Assess Structureal Integrity of Unibond Hull After Unusual Repair

Postby ttby4444 » Thu Nov 06, 2025 5:26 pm

Q1: can a Unibond hull be repaired by removing the foam from the interior of the hull, then "tab" the shell [of the hull] from the outside, then cut access from the deck, and tab from the inside of the hull?

Q2: is a Unibond hull that has been subjected to the above repair method an un-compromised structure?

ASIDE
For a winter project I found a 1975 [unidentified model and unidentified length] Boston Whaler boat [listed for sale on-line] with a trailer for $200 that clearly has significant hull problems. The seller mentioned he has the pieces of the hull that he cut out.

I don't understand what you mean by "tab". However, that really is not important.

The severe damage to the bow of this Unibond hull makes repair to original quality and appearance impossible without use of elaborate methods whose time and cost would greatly exceed the value of the repaired boat.

Q3: What would you do with this boat after you repaired it?
