Laced the mizzen luff to the custom mast with 1/8th inch nylon line from New England Ropes, used a marlin hitch. The mizzen is loose footed, boom will be secured to the stern and act as a boomkin, sheet will run from clew, through a block on the boomkin and forward to a fairlead jam cleat on the mizzen thwart.
Mizzen can be rolled up to furl, or if the boomkin is released the whole rig can be wrapped up like a burrito and stowed in the bilge.

Grumman 17 SCOUT 02 Jul 19 Mizzen Rigging
02 Jul 19:
Drilled a bee hole in the top of the mast to attach the head of the mizzen. Used interlocking bolts from Sunfish spars to bonnect the boomkin to the mast, that will keep it steady at the tack of the sail, and we tied the middle of the boomkin to the ster of the canoe, so the mizzen is boomless like the Darscombe Lugger mizzen.
We could have figured centers of efforts for both sails, square footage, centers of lateral resistance, lots of math and come up with a technical answers as to where to put a leeboard....
...instead, I hauled SCOUT out to the bay, tightened the sheets, set the breeze on her beam and moved my finger along the gunwale til I found the balance point. We'll put the leeboard just forward of that so that she'll weathervane when I fall overboard.
