The most important issue in the whole design, build, test process.

Special attention in this area is required for offshore catamarans, as they are unballasted craft and rely on quite differing parameters than other types of hullform to ensure safety, comfort and peace of mind to the coastal or ocean sailer.
The level of safety inherent to specific catamaran design is directly related to the architect, and those with personal extensive coastal and offshore experience are obviously going to draw a safer boat.

The process begins at the drawing board/study print stage and carrys on right through construction and seatrial time.
Important issues are:
Hullform with good resistance to fore and aft pitching,
Overall structural strength and rigidity with minimal diagonal twist and panel flexing,
Generous bridgedeck to sea clearances without protruding appendages such as external stiffening stakes, berth bulges, footwell pods etc.
A high, smooth bridgedeck surface offers least drag and a quieter interior,
Generous forward trampoline area, using open net (not taped forms) to allow easy passing of wind and water,
Light, strong mast and rigging with no running stays,
Cockpits with no dangerous sharp appendages and efficient draining back to the sea,
Good motoring power (2) instantly available, preferably diesel with long range ability,
Sails that can be hoisted, reefed and generally controlled from the safety of the cockpit,
Efficient pulpits, lifelines, sternrails etc,
Dry, comfortable interior with galley shower/toilet areas useable in heavy weather.
The best avenue for prospective persons to check and receive authenticity on safety records of the designers work is to contact present owners of his catamarans that have offshore experience and discuss directly with them.
