water-logged flotation
Have a 21', center console, fiberglass sport fisher, made in 1972.
Another post mentioned a chemical way of removing foam, and others mention cutting out the old foam. Cutting doesn't seem practical, the entire deck would have to have access holes cut all over. Anyone know what chemical method is available, if any? Many thanks, don. |

Rocking and rolling the boat. Whatcha gonna do with the effluent? Terry K |

Probably be cheaper and easier to get ahold of another old hull, that is dry. They are all over the place, many with trailers and even decent motors. Once the foam is soaked, short of a skin strip and rebuild, the tool (boat) has probably outlived it's time. Like any tool, maybe if it had been better tended in it's younger years it might still serve you, but this old boat probably won't. Just my opinion. |

wrote stuff and I replied: This also pends on the foam. Urethane will not GID about acetone IIRC. However, WTG with effluent would be let it sit till acetone evaporates and then get rid o remaining "stuff" at the tip...no worse than a bunch of foam. Acetone. Gallons and ginallons.

water-logged flotation
Urethane foam is a potential problem in marine use as it is not closed cell
and therefore will, over time, absorb liquids. It is popular because of its resistance to acetone and other like solvents. Unfortunately, there is no way, other than mechanical removal, to get rid of it. As your boat is small, I suggest using a sawsall or a large flex disc, remove the entire deck. Turn it upside down and remove the inner liner and foam to destruction. Repair the offending water leaks, which caused the problem in the first place. Then refoam upside down leaving the deck margin clear for rebonding to the hull. After the foam is sanded straight to the original dimensions, then layup the new inner hull liner on top. Rebond the deck to hull margin, patch the bond space at the deck margin with additional foam and reglass the hull liner on top in the previous manner. The job will take 60 days part-time. Steve PS I have done this on a 21' trihedral hull on the entire port side and it was very successful. It is not as difficult as it sounds. Keep in mind that the deck shape will distort under gravity upside down when the foam and inner liner is removed. So it is important that the deck is fully supported by shims and wedges before this process begins. In that way, its shape will be retained. "don" wrote in message ups.com...
