Cockpit drains relocated above waterline

    I think I’ve read everything on this website pertaining to relocation of the cockpit drains above the waterline on the Westsail 32. 

    As I understand it, your recommendation is to tilt the cockpit floor aft and run drain hoses from new drains in the aft end of the cockpit to through hulls about 4 inches forward of the boomkin tangs, a few inches above the waterline.

    I think Jay Bietz ran his hoses from the two forward cockpit drain holes aft, along the bottom of the cockpit tub to that point at the stern above the waterline.

    My cockpit is tilted downward towards the bow.Call melazy, but I’d sure like to avoid retilting the floor if I may.

    Is it not feasible to just run my hoses at right angles athwartship from the two forward cockpit drain hoses to position a few inches above the waterline, but closer to the beam?

    Or is it crucial to reconfigure the cockpit floor to drain towards the stern and utilize newly drilled drain holes at the aft end of the cockpit floor?

    I think I’ll use Forespar Marelon seacocks and mushroom through hulls on the drains hoses,  unless there’s a reason not to.

    Thanks for all of your invaluable support.

    What I saw on one of the W32s was a 90 degree hose barb on the cockpit drain fitting, with the 1-1/2" hose running aft just under the edge of the cockpit floor to a thruhull just above the waterline at the stern of the hull.  The owner told me it worked well for him since he wanted get rid of frozen seacocks..

    Hello Mat,

    I have been involved in 13 of these modification.  The score is 11 to 2.  That is; 11 times the drains were run aft to just forward of the lazarette bulkhead, then out,   and 2 times the drains were run 90 degrees, straight out the side.   One issue is what is the easiest.  Bill Andrews, on Quest, sailed around the world after the modification and reported that there was no problem.  We ran his straight out the side.  I believe in all cases that we did not install sea-cocks.   In all cases we did not reconfigure the cockpit.  

    Good luck.  Keep us informed of the work.     Dave

    Thank to Bud and Dave  for their replies.

    With the two examples you mentioned where the drain hoses were run “straight out the side“; do you know how many inches above the waterline the through hull was placed?

    Hello Matt.   I don’t remember exactly the distance.  On Saraband the center of the thru-hull is 8 1/2” above the water.  BUT Saraband floats a little high.  My guess is that 6” above your waterline should be OK.  Just try to insure that the slope is downward a bit from the cockpit.  Good luck.  Dave
