: Thanks for the input. Please let me clarify what dimension I’m referring to.
: I call I the lip width. Again, I’ve used 3/4 inch in the past but I’m
: thinking that by going to 1/2-inch the coaming lip would be stronger and
: less subject to being damaged.

My coamings are usually 1' from the deck to the top surface of the coaming. The lip is 1'4" thick
So this leaves a space under the lip of 3/4". The vertical surface of my coaming from the deck up
is 1/4" thick and the lip extends 5/8" out from that. So looking down at the top surface of my coamings
the surface is 7/8" wide.
