Not to mention that it is really difficult to steer a perfectly straight and
true course

Subject: Re: Stus-List Theoretical Hull Speed

 

I would like to make two points:

 

 - This is "theoretical max speed" (with the emphasis on the _theoretical_);
this means (among others) that in practice, it can be different. The other
thing is that it only means that if you want to go faster, substantially
higher force (pushing you forward) is required or that the drag grows
substantially above that speed (in short, this is the point where the
function goes non-linear). In practice this means that quite often you can
beat your hull speed by a small margin.

 

 - the GPS speed is over the bottom; the hull speed is in the water; they
may differ significantly due to drift, current and all other factors that
make your boat move not exactly in the direction you want it.
