Ive heard that ODay models have a void in the bottom aft of the keel. Whats the story with that?
Rumor has it the ODay builders, anxious to lay up the next boat, would pop boats out of the mold before the fiberglass cured, and then stand them against the wall on their transoms, resulting in the void. While a fair bottom is always faster than an unfair or bumpy bottom, Rhodes sailors acknowledge that, when you consider the extra weight of the material used to fill the void, it can be a wash.
