Firstly, all Ribs will develop stress cracks along the transom area indicated in your picture - and within days of first being used.
Why do people think like that, it lets manufactures get away with all sorts of sh*t.
Not all ribs crack, and if they do then they arn't built right.
Gell cracks are very different from structural faliures, and if the structure is sound then how does the air get through it?
Given the relative strengths of wood and grp, even a basic csm lay up, then if the glass is broken so is the wood.
Daniel, if anyone looks at your boat unfortunatly they will not know what the extent of the problem is without destructive investigation. Don't trust any one who says they can, best they can hope for is to make an educated guess, though if you get the right person then that guess can be fairly accurate.
If this is not a common problem with that model, which I susspect it is, then the build is wrong, give the builders hell.
