Like the other thread says looks like the gel has come away from the lay up , or the layers were never bonded properly . Does this happen when you dont get the whole thing done quick enough , or the resin mix is wrong ?

Isn't this boat made with a balsa core/ sandwich type hull ? , but most ( all) RIB hulls are solid ( ie no core) - the stringers & runners may be cored but not the actual hull ?

Makers do please tell ...................

We use balsa and foam in certain areas of a hull - the blame seems to be blamed on vacuum bagging, and delays in laying up the layers. Using more sticky resins and keeping the time between layers to a minimum will help prevent this.

At BananaShark we tend to use the resins that stay sticky for a long time as we produce more race boats than anything else, and they often need collision damage repairing and these resins allow a chemical bond months or even years later.

We use foam longits in our leisure and race boats as well as wood, and they could suffer from the same fate internally if not bonded properly as can "matrix" type stiffening used in some boats sold in the UK, and some of that is stuck in with Sikaflex type goo!

If any of our boats has a failure such as this you would get a new hull inside 5 years - although this doesn't apply to race boats, we would still come to an arrangement!

My first reading of this was that it would only take you 5 years to come up with a replacement!

good repairer could do it, i had an old avon 725 that had delaminated completely down one side, we repaired it about 8 years ago and it's still going strong, but you're right you wouldn't want it back if it was yours or even another one by the same company even
