The Calendar Islands Yawl 16
A Sail-and-Oar Dinghy for one or two people
The CIY 16 began as a 19 x 6 1/2-foot daysailer design with a deck and coaming with a bit of Herreshoff flavor. A friend who sails the Goat Island Skiff design by Michael Storer wanted a similar boat -- singlehanding, lightweight, lug rigged sail-and-oar dinghy -- but with a hull shape more amenable to Maine waters. I immediately thought of my CIY lines that I had drawn years ago and that had been sitting untouched and in need of inspiration. I had already put the lines into the computer so I scaled them down and reworked them to make this hull. The specs are:
LOA 15 1/2'
Beam 5' 1"
Displacement ~522lbs
Depth amidships 1'9"
DWL is 3'10" x 13'2"
Cp is 0.54
The hull has a wide plank keel for rolling the boat up and down the beach. The skeg is there for tracking under oars, but the cutaway allows the stern to come through the wind when tacking. The lines are fairly straight forward and full aft. In a breeze she will plane. Yet trimmed on her DWL, the transom is out of the water and the stem is in the water and she'll row fine with 10' oars so long as we keep her light. Construction will be 1/4" plywood: bottom and garboard stitch and glue style, with lapstrake sides, about 5 strakes total for topsides.
It's always fun designing something really new. The next steps are to put in all the planks in the model so look forward to that post. I'll be looking for someone to prototype the boat. Let me know if you are interested. Stay tuned!
