I use 4 mm marine plywood and do not glass the coaming lip. I'm sure it will be fine without.

: To all more knowledgeable than I (which is everyone on here): In building a
: Chris Cunningham Greenland Kayak Hybrid with my friend Don Harper, I am
: finished with the coaming and rim. The deck and coaming riser built with
: strips (like in Nick's book) have been glassed and a fillet was placed at
: the base of the coaming riser on the outside of the riser before glassing.
: I glassed up the outside of the riser and cut off the excess glass. I then
: proceeded to build the "lip" by laminating on some 1/8" x
: 3/8" of Ash that was cut flat sawn into strips. Bending it around the
: front was not easy, so we went with the instructions in Nick's book on
: cutting it off flush with the front and laminating on extra strips. That
: went ok and now I am to the point where I have to glass the lip and inside
: of the coaming. My question is: will it be strong enough if I just glass
: up the inside of the coaming rim and over the lip but not down around the
: underside, and just add a fillet on the underside with 2 coats of epoxy on
: the fillet, but with no glass on the underside of the lip. By the way, I
: also laminated the ash lip strips together with West System G/glex epoxy,
: the strongest and most resilient epoxy made today.

: Thanks in advance for the replys.
