[Public-list] Cockpit drains above water line

[John Boor]

I have installed drains at the aft end of the cockpit and like the results.
I used the existing "T" to join them together on each side,then rerouted
the deck drains into the origional bilge and engine exhaust through hulls.
 I then installed 2 new fitting on the transom for the bilge and exhaust.
