15THE BASICS ELEMENTS OF A GOODDESIGN:• GOOD ENGINEERING is obviouslyessential.• FLAT DECKS. The flatter deck lines have anumber of advantages. Secure footingwhile on deck at any time in rough conditions,life lines are at a sensible protectiveheight instead of set down a level. A flatdeck is great for socializing, sunbathing oras a kids playground.• BUOYANCY. Buoyancy distribution is theplacement of buoyancy in the hulls. Ourdesigns have between 50 and“A power vessel that uses lessfuel and is capable of runningefficiently at higher speedssaves you money and time.”60 separate buoyancy tanks built intoevery shell so they are almost unsinkable.Most old designs hobbyhorse a lot makingthem uncomfortable and inefficient.Modern designs have the buoyancypushed towards the hull ends dampingdown the hobby-horsing tendencies andgiving a lot more safety downwind wherethe buoyant hulls stop nose-diving.Coupled with a lot of reserve buoyancyhigh up and forward in the hulls, thisadds an enormous amount of safety andgives you confidence off the wind.higher up is an ideal combination.• BRIDGEDECK CLEARANCE. HighBridgedeck Clearance is essential. A shortcabin length with long hull overhangs is agood safety feature. Good clearance on aplaning hull cat would be 600mm –800mm, or 1m—1.2m for a power catrunning displacement hulls. Chamfer panelsadd high reserve buoyancy and needless clearance than a similar cat withoutthem.• FUEL ECONOMY AND CRUISING RANGE.When discussing sailing designs we oftentalk about speed and performance as beinga real safety feature, and our powerdesigns are no different. Good power designsshould be capable of speed in allkinds of sea conditions safely, as severeweather can be outrun or avoided, andthere is no need to spend time waiting fora gap in the weather. Fuel economy isimportant for saving you money, andtime. Having a vessel that uses less fueland is capable of running efficiently athigher speeds means less time at sea,more time fishing or relaxing on thebeach and a smaller risk of bad weatherwhile on that ocean passage or weekendtrip. We feel a healthy fuel reserve isextremely important, and being able tocarry enough fuel to get you safely thereand back, and keep you going shouldsomething go wrong cannot be emphasizedenough.• A soft ‘V’d entry, quickly picking upreserve buoyancy with lots of reserve
