20m Tri Deck Wavepiercer Catamaran - Polaris
(See the build photos at end of page)

Designed for an Australian client, this 20m tri-deck wavepiercer was originally intended to fulfil the role of a Queensland coastal cruiser, capable of supporting the owner, his wife and their extended family and friends for extended periods. Unfortunately the initial boat was completely destroyed by a fire at the build yard, Q-West, shortly before completion in May 2004. Subsequently the boat has been rebuilt and was launched in December 2005. 

The comprehensive design package is now available to interested parties at a very competetive price and includes:

  • Detailed structures and systems drawings that have already received full plan approval under the Australian Uniform Shipping Laws Code
  • A full set of CNC cut files developed and nested for the entire aluminium shell and all internal structural components 
  • Detailed build notes that were generated during the initial build. 
The original interior, which could easily be altered to suit individual requirements, occupies two levels. The lower level incorporates a large cockpit suitable for game-fishing, a large open plan saloon and galley around midships and offers four cabins forward. These comprise of a master stateroom with extensive bureau / office space, walk in wardrobes and separate head and shower compartments, two double guest cabins each with en-suite, and a twin share bunk room. The mid level is dedicated to an outdoor area, large saloon and entertainment area and an enclosed portuguese bridge with access to the foredeck and side decks. The upper level is an extensive open outdoor area with partial shade cover from a hard top supporting the navigation and communications equipment.

This boat also boasts an elevator platform similar to that of one of her predecessors, the 24m 'Spirit'.  The platform will carry the tender at wing deck level over 1m above the static waterline, but will hydraulically lower to allow effortless launching and retrieval.  The adjustable height of the platform also makes it ideal for bottom fishing as well as a perfect way for swimmers and divers to enter and exit the water.  On Spirit, the platform has been used for activities as diverse as a golf driving and a skeet shooting range through to romantic dinners with the water lapping at the diner's feet.

The vessel  is powered by twin 800hp Caterpillar diesels offering a sprint speed approaching 30 knots, yet a range in excess of 2000 miles is easily possible at a passage making speed of 12 knots. Other powering options are available for increased speed or range.
