My Burn's-designed Golden Gate 30 has about 3-1/2-inches clearance from the bottom of the
galley sink to the at-dock waterline.
What is the best way for drainage
overboard?
1. Direct flow through a seacock and thruhull under the sink. I tested and get a fair amount of
water into the sink on starboard tack so the seacock would have to be closed while under way. The orginal owner (who built the boat) abandoned this after the first
cruise and built a sump (under the
engine bed).
2. Drain into a seperate sump which gets pumped
overboard via a small auto
electric bilge pump. Potential
odor problems (but a trap was not used). The original owner was not that please with this either and I removed it for that and other space considerations.
3. Direct feed to a macerating
pump and overboard discharge. This seems like a good solution - no through-hull, no stinky sump (there's always standing water).
Am I overlooking something? Have you, the sailing masses out there, tried or used this?
Thanks ahead for your input.
