We are just about to buy a '91 37.5 (moving up from a 28.5), the survey is being done on Thursday, and the latches on the hatches on boat we are looking at are not 'tight' ... with the latches completely closed, there is still play in the hatch, and pushing the hatch up from the inside it opens very slightly. I know, therefore, that in any real sea, the water is going to come in by the gallon. Is there any way of tightening these latches? Thanks. (something tells me we're going to have a few more questions).
