Our friend Alan dropped by to offload a lateen sail rig, leeboards and rudder for the Grumman canoe (jiman) SCOUT. He also brought some nice wooden booms and a Super Sailfish sail. Skipper already scratched her initials on all the parts.

Alcort Alcove
02 Apr 22:
Since the wooden Alcort hulls had a new home, we decided to reunite them with their rudders and daggerboards.
1953 Alcort Sailfish 12 WINNIE. Later called the Standard Sailfish. The daggerboard on the far left, bottom, is her original 31 inch daggerboard. We upgraded her to a 39 inch board from a 1965 fiberglass Sunfish, and she tracks and tacks better as a result.
1953 wooden Alcort Sunfish ZIP. Her upgraded daggerboard is from the 1980s, a larger and longer "Barrington" board developed by the Barrington Frostbiters, and she sails better with a 1960s era spoon tip rudder. Also in the photo are the rudder and leeboards for our 1960s Grumman 17 SCOUT.

Since we cleaned off some wall space in LEWIS BOAT WORKS, we hung up the Christmas yard art.
Current state of the tool trollies.
It's April!

Grumman 17 SCOUT 04 Jul 19 Lines and Leeboards
04 Jul 19:
Took SCOUT out this morning with just the gaff main and a kayak paddle, winds 4-6 mph. Paddled upwind for about 20 minutes then raised the gaff. Turned and ran downwind, sat midships and steered with the paddle, gybed and even got through a tack with the help of the paddle. We could hold a beam reach without losing too much ground.
Rigged the mizzen.
Canoe with a boomkin!
Mizzen sheet jam cleat with a fairlead.
We went with the free footed mizzen and boomkin so we can furl the mizzen easily.
Skipper's leeboard design, repurposed Sunfish rudder and gudgeon. She'll be able to control it from the stern seat.
Clark's leeboard design, variant of a Sunfish daggerboard. We'll try them out one at a time and see which one we like.

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.
