Plans for this catboat can be found in the book "Build the instant catboat" by Harlod Payson. Full size plans for the Phil Bolger designed "Bobcat" catboat are also available from the author.

It is a gaff rigged catboat 12'3" overall in length with 6' beam. It has a wide traditional catboat shape, with a single mast way up forward, but with a flat deck rather than a cabin. The construction method, called tack and tape in the book, is similar to stich and glue plywood and epoxy boat building methods where fiberglass tape and epoxy fillets form the seams. To cut out the full length parts from standard eight foot lengths of plywood I used scarph joints to create sixteen foot panels rather than use but blocks to join the parts as plans and instructions in the book show. I elected to make my own spars and and as many of the parts as practical and even sewed my own sail from a Sailrite ® kit.

As an overview here are some of the steps involved in the project. After cutting out parts for the frames, bottom, side and bilge panels I stopped to make spars and the sail then setup to build the hull. The sides were attached to frames B and E then pulled together at the stem and transom while adding the rest of the frames. The stem was laminated from five layers of plywood and the transom framed with douglas fir. The bottom and bilge panels were sprung on making it a double chine hull. Then the seams were filled with thickened epoxy and taped with fiberglass outside and inside. The outside of the hull was also sheathed with fiberglass cloth set in epoxy. The centerboard and rudder, rudder hardware and centerboard case were done next. Douglas fir was also used for outwales at the sheer where the deck will attach to the sides. All the things that must be done before putting on the deck were next including painting the interior. The deck and deck hardware, like mast partner halyard blocks and cleats mooring cleat and traveler, are next. Followed by more painting and finish work on the exterior then finally the rigging.
