Overall, a very nice mod- the boats work well, models are great, and the physics are great. I'm a big fan of this mod.
However, the boats are slow. If you want to go in a particular direction and the wind happens to be in your favor, you'll go fast- but anything else and you'll be going really slow. Turning off your sail (which you can toggle with Spacebar) will make you go a little bit faster, but still not as fast (about 2/3 as fast) as the regular boats:boat! There is really not much you can do when the wind isn't agreeing with you.
If you use this mod alongside the boats mod, you might find yourself using the boats:boat more than this one for that reason.I propose something like up-wind propulsion (which happens in irl boats) - some new physics to make this a rival to the boats:boat! People smart enough to sail their ship well should be rewarded by beating out the boats:boat guys :-) Thanks for the great mod, Termos!
