    I wandered onto this forum a few weeks ago partly out of curiosity and also partly because I wanted to have a chat with people who have an interest in boats. I have lurked in other threads and such and it is obvious to me that there are a huge amount of very knowledgable and experienced people...

    Yes, it is probably easier in the States, but most of the facilities over here are either too expensive The following is hard to admit because you have been quite cantankerous - sorry to be negative and I am sure you are probably a nice chap with a huge amount of knowledge. However you are...

    So you end up with more joints? Pretty much as I originally said in post #3420…

    Yes, I know. I did infer in my original post that I was not referring to large facilities Or dedicated individuals who have the time to do really beautiful forming. This is the problem with people taking stuff out of context from earlier posts. Yep, but the physical realities of trying to bend...

    Ah the royal ‘we’ statement. As I said it can be done and I know it is done. But for most small facilities or amateurs, it is either too difficult or too expensive. So there are many boat builders that reduce cost and time by not making compound curves.Taking my statements out of context so you...

    Launched as a monohull at first due to width of locks on the river, then it became A trimaran. Hull was a chimney or industrial cooling tower from a hospital.

    Yes you can curve very thick plate to make round bilge and yes it is a PITA. I have done it. I have even made simple round curves in 6.3mm plate. Compound curves are another whole issue as to compound curve, the steel needs to be stretched. This can be done in massive English wheels, but they...

    Bit confused, as this is not unknown or controversial. if you are building a boat from sheet material like steel, Alu or plywood as thousands of people have done including Alubat: https://www.alubat.com/gammes/en-ovni/ Then you can not do compound curves as in concave or convex shapes. In steel...

    Yes, with sheet material, it is quite difficult or impossible to do complex bends, one way around that is to use several pieces with joints. However there is a limit to how many you can do, so most do what they have done below:

    Very true, quite hard to build a plane from your own design. However even with Vans Aircraft, the firewall forward is mostly up to the builder. I built an RV6, fantastic aircraft, the big problem I had was with the engine. It was a Superior and Superior had used the wrong sump on the carb...

    You really think that Volvo stick different cranks in their penta engines? You really think Mercedes OM615s in boats have special cranks? Cranks cost a lot of money even when in large production runs and why would a marine engine need a special crank?

    Lagoon 450 18mm ply bulkheads… Even production boats with Naval Architects mess up. Building a one off boat will always throw up challenges.

    That is why I just spoke about the hull shape. Some of the other things are obvious and some may just be YouTube. As for your second sentence, you may be projecting there a tad.

    ChatGPT answers the anchor sizing question once and for all

    It maybe laughable now, but unfortunately as it gets better it will be able to do stuff that we simply will not be able to do. It will be able to process huge amounts of data and make links that will seem to almost predict the future. Just look at how simple algorithms have already driven our...

    How do you know he is a qualified naval architect or a good one? Not saying he is not by the way as I do not know and did not read the posting, but it seems to me that anyone can claim anything on here. I personally would not feel comfortable stating a solid position without recourse to solid...

    No idea where you get that from. I worked in the marine industry and marine environment for quite a few years. Yes I use marine winches, blocks and some nav gear. But I made my own hatches, cleats, mast and such because I could and in some cases because marine stuff was not the best solution for...

    Well I was answering the point someone else had made about officially certified marine materials. My point about project management was made in answer to the comment that others had built boats and they had no issues or failures at all. I find that hard to believe and since you have built a boat...

    True and people all have a different appetite for risk, but I am not convinced by the bad hull shape bit. I have been messing around with my hull shape, I have played with bulbous bows and it is quite surprising how much you can do without affecting speeds or general efficiency. A lot of steel...

    I am unfamiliar with officially certified materials for building recreational boats. Marine ply has some certification and I just paid a hefty price for it, actually it was for my car. Lloyds certify ships I know and some materials, but this is not like aviation and FMA stuff. There is no...
