    I guess this nearly correct answer is where AI extrapolates from it's data a possible reason why the dinghy needs bouyancy. Those that have sailed dinghys will have experienced a capsize.

    I remember going through the capsize drill in the Solent in April and not a very warm one either.

    Hello Alessandro, I thought there maybe a new perhaps lighter and better SLA battery around.

    I have used Cyclon cells, lead acid, but very similar in actual discharge capacity to NiMh cells. They do not seem to be around much any more.

    These are AGM (Absorbed Glass Matte) but measured at the 5 hour rate as NiMh cells are. The SLA batteries are measured at the 20 hour rate.

    Hi Steve -s I too like to have a book to refer to as well. We may well be the dinosaurs here, on the other hand we can read our book without having to have a 'signal' or broadband etc.

    We can find somewhere quiet and with the technical books I have some paper tabs to act as page markers. Too many times it has taken ages to get back to a particular item or reference.

    I have belonged to one library or another for 80 years now. I could hardly wait to be 7 when I was first allowed to join a library.

    There is nothing personal here for you, I was surprised the new technology in batteries had gone into small batteries.

    I just wondered how many members of this forum were aware of the batteries now in their cars.
    I mentioned my experience, there was nothing in there for you, or about you, Alessandro.

    I Googled the battery you mentioned and read the technical details. I note the FG graded batteries are referred to as SLA in their own literature. Apparently similar to the good quality batteries we get Yuasa etc.

    Personally, I stopped using SLA batteries some years ago as the weight to power ratio was unfavourable compared with NiMh batteries. I do not like LiPo cells but that is just my opinion.

    Experience also tells me that long documents frequently get the initials TLDR.
    Best regards

    Thanks for the detail.
    Cars with stop/start function have to use a different battery to the standard type battery and cost twice as much.
    Quote:-

    One technicality though, a normal lead acid battery cannot run this system, so special batteries are needed: Absorbent Glass Mat (AGM) and Enhanced Flooded Batteries (EFB).

    The EFB batteries are for the larger cars altough also work for smaller cars.

    Other information I have come across requires a special charger with a lower cut off voltage for the charge voltage.

    I got into this as I had an old battery monitor from my last car which I plugged in to my current car and it said I need to re-new my battery.

    But apparently the battery voltage is limited to 13 volts for the advanced batteries but the old lead acid batteries are allowed to have 2.4 volts per cell i.e. 14.4 volts on full charge.

    Confusing? Yes but with 60% of the cars in Europe on S/S need these batteries.

    Do not forget the Billing Mary Ann kit. It is a Danish design to do the same job of catching the herrings as the Scottish and N.E. coast fishing boats.

    It was boats like these that were the Wartime Shetland Express from Scotland to Scandanavia.

    I have mentioned it before but there is an obscure fictional film called "Suicide Mission" which features the story.

    The engines in these boats were the old gas engines and were very noisy. They could be heard way before they were often seen!

    Hi Ronald, the fishing boat I am working on was a model built from the Underhill plans, currently on 3 sheets at ยฃ25+ each sheet!

    I guess it was built 50 years ago from these plans, and was passed on to the lady I bought it from. She had had it for a few years as a gift from a neighbour. It was on sale on Gumtree for ยฃ12! I paid for transport from Scotland to Herts. And was very pleased with it on arrival.

    After enquiry I found the 992 number had never been reached so it was a bit of fiction.

    I love it!

    Hi all, the Q o D is the most popular thread on this forum so rather a lot of us like it and it is a bit of a challenge. Questions about model boats are limited and often subjective.
    Most of us make models of prototypes and that is in the main what the questions are about. I have to admit questions about regulations are not relevant as they are the ins and outs of ship life.

    So apart from that I am game for most of the questions and as other members have said a bit of logic to exclude some answers and deduce from the questions parts that appear in the answer options give the answer anyway.
    Ed points out they are a bit of fun and sometimes things go wrong!

    I would vote for rather than against, I have my private war with A.I. as many will know but it is all a bit of fun.

    The only kits I know of are for a Fifie. I think there are 3 kits from different sources.
    The Fifie is pointed at both ends, there are a lot of plans on Sarik for them and the late Sandy Cousins wrote an excellent article on his build in Model Boats magazine maybe 20 years ago.

    The photos you show are from the north of Scotland from Wick, many similar ones are in and around the Western Isles.

    The Scottish Fishing museum is there as well and I had a very kind Curator give me details of the fishing boat I was working on.

    My model turned out to be a Harold Underhill plan of a Ring Net fishing boat with the registration CN992 this is a fictional number CN is Cambletown. The plans are very expensive!
    I am restoring this model 24 inches long as it was built as a decorative model and the waterproofing is taking time.

    The scale of 1:24 will give a working sailing model and simple radio will suit, I use monperm super motors but a medium 380 with a 35 mm 3 bladed prop works well.

