Re: what kind of board for a beginner/intermediate windsurfer? go?

Rob, have a look at :

http://www.lbwindsurfing.com/

Good advice on longer boards there, from an experienced crew. You need
consider larger volume for Lake Ontario (flaky wind). Even Kingston I
have found rather average the last 2-3 years. Nostalgia is not what it
used to be...

I find many shops dangle at beginners the macho thing ("I'm into
speed, buy short, planing is the only thing"), regardless of the your
actual needs and inclinations. Actually the sales guy often stares at
his own muscles as he talks to you.

Again, unless you want to start the sempiternal quiver, start longer
with dagger, play around 1-2-3 years.
