I am going to replace the handrails on my 1996 Hunter 37.5. Does anyone know how they are bedded/mounted to under the deck? Is it plywood, aluminum backing plates glassed into the underside of the deck? I assume the handrails are just screwed through the deck into a plywood core. The reason I ask if aluminum backing plates is that when I had a 1979 Hunter 30 and was replacing the traveler I discovered there were aluminum backing plates glassed in under the deck to recieve the mounting bolts. Not only was there aluminum, the glassed in aluminum backing plates were tapped for the bolts, making the reinstallation easier and more secure than I believed was going to be the case.
