Maybe I should look at the beam more carefully as well as the overall length. Regarding my dilemna. A Rustler 31 looks a better bet than a Nich 32 Mk10. This, of course, is all other things being equal type of thing.
I wonder what the best, cost effective dimension band is in todays marinas. From what I see, the big boats may cost more but are better value on overall length but get zapped in marinas which calculate volume L x B.
