Re: Benataeu grid construction
Those are cracks in the gel-coat surface of the structural grid and will develop over time as the hull works. The more important issue is the integrity of the lamination between the grid and the outer hull which is intact.
Ah okay. I really wish it was easier to see exactly where the grid is joined to the hull.
The structural grid on the Firsts typically extends about 750 mm (≈30") above the bottom of the hull on either side and is bonded in place with an epoxy adhesive.
So you're saying that direct grid delamination occurs at a specific height? I think some of the surveyor markings appear much lower. Can delamination appear in such a way where the grid is still intact and joined to the hull? Or is any delamination a sign of a system wide failure and it doesn't mater where you find it?
