But if the power boat person is more of a

seem to be so much slower. On paper at least.

There's a huge difference between an 8 kt trawler and a 5 kt sailboat.
A trawler does 200 nautical mile days almost effortlessly regardless
of wind and seas (up to a point of course). With decent weather it is
possible to predict ETAs with a reasonable degree of accuracy.

A sailboat must be managed constantly to maintain 5 kts and there is a
great deal of daily uncertainty because of changing wind direction and
speed.
