I Sailed all the time as a kid, grew up on the water in Denmark. got a pilots license in my early 20's and was an instructor. Not much work at the time so I sailed again, started a small charter company, thought sailing for a while. Got back into flying in the late 80's and have flown wheels, skies and and float. And is now again looking at a hole in the water to throw my money into. (never learn)
Life is to have fun.
A sail is just a vertical wing (pretty much)
