The Coral Cove 40 is intended to fit somewhere between the polynesian catamaran concept and the more high tech. catamarans. The Coral cats use absolutely no exotic materials. To keep construction simple and costs low they are designed for all plywood construction, using the proven timber / epoxy construction technique. The Coral cats all feature separate hulls connected by crossbeams. Beams are solidly mounted. Cats can be built as seperate hulls to 80% completion, then transported to the water for final assembly.

The Coral Cove 40 has a multi-chine hull with mini keels and transom hung rudders for cruising simplicity. The design has several accomodation options for versatility and owner customisation. The cockpit area features a solid floor fitted between the pod inner sides and the two main beams.

Auxiliary power is provided by twin outboard motors mounted below the hull pods.


The CC40 rig is a masthead sloop. This is a simple, low cost, proven cruising rig.


The CC40, like all of the Coral Cats, features a fiberglass sheathed plywood hull shell over a framework of plywood bulkheads and timber longitudinals. This has proven over time and thousands of boats, to be the quickest, cheapest and best alternative for amateur builders on a budget. Absolutely no exotic or expensive materials, such as expensive foams, balsa or carbon fibre, are be used in the construction


The accomodation in the basic layout is intended for long term cruising, and features a double berth forward in each hull. Both hulls have a raised seating area in the mid section, made larger and more spacious by extending into the hull pods. To starboard the area is arranged as a dinette with a pilot berth inboard, whilst to port this area is a large and comfortable lounging area.

Aft to starboard is the huge galley and a single berth (which may be eliminated in favour of an even larger galley and extra lazarette), whilst to port the aft area is given over to a large W.C. area with seperate shower compartment.

As options for long distance cruising, the port hull center area may be arranged as a seperate owner's cabin, with a full size double berth extending into the pod area. Forward of this can be either a huge storage / workshop area or a seperate single cabin.
