Cockpit Drains

[hinmo]

I think a lot of guys have installed rubber flappers on the transom over the scupper holes. They prevent, to some degree, water ingress into the scuppers but will allow water to escape. Flappers probably isn't the correct name, but  you get the idea. I think I saw 'em on a photo of Skips boat.

Got em on my boat, they need replacing (old, cracked). Had em on previous boats and they haven't worked well.

I will need to get some exterior transom plugs in case the tubes leak, wonder if the flappers will allow plugging as well.

I have replaced the flappers twice over the years, next time I will remove rubber and not waste any more money on something that really does not work on the CP16......nies

I describe my adventure with a broken cockpit drain.
The quick fix was to simply insert the transom "cork" into the drain.

Good point.  Just like I have wooden bungs tied to each seacock on my big boat, I should also have corks ready to go for drain emergencies.  Will do.

Hi, my boat is a Legacy, so pretty much the same as a 16, and it comes from the factory fitted with "flappers" and I don't get much water back up the cockpit drains. This is with a 90 kilogram sailor, 25kilogram outboard plus fuel etc.
On my boat the cockpit floor is always wet because of the water which comes up the centreboard control line. So, is a wet cockpit floor a problem? Well, on those dream sailing days, drifting down wind, yacht vertical, glass of chardonnay in one hand and a ham and cheese baguette in the other, steering by casually leaning on the tiller, I can imagine that a wet cockpit floor may be a problem.

However, beating hard to windward in twenty knots, boat crashing into the sharp three or four foot waves that my favourite sailing lakes throw up, spray everywhere, boat heeling till the toe rails are submerged, frequent solid water crashing over the bow, me soaked to the skin, in these conditions the cockpit floor is wet as is everything else. But in this sailing scenario (which has been the majority of my sailing recently) a wet cockpit floor doesn't enter my list of concerns. The drains work well to remove most of the water quickly, that is the prime concern.

So, I suggest you try the flappers as fitted to the Legacy by ComPac, they are probably available from the company.

Don't know about the 16, but the Legacy has a partial bulkhead about eighteen inches forward of the transom, the top this is well above the waterline, so if the drain pipes broke, as has been mentioned here, the maximum amount of water flooding in would be limited to a couple of gallons. Not enough to worry about, repair when you next get ashore, no need for emergency plugs to block the drains.

Cockpit drains???  What are these strange things that you speak of?   Mine seem to be missing on my Eclipse.....

Eagleye,

Lovely picture of your Eclipse. That certainly is a large cockpit drain, can't imagine carrying a cork or plug big enough to block that!

Cheers.

Thanks, Pete. 
It sure makes it handy to rinse out the cockpit after lunch.

I use these and they work great. Flexible, well constructed, easy to get in and out and easy to see. I have a 1976 CP 16.

Where did you find these plugs?

[Sterling]

I purchased mine locally at Bill Jackson's, but you can also get them online.  I own some kayaks so I originally purchased some to plug the scuppers in two Hurricane boats.  They are sized by color, meaning the red plugs are the largest and the green are smallest.  My kayaks take red, my CP 16 take yellow.  I had tried some other ideas first and even went over to Hutcins in Clearwater because their parts list showed scuppers. Turns out they were plugs like the ones used on motor boats.  The sink or tub drain plugs work, but changes in pressure can make them pop out.  These scupper plugs are perfect!  Again, well made, which you will notice if you get them.  If I take a wave in the cockpit, I will still easily see them and pop them out by the attached cord in an instant. I have no safety concerns.

Amazon has them. Search under "Ocean Kayak Scupper Stoppers"

Which of the four sizes of yellow do you use for CP16?...............nies

[Sterling]

There is only one size yellow.  I know they show a size chart, but they will send you the color that goes with the size you select. Again, I bought mine at Bill Jackson's, but I believe you would be ordering the "small" size to receive yellow. You could send a message to the seller to make sure, but I'm 99% certain that red is large, blue is medium, yellow is small and green is extra small.

Nies,

check the Amazon reviews on the scupper stoppers, the following comment with plug sizes might help?

This review is from: Ocean Kayak Scupper Stoppers - 2 Pack (Misc.)
With no reference to sizing, good luck finding the right size... on other, non-amazon, sites I found chart that told you which one fit which ocean Kayaks but left no actual sizing information if one wanted to buy these products for other kayaks. The fist scupper plugs i bought of a different kind were way to small so I got the large in these. They were way to big so I keep buying the next smallest size and I guess the third time was the charm cause the "small" fit but with a good portion of the plug sticking up so I went a head and got the x-small to see if they fit more flush. Long story short I enjoy them now, I just wish the manufacture would be more straight forward in the sizing information. So no one has to play this game again, here are the sizes I found them to be. Each one has a slight tapper to the bottom.

Large- 2"-1 3/4"
Medium - 1 3/4" - 1 1/2"
Small - 1 1/2" - 1 1/4"

Also, the bottom of this PDF confirms that yellow is "small".
