GRP Sheathed Marine Ply

[Cameron]

Does anyone know much/have an opinion about marine ply sheathed in GRP. Are you likely to get a solid, seaworthy boat made of this?

GRP over native wood seems to have been a common approach in my home country of NZ (I live in the UK at the moment).

Many thanks

If it was done from new there is a chance that it is ok but beware. Polyester is not a glue and doesn't bond well with ply,look at all the boats with ply bulkheads, they have a habit of becoming onstuck.
Tap all over for any voids as there is where the rot will start. and make sure that the bilges are fairly dry, as putting a waterproof membrane , of course turns it into a container.
So it can be ok, or a dog, do a lot of checking.
However the use of epoxy is ok .

There was a post dealing with this last year and a lot of useful advice was given. I rarely have any luck finding old posts but someone who is more expert may be able to find it for you!

The recent (ish) thread! Some good advice given (as always!).


Sheathed Ply - How to tell if (when?!) it IS covering problems??


Gave me a bit to think about - I decided not to proceed, but she was rough old gal!
