Tests are under way to determine if Solar Navigator should be fitted with auxiliary generators. Fellow AYRS member, Peter Worsley has built a number of catamarans with rotary sails, which have the extraordinary ability to head straight into the wind.
While it may not be possible to generate sufficient electrical energy to overcome headwinds, nevertheless, there is some advantage to using wind energy to supply the onboard electrical needs of the vessel and crew.
Testing catamaran auxiliary generators in side wind
If Solar Navigator is equipped as per the picture above, with wind turbines, she would be a true hybrid craft. Whichever way you look at her, we hope you will agree she is something to look at.
The model above is not yet equipped with the Sun Tracker system to ensure correct alignment of her solar panels. Nor, the aluminium spaceframe, which it is hoped will reduce weight and possibly reduce drag.
It is hoped the combined technology will allow us to set model speed and endurance records (beat our own records) in the near future as part of our development of the full size vessel.

In 1995 it was proposed by our designer that a solar powered boat would be able to circumnavigate the globe using only energy from nature. He displayed the first of his development models at the Earls Court boat show in London into 1996.
With a boat the most important component on the agenda is the hull. Solar powered boats provide marine architects with new challenges. There are as yet no conventions. Nobody knows what will work best, because so little has been put to the test. We can attest to that because we've tried 5 hull designs to date, improving on each one. Two SWATH designs (one above), two catamarans and a trimaran. The 6th design is not strictly speaking a trimaran, it does though have three hulls; so we're billing it as a trimaran. A hull design like this has not been built to date, to overcome the ever present drag and wave drag dilemma.
The other major challenge is panel design. How do you increase panel area and get as much of it facing the sun when the sun moves relative to the route, and of course keep the boat stable in all seas. We wanted at least 2 kilowatts per ton of vessel mass and can comfortably achieve that.
Not to detract from the incredible achievements of the PlanetSolar team, but the SolarNavigator project aims to improve on the record 0f 585 days set in May 2012 with our brand new design. Our advantage is that we have more than twice the power to weight ratio of the current record holder with a lower drag hull. This needs to be verified before we can go to the construction stage.
This project represents a unique opportunity for any global company with eco friendly ambitions. If this is of interest to you please let Blueplanet Productions know using the contact details below.

On the 4th of May 2012 the theory was proven to be correct by Raphael Domjan and his superb boat the Turanor Planetsolar, thanks to generous sponsorship by Candido Swiss watches and Immosolar, leaders in the field of solar energy management.
Now the benchmark has been set, it will undoubtedly inspire others. As with so many things once a pioneer has shown the way, inevitably, the record stands like mountain to be scaled.
WE WILL PUBLISH DETAILS OF THE LATEST MODEL BUILD SHORTLY
The latest Solarnavigator is a battery electric trimaran with an extremely efficient active hull that runs on solar power. The model shown here is just 150mm long. The radio controlled test model is 2.1 meters in length.
