Calendar Islands Yawl 16 Update

Specs

LOA 15' 6"

Beam 5' 2"

Anticipated Hull weight 150-200 lbs

Displacement ~520 lbs

Here are some screen shots of the CIY model with lapstrake planking. The garboard is actually stitch-and-glued to the bottom, glassed, then the rest of the planks are plywood lapstrake with no fiberglass required. The bottom exterior is definitely oriented towards a lot of beaching as this is a sail-and-oar dinghy with an emphasis on sailing.

The waterline shows quite a bearing aft which should allow for a good planing when the wind is up and the crew is sitting aft and hiking out.

Now that the hull is complete, I can begin thinking about how to layout the interior structure with CNC cutting and kit building in mind but also so that the boat can be scratch built from just the plans or full size patterns.

I'll also sketch the rig but I bet folks know what the rig will be since its implied in the name. The CIY is named for the over 365 islands that dot Casco Bay. These islands and the sailing around them are the intended waters for this exciting boat.

The plan is to find a willing boat builder out there to build the first hull. I will sell the kit at my cost. Its a great way for someone to get into the boat they want for significantly less than what will be the retail cost.

New Boat: CIY 16

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!
