The CORAL SEA 35 CATAMARAN is designed specifically for the builder who wants the maximum boat for minimum cost and building time. To this end the vessel features separate hulls connected by solidly mounted cross beams, and a simple, easily built, trunkated 'V' hull shape. The trunkated 'V' is as simple to build as the straight 'V', but has better sailing characteristics, such as less wetted surface, better tacking etc.

The Coral Sea 35 is designed for safe, comfortable family cruising, with bunks for 4 in separate cabins, and room for 4 more on the dinette and settee in an emergency. It also has a large and functional toilet / shower area, room for a chart table, and a huge cockpit for socializing. There is excellent headroom with over 2 metres in the working hull areas, and good sitting headroom in the sitting / sleeping areas.

For simplicity and ease of construction the hulls consist of a plywood shell wrapped around a framework of plywood bulkheads and timber stringers. This is still the easiest way to construct a timber boat, and when combined with timber / epoxy construction, is a very cost effective way to build a sound vessel.

The rig is a simple but efficient; sloop, with a large sail area for light weather cruising, easily reefed in heavier winds. The rigid beams allow the vessel to carry an efficent rig which can stand up to the weather. The rigging is as simple as possible, and is based on the KISS principle.

Auxiliary power is from an outboard in a separate pod beneath the cockpit. The vessel features small stubb keels for cruising simplicity, and efficient transom hung rudders for positive helm control. Steering as designed is by tiller, however wheel steering can be installed as an alternative. The Coral Sea 35 is an easily constructed vessel capable of providing it's owners with years of comfortable and fun cruising, or ocean voyaging.

Since first launching, the CS35 has proven to be a safe and seaworthy vessel, sailing well in all conditions, and with a very good motion, displaying less 'hobby horsing' than one normally expects from the polynesian style of cat. She also points well for this type of boat, due to the mini keels and efficient rig. All round, she is a safe and seaworthy world cruising yacht for the budget minded.
