Even with the warp ability it feels like you still have to do a fair amount of sailing because the warp locations are fairly spread out. I can see double speed helping considerably, though.

Thinking on in some more and I guess another problem with the sailing for me is how often I had to stop and play the wind requiem. It really makes navigation a chore. I could see a mod that lets you change the wind direction much more quickly would help tremendously (maybe there is one, I have not looked).
