12m Displacement Power Cat

12m Displacement Power Cat

12m Alloy displacement hull

There have been several variations of this design built in NZ by Alloy Cats.

This is a well proven displacement hull cat with a good turn of speed and very good fuel efficiency.

Optimum engine size is around 160 hp for a top speed of around 23 knots. A couple of iterations have used larger engines of 270 hp with a small gain in top speed and no real difference in economy. The larger engines are more difficult to access for servicing in the narrow displacement hulls as well. Some clients prefer to have more than enough power, it’s their choice.

There are several variations available to the original design, wider deck house, longer wing deck, longer deck house, composite top, alloy top, variations in the interior and cockpit layouts, commercial charter use, and private yachts.

One of the great advantages in building in alloy with a ‘base’ design is that these variations are not difficult to undertake as each boat is CNC cut and the design can be easily customised to suit individual client’s requirements, production boat building without the cost of moulds.
