Bulge in Engine Hatch Cover and elsewhere.
I've separated this topic out from earlier emails (about delaminating washboards) as I may have a similar issue. I know Amel embedded metal plates with threaded holes in the hinge mounting plates of the fiberglass cockpit floor to received the bolts from the engine room hatch cover hinges.toggle quoted message Show quoted text
Is it possible they also embedded metal plates for your hatch opening pistons (I don't have those on my Santorin) and that they have corroded over time, expanded inside the fiberglass and are causing the bulging in the fiberglass floor? That would explain why Riza's fix didn't eliminate the bulge. (It also would suggest the bulging may continue - it's all very slow, of course.)
I ask because it looks like I may have a similar issue at the base of the aft-most port stanchion. For your engine hatch cover bulges, would it make sense to put some passivating chemical on it, like phosphoric acid, to stop further damage or as a preventive treatment for those who don't have damage appearing yet?

I will endeavour to go and see him this summer. What does surprise me is that this happens at all. The hatch is not often left open for long periods and when closed there should be little upward thrust. But happen it does.

Hi Joel Potter & Olivier Beaute,
Maybe one of you can chime in and explain to us how to properly rectify the problem with the bulge on the engine hatch cover. I also have the bulge and have been considering putting stainless steel plates on the inside as some others have done but I cannot see any compression or stress cracks on the inside where the struts are mounted. That makes me think there might be something else at play and not just the force from the struts pushing it through to the outside. Is there corrosive metal built into the hatch?
Your or anybody elses input would be much appreciated.
