Closed cell foam in a Lund Fury 16"

[Fury2]

After a great deal of research and great input and ideas from those of you that know, I have a better understanding of what to do for replacing the foam in the hull of my aluminum boat. I was already to order the 2 part foam on line and then I called a local foam installer and he said he could spray my compartments w/ 2 1/2 lb closed cell foam for $800.00. I can buy the pour in for around 130.00. I figured I need about 16 cubic feet. Is spray closed poly foam ok? I am having a hard time w/ that price for the spay but I understand the pour in is a mess+ hard to work with. I am fairly handy. Any ideas.

I wouldn't pay $800 to foam your boat. Its not a hard job even if you use the pour-in foam. Just block off the middle section (along the keel) so you can preserve a drainage channel back to your bilge JignRub has a picture of his boat that depicts this set-up. He might swing by and post it (if not, send him a pm).

Just make sure you got good temps if you are using the 2 part pour-in... In cooler temps, it doesn't expand as much.

You can also use the pink or blue foam sheets, I spent 150 bucks on my foam:

$800 is outragous! Depending on where you live, I'll come install it for $500.

Your boat will be an easy foam job, real easy. Your biggest problem will be temperature to get the full rate of expansion, between 85-90*F... but it will still work, it just won't expand the full amount.

All you have to do is block off a drainway down the center of your boat with some plywood or even cardboard will work. Then pour the spaces in between your ribs one at a time. Pour the spaces so the foam expands higher than the rib, then come back with a handsaw and cut the foam flush with the top of the rib and put the excess you cut off in the bottom of the next rib space and pour foam on top of that. you'll have very little waste when you're finished. After you've got everything poured , remove the plywood or cardboard from the drainway and you'll have excellent drainage to your bilge drain.

Your drainway will look something like this (but probably neater):

You'll install and cut the foam like Sleeper6 did in post #12 of his build:
