I am looking to install folding seats on my palm beach white cap 151. There is a built in fiberglass bench/ledge behind the center console. Right now I am using cushions but want to upgrade to folding seats, possibly a bench seat. Looking for advice or suggestions on how to mount with little to no riser and if anyone has had success installing on this type of boat. Did you use any thing between the mount and the hull or on the underside?
