Nothing too hideous in that assignment. I'd suggest that you work through one case by hand, so you get an idea of what the software is doing...
Have a read through this......
Gotta love the archives... http://www.boatdesign.net/forums/archive/t-40256.html Tim B.
Personally I'd try the easy fixes first. Then if you're still struggling, consider the more difficult fixes. Tim B.
Classic problem with transom-hung rudders. The rudder is not balancing as well as you'd like because there's too much area behind the "hinge"....
Paul, yes, I noticed. This is confused by the fact the the "downwash" from sailing boat foils and sails is actually manifested sideways, not...
Have a look at potential flow theory. Some info around on the web, it's the basis of all 2D and 3D panel methods. That should give you some...
Savitsky? Clever bloke, wrote a few papers on the subject.
Hmmm, interesting thread, and one which highlights the fact that the design work is being thought of as "Hydrodynamics and then some mechanical...
We already have a composite material that uses CNCs. It's called wood. It's good stuff, you know. Tim B.
Apply a cup-shaped object to the outside, over the hole (could be a half tennis ball). This can be done using a long pole (or possibly several...
Before we consider the rules, I think there is validity in getting an autonomous sailing boat working. As I said, there are many steps to go...

Sounds like a fun project, and there is now plenty of info around on the web to enable you to do it. So, here's the advice... Don't discount...
Yep. It's just a way of reducing the problem to something that can be solved more easily. It's applicability depends on what you're trying to do,...
I've used a plastic ball-cock (about 4" diameter) to give just a bit more time before my 14' dinghy (probably a lot beamier than your scow)...
Can you get a sufficiently good answer by setting the tension from the outlet of the chute? Obviously, the friction of the chute will make a...
Jim, A spinning propeller can be thought of in fluid dynamic terms as a volume within which a change in the fluid's momentum happens. More...
It's really about how strong the boat needs to be, and how long you want it to last. This probably depends on how old your kids are, and how much...
Given your load requirements, the solid-state-relay idea is nice, but will run into £100s each. More realistic is a triac. There are loads of...
