Spray Foam Kayak Floatation: Episode 12

I've hit small rapids on a fast moving creek,in a future beach trophy 126.
It handled the water well until It lifted over a large rock and rolled.Probably since I'm not an expert.I went in the froth,
but the kayak swamped,floated for approx.1/8 th of a mile until I caught up.They do have enough boyancy.A sealed hatch in the front,and a fair piece of floatation foam in the rear sealed bulkhead.I would like to supplement that still,with more floatation foam.The more the better.

This stuff will cure with the application of moisture, but will only cure to a depth of about two-three inches. The trick to avoiding deformation and stress when filling a large void is to apply it in layers. Spray a "thin" layer (it will thicken), wait about 15 minutes, mist some water over it. Repeat the next day.

Oh, and don't try to touch this crap once you've put it in place. It sticks to anything and everything.

I tried that about 6 yrs ago on what is now called a Pungo Classic and it deformed the hull. I then had to chop it all out to get my hull back in shape. What a pain.

Now with sit on tops (I don't bother with s.i.k.s any more) I fill the hull with  pool noodles and packing material I get with items in the mail (plastic air filled bags just in case I have a hull breach.

its not closed cell foam , a real mistake
it will absorb water, you just need to get some of those foam noodles kids play with in the pool cut them to about 12 inches and stack them in the front of the hull, one noodle will float 200 lbs 3 noodles will fit in the front easy

It's freaking hilarious is what it is. It's either a joke or you're dumb as hell. That spray shit is disgusting, useless (whether or not you are rocking out whilst you spray) and horrible for the environment. Get some float bags old man.

its so when it sinks it doesnt go all the way to the bottom, I think its a good idea, if you dont use that space, like for storage or watever...

That foam is going to absorb water like a sponge making your yak heavy and sinkable...

It is a closed-cell foam.

It's the most ridiculous thing I've seen today. (and I see a lot of ridiculous shit)

Yep...

Sit-inside-kayaks have factory supplimental floatation installed in the bow and stern. Most Sit-on-tops do not. If for some reason your kayak started taking on water, it could be a problem on a SOT. We padle several miles at a time, and I would not enjoy that experience.
