Bilge pump set-up for a Kayak

I was researching this awhile ago, i know the Boston Whalers have foam and are pretty much unsinkable. I read that once you have a leak, the foam makes the boat incredibly heavy due to the water.

This is why i have not done it. I am not sure if i want to be hauling a kayak with drenched foam.

I am pretty ignorant regarding this whole foam in the hull thing.

When I was in the Coast Guard we had an old Boston Whaler wash up on Ballast Point one year after a storm. No CF numbers so they could not trace it. The base used it for a tender to paint the 82 footers for years. When the 82's were finally sent to the scrap heap the base commander looked to get rid of the whaler all beat up and cracked, and I volunteered to take it. I rebuilt it to new condition, but it took routing the chines and keel front to back down to the foam, and it sat draining and drying out for over a year.

Yea, I think the pool noodles are a much better idea, as it is not permanent.

If you use a closed-cell foam, the foam itself will not take on water. You can get pourable closed cell foams that could be used to custom fill your kayak hull, rendering it effectively unsinkable.

the hull truth is probably a better resource than BWE for extensive discussions on the merits of various foams.

I really need to re-think this whole bilge pump placement idea.


You need to have a switch to power the pump close enough to you. If you are flooded and you move your body weight forward or back, you're also moving all that water in your hull. (say hello to the titanic again)

You also need to make sure that your electrical connections are watertight. The last thing you want to do, is turn on your pump and your battery is under water and you connectors have fallen off due to the electrical corrosion of the salt water. Those two way trailer connectors will FAIL.

And if you do pool noodles you want to make sure you are floating enough to make sure the manual bilge pump is effective.

The whale pump does seem ideal, if you can pump, rudder steer, and pedal all at the same time. Alot to think about when the worst does happen. I am tired even thinking about doing that...

Right now, i am thinking about an automatic bilge pump connected straight to a battery with a one way valve, but the battery would have to be above the water line. (I am still planning it) (maybe strapping the battery right under the hobie lid will work, since the bilge pump should technically pump the water before it gets to the lid) Everyone on this site has their opinions, but i want to know which ideas have worked during the worst case scenario, not the what if scenario...

A scared man with a can or bucket can move more water faster then most pumps. Very simple, find bucket which enters and exits hatch easily, then keep it handy for emergencies.
