Sean,

Which Yost design is your craft please?

I am at about the same stage with my Sea Cruiser as the craft in your pic [except for the actual coaming].

Did you have the cockpit coaming made and available at the time you installed your deck beams? I am concerned at ending up with an unsightly bump/bulge in the skin (will be 9.8oz ballistic nylon + Corey's Goop) caused by the foredeck beams being proud of the frame at the fore end of the cockpit (Frame #3) and not "faired-in" with the coaming or coaming ring.
I think now that I should have continued my deckbeams aft of Frame #3 to meet the as-yet-not-built coaming and/or left the deckbeams unglued until the coaming was there to check the fit-up.

Sean, if you have a lengthy response with lots of pics then please email me at mcbunny09@gmail.com
