Passion Catamaran Stuart Ballantyne

A ‘Passion’ for Catamaran Design

Stuart Ballantyne has a passion for sea vessels, so much so that he named his 56 foot catamaran after it.  ‘Passion’ is an innovative twist on the traditional catamaran which was designed over 15 years ago by Stuart and is referred to as a Small Waterplane Area Twin Hull (SWATH) as opposed to a catamaran.

The vessel has many appealing features for those that appreciate the cruising style of a catamaran including:

  • A 7.4 metre beam with a draft of 1.0 metres.
  • Less pitching, greater hull efficiencies and better handling through its bulbous bow design.
  • A wide-open throttle comfortable for 23.5 knots or 44 km/hr.
  • Yanmar 6LPA-STP2 engines.
  • Modest fuel consumption of 22.5 litres per engine per hour and 1000 nautical mile cruise range (at cruise speed of 18 knots).
  • 4000 litres of fuel on board
  • Built on alloy and fiberglass.
  • Incorporation of motor and motor sailing configurations.

With its Gold Coast design through Stuart at Sea Transport Solutions and the quality build by Strategic Marine in Vietnam, ‘Passion’ is setting the precedent when it comes to enhancing and diversifying the capabilities of the build and structure of the traditional catamaran.

Yanmar Engines Offer the Perfect Fit

Stuart Ballantyne, designer of the SWATH catamaran ‘Passion’, was extremely specific in the capabilities of the chosen engines that would be used in the vessel and after a lot of research, decided on Yanmar.

Designed and manufactured in Japan, Yanmar Co. Ltd was founded over 105 years ago with their success in producing reliable and quality products such as heavy equipment, watercraft, diesel engines and unmanned aerial vehicles.

The Yanmar engines that were inserted into vessel were the 6LPA-STP2 and provided the required performance and preferred fuel consumption for the 17 metre catamaran that was designed on the Gold Coast at Sea Transport and made in Vietnam at Strategic Marine.

With the Yanmar engines ticking over at 2800rpm with the impressive fuel consumption of 22.5 litres per engine per hour at the comfortable cruise speed of 18 knots 22.5 litres, the engines can travel 23.5 knots with no compromise to performance.
