I guess it depends on the local climate, if theres gonna be snow and
ice, covering is probabably
a good idea. Snow in the cockpit will pack the drains and turn to ice,
allowing the possibility of
a great deal of wieght from water biuld up in the spring when it rains
but doesn't get warm enough to
thaw the drains during the day, then at night the whole lot can freeze
up and maybe be a worse problem
the next day ....

I agree that a cover is a good idea, however, I think that ventilation a
necessity.


It probably depends on the local climate. Last year I left two ports a bit
open. No rain got in, and for the first time ever, I got no mould.


At a recent boat show, I saw a solar powered ventilator. My next boat
will have one.
