Cockpit Drains: Where do we get them?

Here's one I've not seen and don't find on a search of the forum: Where would one get a drain for a cockpit? I have a 1970 Newport 27 with two drains forward in the cockpit, starboard and port next to the companionway. They appear to be about 1 1/2" with a hose attached below the cockpit to drain into through-hulls. They look a lot like a standard sink drain or very similar.
At the stern, the cockpit has a lower section, about 12" long, the width of the cockpit, and 6" lower. It has a very small drain, about the size of your little finger, which has a small hose that drains below the cockpit and then out the transom. As you can imagine, it is easily clogged.
I thought about getting a larger drain and attaching it to a larger hose and draining out the transom as well. But...and here's the question-where would one get the actual drain assembly? I can't seem to find one. I just got my new 2014 Defender catalog and no such animal.
So, since it's cold, I've nothing better to do until I can unbury the boat from the snow, I'm on a quest for a drain.
Anyone got any ideas?

Re: Cockpit Drains: Where do we get them?

My Pearson uses something like these for cockpit drains:
Perko 0285DP | Fisheries Supply

and these in 1" for deck drains:
Flush Head Marelon Thru-Hull - Fully Threaded - Forespar | Fisheries Supply

Defender has them too if you search for cockpit drain:
Forespar Marelon Flush Head Deck Drain / Thu Hull with Screen

Since all of these are flush/recessed you'll probably need to do some core removal and fiberglass work to make a nice recess for the drains.

I'm no longer participating on SailNet.

Re: Cockpit Drains: Where do we get them?

Sorry to take this slightly off topic.. but this is pertinent to what I have been pondering with my Seasprite.

The 23 has 2 cockpit drains, both forward that drain straight down to thruhulls far below the waterline.

I have been pondering removing all below the water thruhulls and just running these two lines back under the cockpit and through the transom. Any thoughts?

We did this on a former boat, whether this will work depends on the boat's configuration and the location and slope of the new 'drains'.

In our case unfortunately we ran the drain from aft in the cockpit out under the counter (the actual transom was too high) and we discovered that when heeled the stern wave caused water to backflood into the cockpit where previously it had not with the thru hull drains. In retrospect crossing the drains over side to side may have solved that one, had there been room to do so.

On another boat I've seen it done, but with poor slope leaving a low spot that stayed full of water - it froze one winter and split open. However since it was all above the waterline the only water that got in the boat was rain water.

Anyhow, the upshot is that while it sounds a great idea, how well it works depends of the relative locations of cockpit floor, transom elevation, hull shape etc.

Maybe get a cutaway profile drawing of your boat and do some sketches first.

Re: Cockpit Drains: Where do we get them?

I just read an artiicle where they moved the drains thru the transom using schedule 40 PVC. Looked great. They had used hose to connect between the deck and the transom.
Tons of plumbing parts that fit this application.

Back in the day they WERE sink drains in lots of cases.

True... and as long as they're a decent stainless and not pot metal they are probably OK - the issue was usually lack of a good hose barb or a long enough spud to firmly attach a hose.

On the flip side, if you saved the basket/stoppers you could turn the cockpit into a bathtub for toddlers on a hot day!

Re: Cockpit Drains: Where do we get them?

Try a plumbing supply house & ask for a straight grid strainer. Be sure to get something made by McGuire. It'll be heavy duty & not made from white metal.

I'm not happy unless I'm complaining about something.
I'm having a very good day!

Try Dearborn Brass | Oatey look at the polished brass bar strainer. our 1979 sabre 34 used these drains as cockpit drains. there are corrosion issues you have to be concerned with. I ended up using a perko cockpit drain/ the Chrome plated cast bronze body with brass screen
