A fun comparison: what you are seeing is the CIY-16 hull model nested inside the volume of the 18-footer. The 16 is comfortable with 2-3 so you can imagine the space in the 18, especially with the wrap around seating.

The building jig set up of the 18 uses particleboard (orange) for the strongback and molds. Bulkheads, frames, and centerboard mount as part of the set-up, as does the stem and transom. When the boat is flipped, only seating and tank tops need to be installed.

The new Calendar Islands 18 started with the hull model of the CIY-16, a group of loyal crowdfunders, and the involvement of a key collaborator, David Cockey. David, a former head engineer for GM, is also a traditional small craft aficionado and has helped me in several fruitful projects. Starting with my enlarged hull of the 16, he began sculpting the lines of the 18. Over two dozen versions later, we had what was a fair, beautiful hull model. “The guys”, as I call them, helped fund some of this design work and patiently awaited the first kits. Jeff McDonald, fellow Small Reach Regatta sailor and the original member of the “gang of four”, wrote the design brief and will be taking hull #1.

While David was finishing the lines of the hull, I was sketching the interior and sail plan. Once we had a finished hull model, I went to work developing the interior to be open, comfortable, and inviting. Don’t let that make you think this is a lazy man’s boat. With a nice run aft, she will certainly scoot with a following sea and provide some fun sailing. But with the comfortable seating inside and the easily reefed lug rigs, the boat will feel stable and comfortable when it breezes up. The wide, wrap around seating, will provide plenty of space for skipper and crew.

Construction is glued-lapstrake plywood (9mm Okoume) planking over frames and bulkheads also precut in the kit. The bottom and garboard are quasi-“stitch-and-glue” style - glassed over to create a solid, abrasion resistant surface for beaching. A complete epoxy kit provides all the adhesives and fiberglass to get the job done. The interior takes 6mm ply tanktops, 9mm ply seating, and cedar floorboards. Gunwales, outer stem, and interior trim are select hardwoods. A complete hardware kit provides all the fasteners, fittings and rigging needed.

CIY 18 Design Brief

  • A Safe, seaworthy, weatherly, capable, beach cruiser with classic lines

  • Dimensions: 18' loa x 6' beam w/ healthy amount of freeboard

  • Draft kept to a minimum to allow for beach-cruising and launching in shallows

  • Capacity for 4-5 adults in daysailer-mode or 2 adults/2 kids + gear in cruiser mode

  • Displacement is light: towable by a typical sedan w/ 1000 lb towing cap.

  • Appropriate hull weight to make it easy to launch and retrieve, in particular at shallow ramp

  • Fullness of hull fore/aft will contribute to goals of boat and create the underwater volume needed for capacity

  • Plywood-epoxy construction featuring bulletproof glassed bottom and garboard w/ glued-lapstrake topsides (6 planks)

  • Below sheer, airtight tanks in bow and stern to provide flotation and storage

  • Side benches with airtight tanks underneath for additional storage and flotation

  • Inside of boat is easy to clean and keep clean; no hidden or inaccessible spaces

  • Transom-hung, kick-up rudder w/ NACA foil shape and impact-releasable hold down

  • Auxiliary power is oars or a small OB mounted on transom

  • The boat can be rowed by two people. One sits on a thwart that braces the CB trunk; other sits on a removable thwart

  • CB w/ NACA shape and uses bungee cord hold-down system

  • Free-standing, lug-yawl rig of generous sail area set on hollow masts & spars

  • Boat is good to weather even in a chop and predictable/mild-mannered in a breeze

  • Easy enough to single-hand yet plenty to do for crew. Mizzen larger % of sail area than typical yawl, perhaps.

  • Classic lines complimented by 6-strake layout and more sheer than CIY16.

It took a village! Thanks to my supporters, we’ve launched a new boat....learn more about crowdfunding
