I should have said what size boats I had as I grew up.
First one dad bought was a 8' wooden pram built by a local builder in Bayville, NJ and it had a 7.5 horse Merc.
Then he bought a 10' Glaspar, same engine.
After that I had a 13' Whaler with a 20 horse Johnson.
Last one they bought was a 16' Cruisers Inc. tri-hull with a 65 hp Merc.
None of these could go fast enough to get into serious trouble. They were all perfect starter boats.
