The little 9ft Oppikat has been built in nearly 20 countries around the world as one-off projects. Although intended for junior sailors to sail single- or double-handed, builders have reported that dad loves to sail the boat also, either by himself or with one of the juniors. I have been asked many times by potential builders if we have a similar but bigger cat that they can build for themselves. Until now the answer was no. But now we do have what they were looking for, we have the Bigakat 12. The Bigakat 12 is primarily intended for wood construction by amateurs, requiring moderate woodworking skills. Bulkheads, transoms, decks and the upper panels of the hull sides are all easily made from 4mm plywood. The lower sides and bottoms of the hulls are skinned with 6mm strip cedar and sheathed with a light layer of glass cloth in epoxy resin. Each hull is built over 4 permanent bulkheads and 5 temporary ones, which are set up upside-down on a board that can be mounted on a large table, workbench or sawhorses.Once skinned and glassed, the hull is removed from the board, the temporary bulkheads removed from inside the hull. Thosee temporary bulkheads are then set up on the board again with new permanent bulkheads to build the second hull. After waterproofing the insides with two coats of epoxy, the decks are fitted. |
The overall image is modern, in the style of racing cats. The keels, constructed onto the bottoms of the hulls, give windward ability and a pivot point for tacking, without the complication of daggerboards. Their draft of 10.5" allows easy beaching and sailing in shallow water. The rudders have foil-shaped fixed blades for simplicity. They do not project below the keels so they have protection in shallow water to reduce the number of concerns for novice sailors. |
