I recently purchased a Hunter 27' . The deck grab rails are in poor shape. I wouldlike to take them off, but unsure how. I think they look as if they are some how bolted through the deck and plugs are put in the channels for the bolts drilled right through the fixtures. I have no idea what to do; whether to drill these plugs out and install new rails or take my inside room of the cabin apart...or what? I don't see any screws at all in the cabin roof....does it have any? Anyway, how the heck do I go about this project....new rails are only about 50 bucks each...Second question: I noticed on a later version of my boat a beautiful front hatch cover made out of plexiglass or something suchlike. Can you buy these for my year of Hunter? The one I have needs work or to be taken out to the garbage.Truly, WayneC
