Rutu has 3 small lockers built into he swim platform for snorkeling
equipment. It will be impossible to keep them dry so the side lockers
drain into the center one and I was planning to install a small bilge
pump. I am now thinking that a throughhull drain would be simpler and
more reliable but the drain will be only about 2" above the water line.
Any little swell at anchor will push water back up into the locker. I
have seen 1 1/2" cockpit drains with a ball float that seal when below the
water line but they are to large. Has anyone seen a similar device in the
3/4" to 1" range?
