I'm looking to replace the ports on my older sailboat. The plastic
plates are crazed, and the aluminum frames are flimsy. I'm
considering the Bomon company for custom ports, some fixed some
opening. Does anyone have any experience with Bomon's work? In
particular (as you might expect) I wonder about the watertightness
given their mechanical clamp design versus bolting in/through the
fiberglass.

Thanks,
Peter
