New 12 to 15M Power Cat Catamaran Design


Calypso X1 with imboard DieselsCalypso X1 with Outboards

15.6 Meter Inboard Dive Boat Version             12.9 Meter Outboard Dive Boat Version


This design is based on the proven Calypso X1 design which been a great coastal dive boat. This high speed aluminium catamaran showed excellent performance. The original 13 Metre Power Cat was powered by twin mercury 350 H.P.  four stroke outboard engines giving a top speed of over 27 knots and a fully loaded speed of 25 knots with 28 divers. The aft’ deck has a fold down platform which can be used for both beach landing and as a snorkeling/dive platform at sea. The dive platform is attached to a fixed platform which extends out past the outboards. This is complemented by three fresh water shower units. Beside the platform is an aft’ full sized toilet compartment which is a nice change from the cramped set ups of similar vessels this size. The foredeck is passenger friendly with access through a water tight door. Click here to see Video


This spec’ boat can accommodate quad 250 H.P. Outboards for a top speed of 36 Knots+. The design can also accommodate twin 350 H.P outboards for a top speed of around 26-27 knots. Also the same design has been stretched out to 15.6 Metre in the past with inboard diesel engines (twin Volvo 330 IPS drives). The results were really good with no reduction in speed (27 Knots) and excellent maneuverability. The complete design and kit file was supplied and the build time is a very short 12 weeks.
