In order for these drains to function well when sailing the port drain should be connected to the starboard through hull and the starboard to port, as Rugosa noted in post #6.

Hmm..pricey little buggers! I'm wondering if an RV equipment place might have smaller drains than what might be found in a hardware store? I haven't measured my drains yet to see what size I might need. One post suggested crossing the pipes to the drains to the opposite side thru hulls, but if I do that, I wonder what will drain the bilge area of the boat? any thoughts? I have a hand bailer with a hose that looks like it might have been attached, but I'm not sure to what. Thanks!

I'm not sure what you mean by the bilge area of the boat.

If the drain hoses are not crossed the leeward drain can allow the cockpit to fill when heeled on some boats. Crossing them prevents this.

Thanks. If these two cockpit drains are cross-connected to the through hull drains, what drains the bilge/lowest area of the boat? An auto bilge pump? Or is there a drain I'm missing? It's hard to believe that the pupose of the thru hull drains are just to drain the cockpit area alone. Any thoughts? Sorry, but I'm new to this, obviously.

The bilge area under the cockpit well is below the waterline - it will not drain and a bilge pump will take care of it. If the cockpit well does not drain to the bilge (it shouldn't) and the drain fittings we are discussing are sealed properly there should not be water in the bilge in normal circumstances.

There's about 6-8 inches between the cockpit floor (sole?) and drains and the thru hull drains. One for sure, is connected directly to the drain with a rubber hose and two clamps. I get some water in the bottom of the hull from rain, etc. behind the current thru hull drains. I was assuming that the bottom hull of the boat where the thru hull drains are is the 'lowest point' of the boat, and thereby also collect in leakage, condendation etc. which then drains out. Maybe the whole hull interior should be (ideally) always dry, so any hull drains aren't' needed except for the cockpit? Does that sound right? I'm new to this--on smaller boats I had a bailer which I would flip open to drain the cockpit while sailing, and then close down again.

Small sailing dinghies have bailers but larger boats don't. With a hull that is in rather than on the water it is designed to drain the above waterline cockpit well through the fittings in this thread. The lower bilge is taken care of with a bilge pump, either electric or probably manual in your case.

Always better to go with the real deal marine fittings, especially if in salt location, if $$$ is tight look for a RV or bar sink drain assembly as they should be cheaper. You have two cockpit sole holes/drains each of which must be connected to a thru hull, you should also have manual and/or electric bilge pump to service the bilge area. Area below cockpit sole likely getting water from disconnected scuppers and/or deck leaks. Every hole is potential water access. Sooner or later all deck fittings need to be rebedded. Hope this helps.

That's interesting about criss-crossing the hoses. It makes sense. Now I'm going to look at the scupper drains with the 90 degree hose connection.

Thanks for the information. It gives me a better idea of what needs to be there.
