: I am in the process of making my Yost sea otter. My problem is with the

: 1, Make a traditional masik and fit it along with the form that is called for

Hi Scott,

I did sorta the same thing on the modified Sea Ranger I built this last fall. I had a keyhole skirt that wasn't being used so made the coaming to fit it, which was about half again longer than the one Tom called for on the plans. I just made a half frame spanning the upper frame rails to support the front of the cockpit coaming (on that boat not really a masik since your legs really would never contact it being quite far forward), but worked the same way. Better than moving the frame, you'd introduce a change in the hull doing that which means you're not building what was designed. A change in the deck doesn't change the hydrodynamics like a change in the hull would, safer that way.

If you need it, I can find pictures to help (I think).
