In Response To: Skin-on-Frame: coaming/aft beam gap in SOF kayak (Robert Evans)

: I am building a Greenland SOF kayak from Mark Starr's book. I've made some
: mistakes, but I am convinced that, at worst, it's going to float!

: My question is, the aft deck beam (isserfik) has ended up about 2cm below the
: deck as defined by the apummaqs, as are the other deck beams. The photos
: in the book look the same (figs 1.9, fig 4.8). However, some of the
: drawings make it look as if the beam should be flush with the deck (figs
: 1.2, 5.14).

: My question is, if the deck fabric is going to run under the cockpit coaming,
: either the coaming is going to "float" above the aft beam, or if
: I lash the coaming down, there will be a substantial depression between
: the bottom of the coaming and the rest of the deck as defined by the aft
: stringers and apummaqs.

: Should I attach a shim under the coaming? that would also let the forward end
: of the deck stringers run right up and level with the bottom of the
: coaming.

Hi Robert,
I wouldn't worry about the coaming floating above the deck beam (isserfik), in fact some builders deliberately do this to make it easier to do a lay-back roll.
If you want a connection between the coaming and the isserfik, you could extend the aft deck stringers forward enough to support the coaming, if you haven't skinned the kayak yet.

Hope this helps,
