the idea that the model should be sturdy is reflected in the use of 3/16 ply formers set at 2 inches apart in a 16 inch hull which seems a bit hefty. The junction of the stem to the keel using cross halving joint and screws seems to show how jointing then did not have the advantage of our modern adhesives. In fact I did wonder if the designer had recently retired from building Henry 8ths Fleet of warships and did I ought to go out and buy and adze!

    The final bit of nostalgia came from the fact that on my first holiday from work in 1979 I enjoyed a week on the Norfolk Broads with a teenage mate in Whippet 11, a small two berth yacht fitted with a British Seagull outboard and this design bears a similarity to that boat. (1930's Whippet - Broads Cruiser Renovation By Chris - Boat Renovation People (boat-renovation.com)

    The plan has not a great deal of detail, the bulkhead lines are shown in half section with a side view of the keel and plan view of the deck and lines, with step by step drawings of the assembly. It was to be skinned with 1/16 ply on the hull, deck and cabin top. A plain dowel for the mast and just an outline for the sailplan and simple rigging to hold up the mast, set in a brass ferrule attached to the keel. The auxiliary can be either a small diesel engine, electric or clockwork.

    In this relatively simple design I can see the chance to make a small model yacht which has a degree of class, if built using dark natural hardwoods, with a tapered wooden mast, hardwood booms and bowsprit. The hull can be skinned with a thinner grade of ply, say .8mm, and then planked with a similar thickness of mahogany. The cabin again would be dark hardwood as would be the seats in the well. The deck could be planked with a light wood.

    The power unit, with not a clockwork clock in the house and having sold my small diesels 50 years ago, would have to be an electric motor. The pics show a bit of an overview of the Plan and building will commence with next blog.

    Nerys, Thank you for your prompt reply, and the information there in.
    I have since found a sail plan from a schouw and this will give me some exact dimensions to work to, scaled to the size of my boat. Thanks for the information about the loose jib, it was concerning me that in a boat of this size, to have to control both sails from one servo would be tricky. In the past I have sailed Marbleheads and R36r in competition and have dismissed the idea that,, in this boat, a full 90 degree sail sweep is not going to be possible nor even desirable. So a small sail movement will be adequate and, of course, with the auxiliary engine I will be able to get out of trouble!

    The amount of thought that this model is provoking is mind-blowing!

    Best wishes Geoff.

    Hi Geoff,I think that picture would be a very good one to follow in your build. If you look in 'My Harbour' you will see that I scratchbuilt a Dutch schouw yacht some months ago with a similar rig. She sailed very well and I was more than pleased with her. Both main and staysail are loose footed. I cut the mainsail with the curved head to fit the curved gaff which I had previously carved. The mainsail was tight laced to the gaff, in fact, sewn on. The luff of the mainsail can be either loosely laced to the mast or, as I did, laced to mast rings, which I found amongst the jewellery findings in a craft shop. The foot of the mainsail is just fastened to each end of the boom, that gives a nice curved flow to the sail. The staysail is held to the forestay again with small metal rings, about 5mm diameter, from a craft shop. I use them on jibs and staysails on any sailing craft (mainly Thames Barges) I build. The jib is loose footed and is sheeted with a loop of string loosely going from one side of the boat to the other left loose enough for the foot of the jib to have enough flow to be following the curve of the bow. The clew of the sail has a small ring on it and runs free on the sheet. The jib, or staysail, is thus self activating and does not need a servo.

    I hope that answers your queries, but if there is anything else, or I'm not clear enough, please let me know. I'm only too pleased to help.

    Best of luck, I look forward to updates on your build.

    Nerys, Thank you for your idea and I have found this pic on the net which I think may be an example of what you are speaking of. It would certainly give me the idea of what is required and I wonder if you would kindly comment on these items for me.

    1 It looks as though both sails are loose footed.
    2. The main is laced quite loosely to the mast.
    3. The main looks a though it is quite closely attached to the curved jib, how would this have been fixed.
    4. I think I could well use this as a pattern to follow your idea.

    Many thanks Geoff.

    Hi Geoff,
    A blast from the past.

    As you say with modern materials and glues she will be lighter.
    And add your skills to the build and she will be a great sailing boat by the time she is finished.

    Good luck with the build.
    I will be following.

    What a nice little boat, certainly looks to have some Dutch influence with that high sheer towards the bow. If she was mine I'd give her a typical Dutch rig with a short curved gaff. Please build her and show us progress in a blog. she's the sort of boat that really appeals to me.

    Cheers, Nerys
