During electrical installations (winch)  I removed the plastic container where the batteries sits. You then get access to the spaces and joining between the inner hull and hull.  I noticed there were severe cracks in the glue at two/three places. As shown in the pictures, the cracks appears only one the port side (under where you will have your feet sitting in the coach) but the other joinings seems ok (last picture).

Has someone experienced this, or even had a look? Will it have structural impacts to the hull strength etc or is it glued for having a stable floor? How can this be fixed?

I have not removed my battery compartment. I can see some of the area when I remove the lower panel under the chart table, but there are no cracks.

The cracks are result of a grounding. It has to be repaired, and the work will be done by specialists. They will cut access through the innerliner and fixed by applying fiberglass/resin to build strong joinings.

Hello
IMO this is not a structural problem. If the inner hull will be part of the strength of the boat the factory will use GRP lamination to fix both hulls together and not(so far I can see on the pict) some filler or glue. I think
it is just to fill up te space between the 2 hulls so the floor can not go up and down.

Or, it could be much easier to glue to two large parts together during manufacturing. I don't think it is possible to fix them together in other ways since the innerliner is "fully covered" without other through access other to than very small inspection holes.
