another foam question floats to the top

[nigelbear]

I am restoring a 1957 aluminum boat and and am trying to find the hard, block-type foam. Does anyone know where to find it, or should I just use the styrofoam blocks that I see under floating docks.

Re: another foam question floats to the top

There is an existing foam. You buy it as a liquid in 2 Components and mix it and poor into your Boat. You have to be very carefull, it extends around 20 times.<br />Also this foam is resistent of fuel. But when you poor fuel al the time on this foam it does harm and and loses the floating feature or worse, your Boat becomes to a dangerous gasoline Bomb.

2-lb is commonly used. 8-lb is the hard stuff.<br /><br /> http://www.uscomposites.com/foam.html

4lb foam seems to be the norm around here ive noticed.has good rigidity.good structural for boats as well as better resistance to absorbing moisture than 2lb and lighter than 8lb.you can buy block foan but would have to open up your boat to install it as well as do alot of cutting and shaping of the foam in order to get it to fit.then you will have alot of voids and gaps because you cant get to them easily.not to mention the mess and time spent on it.i would suggest going with a 4lb 2 part foam.thonk it will serve you better.good luck. well have to edit post here.re read an seen its an aluminum boat.in which case i personally would go with a 2lb foam.aluminum being lighter than glass and more rigid.block form would still be a pain

The boat only had the blocks under the 2 bench seats and the storage area behind the back seat.<br /> I have the boat stripped down to bare aluminum and can access the floor very easily.<br /> The water needs to flow through the seats and the 4 aluminum support braces to reach the transom area.<br />I could build a bunch of tubes to link the support and seat drains and then pour the foam, but I was thinking it would be alot easier to just lay the blocks between the braces.<br /> <br /> http://groups.msn.com/_Secure/0SgDOAskVqhxMRyUbSTS5M51kGCvXJq9Qi8dQ5wLO5sElzP*eRMkJ0Q*jXuwmVryk0eLrd1lkGUdz4OtZJqJo*5S3BD*V*cmodRqDlktL44kx7tfG!5veaw/1950-4.jpg?dc=4675451973085484 721

Re: another foam question floats to the top

so there is no flotation under the flooring at all?in the photo looked bigger that i had expected.would think you would have foam under flooring.but if its only in the 2 or 3 areas i see no reason why you couldnt use block foam with satisfactory resultssee if i can find that link again here. it floats it floats this should help they have billits as well a pourable.

Re: another foam question floats to the top

Thank you for the link.<br /><br />The only raised floor that it has is right where the spare tires are laying in the pic. The rest is the bottom of the boat. The foam was under the 2 bench seats and from one side to the other under the tires and storage hatches. (after that it drops off and is open from there to the transom)
