You forget I'm a retired engineer/programmer. I did this for a living for 25 years, and
miss it a bit. I used to be doing this for $100 an hour, now I can do it for free!

See, Bobsprit, how a real troll master does it.

Your trolling efforts only result in people doing minor
work typing some insults in reply to your taunts while
my expert trolls result in people spending all night
reading books and doing math .. .. . . .


I'm the master. Bwaa ah ahah ha ha hhahaha!

The original calculation yielded 4.9 knots, so there is a net loss.
In lighter wind he has more wetted surface, and although his ultimate hull
speed may be
higher, he has to carry full sail in well over 20 knots to get there. The 20
knot
prediction leaves him at 1.2 sqrt(LWL), or 6 knots, instead of 6.3.

As neal says, math tells the truth.
