Not to get into a measuring contest, but I dive in New England waters year round. Wet and dry.
Oh yeah! Well, I'm too much of a wimp to dive wet anytime of ye.... Nevermind, I'm losing that measuring contest!
To the OP, honestly it has never been an issue. I've never felt pushed forward waiting for a boat. The only explanation I've heard is that this is often (I won't say always) due to overweighting.
