I searched teh archives and couldn't come up with much on this topic. On my Hunter 356 boththe forward and midship overhead hatches just refuse to stay open by them selves. I spoke with Lewmar and they said to use an allen wrench and simply tighten the allen screw. Ok. Did that and teh mid ship is better, forward still no good. Is their another trick? Has anyone done the retrofit stays for the hatches? How difficult to install and is it worth it? While I'm asking, opening port in the head also doesn't want to stay in the open position. I don't see any way of getting to that allen nut without disassembling the entire port hatch.
