Canting keel !

I have added a canting keel to the ELYD 50, to make it more RL-Open-50 like. The keel has to be canted "manually" after each tack, and you can really see the difference it makes in the heeling angle. As the keel is canted to windward, you also need some kind of daggerboard to provide leeway resistance. This takes the form of (again, similar to the best current Open boats) twin assimetrical daggerboards forward of the keel. The downind one is lowered while the upwind one is raised. This happens automatically as you tack.

There are still a few bugs to iron out, the most annoying of which is that when the sails are set at zero angle of attack, the boat still moves forward... not very realistic!

Oh how i hate this alpha sorting bug!!!

So the first step is to remove as many bugs as possible, and then it will be available for purchase, at a price of between 1500 and 2000 L$. Order yours now if you like by leaving a comment below. It will motivate me to finish as soon as possible!

In the longer term, I plan to do a complete overhaul of the sailing physics, as they are still based on a (heavily) modified tako script.

The wake seems to be ok

I spent most of the day today working on the wake. There is probably still some fiddling to be done, as the bow spray doesn't quite look the way i want it.

Here we are fully powered up going downwind















And going upwind

It works !

At last, i managed to get my boat working... It uses the old tako script available on the lsl wiki at the moment, but i modified it heavily. The first important change is the fact that it uses apparent wind to sail, which the tako wasn't doing, ie: it wasn't taking the boat's own velocity into account when computing the wind. And secondly I have added an assymetric spinnaker, which is still a bit buggy at the moment, but should improve as time goes on...

The main problem with it is that I took a giant sphere prim as a base, cutting it every which way to get a proper spinnaker shape, but as the cut away part is underwater, it touches the bottom or land closeby and blocks the boat... Making it phantom doesn't seem to help... Also, the sphere is hollow, but still pretty thick, so the inside and outside textures are visibly separated, which is annoying visually...
