Rebuilding a 11 ft whaler needs some work. One of the things needed is to fix an area which requires a little foam. What foam is suggested to use. The boat is a 76 whaler. Thanks John

Here is a
LINK to a good foam company I plan to use on my 19 project. It is a standard two part foam - reacts quick so be prepared to pour. I am going to use the 2lb density foam. You could go denser but you just add weight.

To match the original density I think you need to use a 3 or 4 lb foam. I would consider the volume you are replacing too.

the original density is 2lb foam and it's what whaler recommends for structural repairs.

modenacart,
I will agree that the original 2lb foam is not allowed to rise and may in fact act more like 3lb foam but you can never duplicate that outside the factory. Whaler recommends using 2lb foam for large structural repairs.

Thank You for the help. I will use #2 foam for my project.

If you read the article, it states to use 2lb foam to create blocks to fit into the hull for the repair. I don't know why you would do this when you can use a 3 lb or 4 lb foam that is rated for structural use that you can glass over and get a much better bond.

Clearly the 2 lb foam is not recommended for structural repairs. In the boston whaler hull, the foam acts as part of the structural integrity of the hull.
