Core Sound 15

Designed by Graham Byrnes

A 15 ft 2 in cat ketch daysailer by Graham Byrnes of B&B Yacht Designs, released in late 2003 as the smallest of the Core Sound series. Stitch and glue plywood, 300 to 350 lb, 100 sq ft of sail on two free-standing masts, a draft of 7 in with the board up and space for up to five adults. B&B sells plans, digital plans and a made-to-order CNC kit, and has published a 21 part video series on building one.

The hull is wired flat and unfolded with B&B's butterfly method, so no strongback is required and a careful first-timer can manage it. Budget 350 to 600 hours as a rule of thumb, less with the kit. Real hours from logged builds are below.
