I was thinking of kevlar on the outer layers for abrasion resistance, at least on the underside of the hull. Though, this might bring up thermal...
Thanks for your reply. I know there is no magic formula which is why I was asking what the industry has settled on for a typical hull thickness...
I got too much time on my hands due to the virus situation. So I'm toying with trimaran design. I have a couple of questions. First, there seems...
I was playing around with Free!Ship and I noticed it reports the Cp for the forward half of the hull and aft half of the hull along with the...
Since tris routinely exceed their hull speed by a significant margin, doesn't that mean an adjustment to Cp is needed or do you go ahead and...
I'm having a little trouble finding guidelines for the prismatic on the main hull of a trimaran. I've read you treat the main hull in much the...
Yes, a 2D flow isn't going to work here since it's in effect an extremely low aspect wing. Though with most wing profiles, there's a pitch down...
The hull is intended for use as the center hull of a trimaran. So a balance needs to be achieved for light wind performance and more powered...
I'm probably misusing the term transom. I'm referring to the aft section of the hull below the waterline leading up to the vertical portion above...
Yes, I know waterlines and stations would have been more helpful. But as mentioned, the modeling program won't generate those. They have to be...
I don't know if these pics will help. I'm using Blender 3D to sketch a hull and it doesn't know what stations, butt lines, and water lines are....
I'm a little confused. I have a transom sketch that is flattish and tapers upward to the waterline as it moves aft. The upward slope starts around...
How about a narrow front, round mid, and a flattish aft hull tapering back up to the waterline. From what I read, the asymmetry fore/aft helps...
That is a beautiful trimaran. Very graceful.
Umm, wrong boat. I was referring to the kayak being paddled by hand in the picture below the proa. (Guy in red Yamaha life jacket.)
The picture posted above of the kayak-style boat posted above is a good example. The boat I'm sketching is a modified blue-water trimaran form...
Actually, I'm thinking just a bit bigger. (45ft +/-)
The anti-dive paddle seems good at first, but as mentioned earlier it might work against you depending on the angle of attack against the water....
That's the same idea, but a different culture than I remember. I've been sitting here thinking about and I'm guessing the same effect can be...
I can't find an example pic, but I remember seeing some Polynesian outriggers with horizontal spade paddles on the bow. They were pitched up with...
