Boat Foam

So... Whats up with the boat foam? Sprayed all up under the sides of the Shell. Nasty and Falling out all over the place.

I understand that if i am not upright, no displacement means no float, so is the foam intended as a last line of defense in case you tip?

Can I just get rid of it? Tear it out?

If not and you think its worth having, How can I get it to stick back up there?

Can I get new foam? How do I do that?

The intent was to keep the boat from completely sinking in a catastrophic event. You can take it out and put a truck inner tube up in the bow. There are 2 part foams designed for boats and flotation, Crestliner boats don't have enough flotation in them so they are sending Versa foam to fill in under the floors and other areas.

Some ugly stuff huh? I think having it static electricitied to my arms on a hot sweaty day of boatwork is worse then fiberglass. I didn't hesitate to cut it out in chuncks where need be, Bill

Alright, so Im gonna use a can of that construction foam to "Glue" it back up in there. If that dosnt work, ill just toss it I guess. Ill try no to tip the boat over.

It was put there (in the high spots of the hull) to stabilize a swamped boat. Without it, it will roll. I took mine out for the same reason and filled the bow foreward of the footrest. At least mine will float bow up. Easier to attach a tow line. :up:

I would suggest some floatation. I like to fly my boat. I don't plan on sinking either but plan for the worst and expect the best. :boating:

Most every damaged Stream I've seen sunk anyway, especially when the deck comes off. The "newer" ones may be a little better, since 1980 or so, the Coast Guard put in the upright flotation rule, so they may be a little better.

Boats from the 1970's didn't float well after an accident, and in the newer ones, the foam is frequently saturated or removed.

The best policy is not to run alone. If you wreck the boat, and the deck stays on, they will usually hold enough air in the bow to float nose up for awhile, so the chase boat can recover the damaged boat and driver.

There's no future in hoping one of these things will float after an accident, the odds are not good.

Yea, I cant imagine that foam holding up the V6. Anyways, What kind of product do I want if I want to spray my own foam? Is there something special? Does it come in a can, or Do I need a fancy Mixing Gun? How do I do it.>?

The foam is sold in cans in 2 parts. You dump the 2 liquids together, and it blows up into foam (pretty fast).

Hmm, so then how do you get it in the upper part of the deck? Do you have to turn t e boat upside down and pour it? I imagine you would need a spray gun that combined the two chemicals as it was spraying.

What if you simply had two spray bottles (like old 409 bottles) and simply sprayed a thin layer of one chemical, hen sprayed a thin layer of the other chemical on top of it? Would it mix and expand? Anyone tried this?

Its nice to see its cheap at least.
