SPIRITED 400 'Power'

LENGTH 12m  |  BEAM 6.5m  |  BERTHS 3 Doubles |  USEAGE Blue-water  |  KIT OPTIONS DuFlex Balsa/Foam, Plain Foam  


The Spirited 400 'Power' is a semi-displacement power cat with sleek lines and light weight structure. For those who like 'turn-key' cruising this highly efficient design is always in readiness for a quick getaway. The slim hulls run easily through the water and provide a very comfortable ride even in rough conditions. This design can accommodate most luxury appointments for an apartment-like finish and experience. 

The semi-displacement concept delivers a power cat that is fuel efficient enough for long range cruising. The hassle-free approach of a power boat means that you can enjoy a quick passage navigating a direct course. This design provides a very comfortable platform whether underway or at rest. As with any boat it can be as simple or as complicated as you wish; the end result is in your hands as the builder. The open spacious layout allows for ample living quarters for the crew whether living aboard or weekend cruising.

Cockpit The acess into the cockpit is via the aft hull steps with the bottom step being extra long and in effect acting as a duckboard ideal for entering/exiting the water when swimming, diving or unloading the tender. The cockpit is open plan with a wide curved seat aft and additional seating either side. The open plans layout offers the option of a clear area or space to set up a table and chairs when required.

Bridgedeck Internally this design has the galley to Starboard against the aft bulkhead; opposite this is a generous sized seating area. The bridgedeck cabin is high volume and accommodates a dedicated steering console area with comfortable seat and dashboard design. This space works cohesively between all areas and provides a hub for the living areas while underway or at rest.

Cabins Entering the hulls there are three private double cabins, the two forward are queen sized and have the option of an ensuite or a walk-in-robe leading forward. All areas are spacious enough for comfortable use with all berths allowing for generous sitting headroom. Head and shower amenities are situated aft in the Port hull with a dedicated engine bay behind the separate shower; the Starboard engine is located below the aft double berth.

Power The engine size is flexible due to the semi-displacement hull design which is efficient at any speed range. The recommended engine size begins at 50hp through to a maximum of 125hp in a shaft-drive installation.

On Deck The surfaces are flat and level for safe clutter-free footing from the cockpit moving forward to the foredeck. The foredeck flows seamlessly onto the trampolines and also level with the forebeam. Access to the flybridge is from the cockpit on the Starboard side. The flybridge is the perfect outdoor social setting with excellent 'birds-eye' vision of the horizon. An optional second top steering station can be fitted for full control whist enjoying this area and is also advantageous when docking from this position. 

Performance Expected speeds depend on engine size but cruise speeds will be effortless in the mid teens even with the smaller engines. Top speeds are in the high twenties with the large engines and in the high teens with the smaller sized engines. Given the fine entry hull design this design will cut through the water and offer a comfortable level ride in most conditions.
