Explorer yachts provide the truest essence of yachting's purpose, as they are specifically designed to throw off the bowlines, explore the great blue beyond and connect their owners to the water.
This is an exceptional opportunity to purchase a custom built motoryacht completed by one of New Zealand's leading builders. Mana Moana has been built from the hull of a sleek Swedish Navy Patrol Boat into a stylish expedition style explorer with the combination of functionality and modern fit-out.
The hull conversion commenced in 2014 with design by renowned New Zealand naval architect Kevin Dibley. Also involved are Interior Designers including Kit Carlier and New Zealand Structural Engineers working together to create this beautifully appointed motoryacht.
The vessel can be sailed by the owner or with crew if assistance is required and separate crew accommodation is provided. The main accommodation includes three double cabins with ensuites plus a single cabin.
The build incorporates the latest strength and safety regulations plus surveyed to comply with the rigorous requirements of the Australian commercial vessel rules, NSCV 2B. The compliance survey has been carried out by the experienced Naval Architects and Surveyors, Sea Spark Limited. This special custom build incorporates all the aesthetics, ergonomics and efficiency expected in today's latest designs.
The vessel is currently over 50% complete with the custom fit-out remaining.
With New Zealand winning the America's Cup we expect heightened interest in quality craft such as this readily positioned in the South Pacific Region. It also reflects the example of what can be achieved with a combination of the best workmanship and efficient control of capital expenditure.

Design Brief:
Mana Moana has a modern low semi-displacement hull form to create a sea-kindly and fuel efficient performance. The design brief was for a vessel that has a sleek low profile, with a very stable and highly efficient hull form. A go anywhere, anytime motoryacht that a couple could use with family and friends. The interior allows for good entertainment with larger groups, but is comfortable and private for family, guests and/or charter.

Propulsion is provided by twin 740 HP MTU engines for a reliable and low maintenance operation with a long-distance cruise speed of nominally 10 knots and a top speed exceeding 20 knots

The hull is constructed from Grade A steel plate with frames and stringers and the superstructure is balsa cored fibreglass for strong and lightweight performance.
The low semi-displacement hull form provides efficiency and low power consumption. To achieve this a low VCG (vertical centre of gravity) has been implemented to maintain the safety at sea aspect of the design.

Additionally, all tankage is low in the bilges and keel of the hull. Another beneficial aspect of the design is for all the major weights, such as the engine room and tankage, to be located close to the LCB (longitudinal centre of buoyancy) to reduce pitching in a seaway. This assists maintaining constant trim between Full and Lightship loads.

Mana Moana is designed and built to the rigid Australian NSCV LR SSC-2B survey requirements.
