Bilge pump extension

Post by RangerTim »

When I am paddling I do not have much of a problem with water entering the cockpits of the Folbot GII, Yukon, and Aleut that I use. When sailing in rough conditions, lots of water comes in. I have yet to mod a spray deck to work with the full Balogh Rig. Problem is, the water does not pool where I sit. Rather, it tends to pool in the stern, where a pump cannot reach and sponging is a pain.

I found that with a couple of pvc fittings-an elbow and a barbed adapter- from the plumbing section of Lowe's, and vinyl tubing also from Lowe's, a pump extension can be made that fits perfectly into the intake of a Seattle Sports pump. The extension requires no adhesive and, when routed between the keelson tubes, removes water from the stern. The pump easily can be removed from the extension for use elsewhere in the boat or for storage. I use loops of velcro one wrap around the keelson to keep the tubing in place.

The vinyl tubing steps down in size from what fits the barbed adapter to what fits between the keelson tubes. I will likely make the steps a bit longer to assure each step stays inside the next, but so far it has not come apart, even without adhesive.

The pump intake and the barbed adapter both fit snugly inside the elbow. No Leaks. Still, the pump can be removed from the elbow with no trouble.

Update:

I did need to use aquaseal where the flexible tubing sections come together, to keep them together.

I made a similar extension for the forward section of the boat. While the forward section is generally drier than the stern I do pump out the bow from time to time.

A benefit of the pump extension comes when hauling the boat out of the water. With the bow ashore and higher than the stern, the stern can be pumped of the sometimes significant amount of cockpit water that has washed in while sailing rough water. Then the boat can be loaded onto a cart without the weight of all of that water.

Brilliant, thanks. Solves the problem i have wherein I either keep pumping half the water back into my kayak or I can't seem to reach the deepest part of the bilge...or both! I appreciate the details, now I don't have to buy/return/buy/return/buy return to get the sizes right. And I think Home Depot appreciates this too.
Thanks!
