EVA MAY - the best of both worlds

EVa-May a Princess 41, was built in 1979 and purchased by Hush Craft in July of this year. Discovered lying ashore in Windsor by Managing Director Ben Simpson, he thought EVa-May would be the perfect vehicle to demonstrate our full hybrid solution Thrust Pilot® (patent pending) pod.

Designed around a boat’s typical usage, the solution allows normal operation of the vessel offshore at high speed.  It can then seamlessly transfer to and from electrical propulsion when the vessel reaches estuaries, rivers or lakes with speed restrictions, reducing: fuel costs dramatically, noise pollution by 100% and increasing engine life.  Find out more about the Thrust Pilot solution here.  After a three week delay due to Coots nesting on the swim platform she was transferred by road to our boat yard in Brightlingsea where work on her transformation has begun.

EVa May is structurally sound and has been for 36 years so reusing her old engine, and installing our Thrust Pod should make her environmentally suitable for another 36 years.  Works so far have included new head lining, lower energy lighting, new heating system and bonded windows as well as ongoing epoxy treatment to the hull to prevent osmosis.

Along with the installation of the Thrust Pilot, Hush Craft will project manage her re-fit, upgrading the overall style of the vessel to fall into line with modern times.

The company covers all aspects of installation and more importantly the compatibility.

Hush Craft experience and technology provide leisure and commercial boat owners with quiet, green cruising and excellent maneuverability, whilst preserving the main propulsion systems from long-term idling and inefficient speeds.

Benefits can include:

  • 100% redundancy of propulsion and steerage
  • Silent, efficient cruising
  • Zero emissions whilst under electric propulsion
  • Directional thrust for improved maneuverability
  • Prolonged service requirements on main engines
  • Reduced sooting-up on main engines
  • Fuel savings
  • Additional domestic battery life if required
  • Access to zero emission cruising areas
  • Sea trials with EVa Mays original engine form will begin in September to determine her top speed and fuel consumption. True performance data in the current state prior to the installation of the hybrid system is crucial to the development of future systems and vital information for the supply of correct propulsion solutions.

With charging points along the Thames on the increase we aim to take EVa May from Limestone to Oxford solely under electric propulsion from the 17th of October.  A list of marina visits will be posted below shortly.

We invite you to be the first to experience the technology by enquiring about our test cruises here.

This page will show regular updates as and when they happen.

What's happening when

July 2016 - New head lining, installation of lower energy lighting, engine service overhaul, replacement of domestic and starting batteries, new heating system


August 2016 – New bow thruster, new heads, replacement wiring, new windless, overhaul of plumbing system and installation of black water tanks, full entertainments package, new navigational instruments


September 2016 – Sea trials carried out under original form.  An average maximum speed of 18 knots was achieved over a measured mile with 80% fuel tanks and 50% water on board.


November 2016 - External Thrust Pilot ready for installation.  On vessels with existing swim platforms the Thrust Pilot would be integrated.


December 2016 – Vessel out of the water for fitting the external Thrust Pilot.

EVa May begins her journey with Hushcraft.

Windsor, 4th August 2016, Hush Craft today began the project to convert EVa May to a full hybrid solution, by transporting her by road to our yard in Essex. (more…)