    I prefer the 1920s/30s era models but some of the modern ones look OK.

    I was intrigued as I had not heard of Paxlovid before. It is available on NHS free in UK.
    The test data shows how very effective it is.
    How much does the medication (5 days) cost in US?
    I read data from 2022 which suggested $530 per 5 day treatment. Under health care insurance is that free?

    I use Ali express and have found them very good sometimes the wait is a bit long but that was in the blurb before I bought the item.

    A recent purchase was 4/5 size sub C 2800mAh NiMh cells which have proved to be excellent. I am no longer bothered by batteries from China.

    They perform much better than the AA cells of similar capacity.

    Hi Ronald digging up history can have some unexpected results.
    You are right the boats were built on the Clyde.
    So how were they paid for?
    The finance came from cotton produced in the main by the slaves in the southern states.
    This was traded in Lancashire which became renown the world over for its cotton goods.
    The money from this was used to pay for the ships built on the Clyde.

    Ironic for the slaves who picked the cotton and that their own labours were keeping the slave trade going.
    Is it best not to know? This is not meant as a political issue, just history!

    I bought a Harbour defence launch built before the MAP plan came out from the estate of a friend. I admired the boat when he ran it but he had problems I did not know about. When I tested it in the workshop I found the prop tube and the rear bearing in the water were not aligned and the resultant drag had each motor taking 5 amps (10 in all) just to turn the props. I opened up the middle bearing with a tapered reamer and replaced the motors and now each motor takes less than 1 amp (at 10 volts) on full power and she goes faster!

    Which makes me wonder if the solution to the problem maybe a shorter shaft to the exit from the hull and a support bearing at the prop end. You can make the support bearing housing from a second shaft and harvest a bearing from it.

    Hi Nick when you look at a prop shaft and tube they are very simple. There are bearings at each end which knock out easily and the long tube and the shaft. The shaft will probably have a thread at one end.
    If you can put a thread onto a shaft, this the most difficult part as it needs a thread cutter and a lathe. If you can source these then make your own. I found that cutting the thread as a tight fit onto a prop or u/j was the best way to keep everything 'square'.

    You need a small prop shaft and a longer length of tubing of the same internal diameter and knock out the bearings, these are to be inserted into your longer shaft. Beware as the shaft diameter can vary within the tolerances used. The rest follows.

    I have done this myself when I replaced the shaft on an old boat (not my build) when I realized the water end of the prop shaft was running on an extended 4BA thread in the bearing. It was a bit of a game finding the right shaft diameter but OK in the end.
    I can cut threads but they are almost impossible to get right without using a lathe.

    Hope this might help.

    If you look at the investment you make in time why would you use cheap woods. I always buy good quality.
    On my last build, still not finished I thought I would use B&Q small section wood for stringers on a chine hull and take it down to the required size using a 'thicknesser'.

    BAD idea!

    The wood even when steam bent does not bend evenly as the strength in the wood varies along its length.
    Just wish I had never had that idea!!!

    Hi all this maybe historical but is also current! I did a RYA yacht course in the early '90s and on the last but one day we approached Plymouth harbour in the dead of night and used 'Leading lights' to guide us in. We were returning from the Channel Islands.

    It worked perfectly, pairing up white lights and the chart showed us the direction of the next course change and then looked for the appropriate lights and it took us all the way to the mooring bouys. I seem to remember associated red and green lights to line you up.
    It was a magical night with the stars out and a it was warm and very still, never forgotten it.

    I have mentioned her on other threads but I have at last got her planing and under control. I bought some 2.8Ahr. 4/5 sub-C cells and welded up a pack of 6 to give 7.2 volts.
    The reduced weight plus a tiny 10 amp esc from Aliexpress cost ยฃ1.50, plus experimenting where the battery goes has given her a nice balance and a good turn of speed and 30 minutes plus endurance. Measured under load the power is 19 Watts.
    The propeller is a 2 bladed plastic red (P) 35mm dia. I have tried others and she will go faster but not much and this suits her fine. Also the motor is just warm with the gear reduction running at a more efficient speed.

    Attaining the discreet look of the windows with slim frames gives the right look.

    I have made a 16 inch long model and used a thick clear plastic, heated to shape screen. I then used masking tape to reveal where the pillars and frames are and theses were painted in. I used 4 or 5 coats of paint to give some body to it and let it all dry for several days and gently soaked off the masking tape.

    The paint has a solid look and seems to do the job. Construction was based on photos of various prototypes.

    Power is with a 380, 40 watt motor with a 1 : 2 gear reduction motor, consumption at speed is 19 watts. It took a long while to get the balance right for the model to plane including buying 4/5th size sub-C 2.8Ahr. cells to make up as a 7.2 volt battery. ESC is an Aliexpress 10 amp one cost ยฃ1.50. Running time is 30 minutes plus.
