I'm considering drilling a hole in the hull!!!
I have an anchor locker in the bow of my Ocean covered with a hatch.
The locker does not have a drain because the only place it could drain into is the sealed void under the deck.
Obviously after using the hook the water drains off the warp etc and forms a puddle in the bottom, I then have to remove the whole lot from the locker to wash it off, and sponge out the locker with fresh water.
A friend with a hard boat has a similar locker, but with a drain drilled through the hull and covered with a natty stainless splash guard.
After using his anchor he just runs a hose into the locker to wash the salt out of everything, and lets it drain out. Then of course washes in all out properly and lays it out to dry every other month to check the warp.
The 'hole' would be well above sea level when at rest and any water splashing in ploughing through a wave would soon drain out again.
Even if it did fill right up its only small anyway.
Does anybody use a drain like this from their locker, and had any issues with it?
