The ISO standards for small boats do not define the depth as traditionally done, as shown in the image you have posted, but rather they define the...
As for stability, it is difficult to know without having more data, but what is certain is that you will need some fairly strong transverse beams,...
It is not easy to know how a boat sails just by looking at photographs. What I can tell you is that a boat for divers needs a platform that is as...
Thanks @Ad Hoc, I don't understand the real meaning of what you say nor am I able to analyze the depth of your thought but I can assure you that...
In my opinion, after having designed many ships of all types and many sizes, the design spiral is a theoretical concept, very useful to explain...
Frankly, I don't think the USCG has adopted ISO standards. I also do not believe that a fishing boat should comply with the regulations for...
No, that´s not correct. Even if you don't know beams theory, common sense tells you that both solutions cannot be equivalent. You can consult, for...
Maybe I should have explained the test in more detail : The tests aim to demonstrate that there is adequate buoyancy and stability after the boat...
You could reduce the distance between supports by placing intermediate supports, for example pillars. But I don't think your client will like...
Yes, but the length between beam supports is much less.
Sorry, my mistake, 0.3" is also a big figure for let's say 3 feet. Weld the plate but not on top but below the beam.
A square extrusion will give you less weight than a circular one equivalent in inertia or resistant modulus. Perhaps an elliptical section would...
Let's consider for a moment that the OP is totally serious but, due to language difficulties, or for whatever reason, he doesn't see things...
Ok but please explain why. As you yourself can see, I am quite ignorant in that subject. Thanks, again.
@ondarvr, I recognize and value your knowledge on these topics for what it is worth, of course. I immediately see when someone knows what he's...
