Hmmm... well, I looked up theoretical boat speed... 1.34 x the root of
LWL. But, I read that when the boat leans (heels) then the LWL would
get longer, so the theoretical speed would go up right? Also, what
about the water moving. If it's going in the same direction, then that
would decrease the time you spend traveling.



But how MUCH longer does the waterline get?
Seldom more than a few inches at most.

As for the other, it's called current.
And if you are going against it, slower than the current is running,
you go backwards...
What fun, huh?
