Hello, on my 1988 PSC 34, I don't have a 1/4 berth behind the nav station. I have two equally large lazerettes instead. I was wondering how many boats are configured like this and has anyone had to access the aft water tank in a boat configured like mine. I have discovered that there are some small cracks that are seeping a small amount of water. I understand that the cover will somehow need to be removed. The problem is the backrest of the nav station is somewhat built on top of the water tank access panel and I don't think i will be abe to reach in far enough thru the inspection port.
