How many drains
I'll install drain/s in my cockpit (my project it is 36' Spray with
wheelhouse). According to ABYC standards 2" drain is required. My question is what is better: - one 2 inches drain or two 1 inch or two 2 inches or .....any other combinations? - straight down bellow LWL or with an angle above LWL? Thanks Adam |

How many drains
Adam,
I used 4-1.5" drains, 1 in each corner, cross connected below to a 3" ball valve below the water line. Suggestion, use a drain strainer like in the kitchen sink along with the rubber stoppers. This way the cockpit can be used as a bath tub or utility sink. When doing the cross connects and turns are required, use TEE fittings with a pipe plug in the unused direction for cleaning in the future. I used TIG welded aluminum tubing with hand made TEEs. These pipes are installed with an angle of declination. The connection between the cockpit sole and the plumbing is done with 3" hose sections for flexibility. The large Thru hull not only drains the cockpit, but the showers and sinks as well. This limits the number of thru hull openings. Steve "Adam" wrote in message ...

How many drains
Take whatever the ABYC standards recommend and match it for cross-sectional
area. You can use any combination of drains you want, in any shapes, as long as you meet or exceed the cross-sectional area of their round drain requirement. Also read the section on draining time. Sometimes this increases the drainage requirements. Brian -- My boat project: http://www.advantagecomposites.com/tongass "Adam" wrote in message ...
