FYI, the standard FP
hull warranty is 5 years and is not automatically transferrable to the new Owner. The 5 years is, I believe, an EU statutory warranty so you'll find that
Lagoon, FP,
Beneteau etc. are all very similar.
On our
boat, we negotiated with FP to have the warranty transferred to us as second owners. FP have further offered a 3 year warranty on the
osmosis repair works (so a total of 8 years!). So, no worries there.
FP have issued a very detailed specification for
repairs which in essence is a peel, and
layup of two layers of glass mat with
epoxy resin. It'll be stronger than the original
hull so the hassle is probably worth it. It will, however add some weight to the
boat but probably not too much when you account for the
removal of the gel coat.
Hope that helps.
