We know that a cockpit full of people will squat the boat so we offer an
upgrade with positive
shut off capabilites. What we do offer are 2 Forespar 1.5 inch Marelon Ball
Valves that can simply be levered to the off position to prevent any water at
all coming thru the cockpit drains. A photo of this option is here:
http://www.montgomeryboats.com/photodym.php?startIdx=96
It is in the aft locker. For others who sail with several people and gear
(icechest. fuel tank, heavy outboard) I think having a couple of rubber plugs
shoved in the cockpit wall drain holes works well.
We offer this option (the Forespar ball valve) to everyone.
I think the design elevation of the cockpit floor is good; but nothing is going
to keep water from backwashing or seeking it's own level when the boat is
loaded with people and the associated weight of
the outboard, fuel, anchor/rode, mother-inlaw and the dog. Once the cockit
floor is below the waterline
you will have a backwash situation.
Even if the drains were in the floor and went straight down (below the
waterline) it wouldn't keep an aft
loaded boats cockpit dry. That's why I prefer to simply raise the seat on the
fuel tank locker and lever
the marelon ball valves to the off position. No water can enter at all.
