Hey folks. Need your help. Have an 06 CD 25. Boat 1100 miles away. ( I think it made it thru both earthquake & hurricane) Will visit shortly. Does anyone know the dia. of the S.S. gunwale rails. I am trying to mount a bimini and need a 2 piece slide jaw to mount to rail. This is the piece that holds the support tubing. I don't want to poke holes in fiberglass.
Thanks

That would be 1" stainless like the rest of the rails. Only the main vertical sections of the radar arch are larger on our boat at 1.25"
