Without pioneers technology would stand still. We'd not have air travel for sure, if not for a brave few pushing forward the frontiers amid a hail of skeptics. Pioneers such as the Wright Brothers 1903, Bleriot 1909 and Lindbergh 1927 (Atlantic) confounded the world, with Charles Kingford Smith 1928, crossing the Pacific and Amy Johnson setting a solo record from London to Darwin in May 1930, as Kingsford completed his world circumnavigation in June 1930.

 

Naysayers firmly in mind, the Cleaner Ocean Foundation consider it may be useful to anyone curious as to just how rapid a Transatlantic transit might be using only energy from nature, to plan a potential route (or two) for the Elizabeth Swan, such that if deemed a sporting challenge and the opportunity presents to dispel negativism as to the potential for future marine transport, that we have plans in place to demonstrate the technology in action - and a consortium of able experts to put such thoughts into action. We are thus forming an able group and actively seeking development and funding partners internationally.

 

If we can set a new solar powered water speed record across the Atlantic, while adding to our knowledge of wind powered hybrids working in concert with photovoltaic panels - to add a little sparkle - to the engineering challenge. Wind is of course solar power, created as energy from the sun is dissipated by convention currents from the equator to the poles. So long as it is converted to electricity for autonomous energy harvesting, that constitutes solar power.

 

But before this stage should be contemplated, a Channel crossing is a good idea to gain a bit of hands-on experience.

 

 

 

 

Very different designs, Catamaran Vs Trimaran frontal area comparison, with the Swiss boat having more to push through the air. The PlanetSolar also has increased wave drag from the central 'V' hull in rough seas. The Swann seeks to avoid as much wave drag as possible by raising the cabin and deck areas higher. The Swann is a longer boat, making it potentially the largest solar boat ever built as @ 5 Oct 2020. PlanetSolar has no wind turbine to capture additional solar energy, a missed opportunity, but then that is why R&D hails innovation.

 

 

TRANSATLANTIC RECORD APRIL 25 - 18 MAY 2013

 

The current solar Atlantic record is held by MS Tûranor PlanetSolar, a catamaran that left from Las Palmas, Gran Canaria, Spain, on April 25, 2013, and sailed across the Atlantic Ocean, traveling at a speed of 5.3 knots before it reached Marigot, St Martin, in the French West Indies on May 18, 2013. Despite several consecutive days of cloudiness the boat reached its destination in 22 days, 12 hours and 32 minutes - four days shorter than 2010.  The PlanetSolar previously held this record with a time of 26 days 19 hr 10 min.


Switzerland’s MS Tûranor PlanetSolar, is currently the world’s largest solar boat. Having departed Las Palmas, Spain, on April 25, 2013, the solar powered boat sailed 2,867miles (5,310 kilometers) across the Atlantic Ocean. It is difficult to compare the two crossings because they were conducted at very different times of the year. But it is sure that major maintenance over the previous winter - particularly to the propulsion system - had improved the ship’s performance, according to Gérard d’Aboville, Captain of the MS Tûranor PlanetSolar.

The boat’s energy consumption had to be carefully managed in order to maintain an efficient speed and reach St. Martin in less than 26 days. During the transatlantic crossing, the crew encountered phases of substantial cloudiness for several consecutive days and had to adjust the route. The adjustments increased the travelling distance by 7%, but enabled the PlanetSolar crew to avoid winds and unfavorable swells. Hence, route planning was as important for the Swiss boat as for the Elizabeth Swann.

 

The Clean Queen of the Seas, Elizabeth Swann

 

CAD DIAGRAM: The Elizabeth Swann is shown here with a wave piercing hull. She is of trimaran configuration with active outrigger hulls (or sponsons) that allow the vessel to trim for very efficient running. She has solar wings that fold for storms and track the sun, and a wind turbine on a mast, that can be raised and lowered and furled in high winds. For a record attempt we need a sunny day and high winds.

 

 

    

 

SOUTHBOUND

 

 

    

 

NORTHBOUND

 

 


For any Atlantic attempts we need to consider South and Northbound directions, in the case of the Swann, to test the craft with and without trade winds. These routes to be repeated with and without turbine assistance to be able to measure the difference that this particular design offers in various modes. This is with a view to adapting cargo and cruise liners of the future, where the IMO is frantically seeking 40% reductions of CO2 emissions before 2030.

 

 

 

 

PIONEERS - Louis Bleriot crossed the channel in 1909 from Calais to Dover. His flight took just over 30 minutes to cover the 24-mile distance. The Bleriot XI shares similar design qualities to the Elizabeth Swann, in being simple and light, including the cross bracing of the triangular tubed spaceframe that joins the front and rear cabins. Passenger variations of the Swann would feature a box-girder design to allow generous seating.

 

 

 

SPIRIT OF ST. LOUIS - An even bigger challenge beckoned in the Atlantic. Between May 20-21 1927, Charles Lindbergh completed the first non-stop flight across the Pond, from Long Island, New York, to Le Bourget, near Paris. His flight was sponsored by a group of businessmen in St. Louis, Missouri.

 

 

 

 

Wilbur and Orville Wright proved all the skeptics wrong with their Flyer I in 1903 at Kitty Hawk, North Carolina, USA.
