THE ELIZABETH SWAN - The graceful lines of this beautiful solar powered boat complements the zero carbon cruising ideal that many designers and United Nations planners aspire to under SDG13.
A 1:20th scale test tank model of the Elizabeth Swan, Queen of the Seas, is under construction. For the SNAV, Elizabeth Swann, development models we will use triple layer, laminated, amorphous cells in combination with polycrystalline (16.5 - 17%) cells to provide 100+ watts of energy for hull speed tests.
The full size vessel could achieve a superior power to weight ratio as kilowatts per ton, but is being limited to 67kW (55kW + 12kW) on economic grounds, so around 2.8kW/ton at present displacement estimates for the smaller turbines setup, and 90kW (60kW + 30kW) for the larger turbine installation, to give 3.4kW/ton. 100w on this model is the equivalent of between 3.73kW/ton (5hp) - 5.89 kW/ton (7.9hp), depending on the weight of the final model.
The model is therefore more powerful than the full size ship pro-rata, when it should perhaps be the other way around - and of course it is, because the model should have a considerable battery mass and it has none. Ballasted (lead weights) the power to weight ratio is roughly 5.27kW/ton (7.07hp) in the upper range. Or, looking at it another way, the full size ship may prove to be faster than we are working towards giving us a respectable safety margin.
The world record at the moment is held by Planetsolar, a ship that weighs 95 tons and generates 93.5kW from 825 solar panels. That works out to .984kW per ton. For this reason the Bluefish platform promises to advance the state of the art significantly in theory. That coupled to the stable low drag hull, could yield sprint speeds in excess of 18 knots with suitable motors, and that is why this is an exciting time for us. When built the Bluefish hull will be the largest solar powered boat in the world at 43 meters (140ft). Planetsolar is 113 ft long and the current record holder.
For 2021, the Kulo Luna story is undergoing conversion for the possibility of publication of a Special Edition graphic novel, by artists in the Sussex, London and around the UK.
This edition is condensed for a quicker visual experience with 5 chapters as 24 scenes:-
The Elizabeth Swan is an advanced boat inherited and completed by John Storm in time to enter the worlds first solar circumnavigation race starting and ending in Hawaii. This is a fictional adventure story intended to increase ocean awareness. The Swan is said to be the world's fastest solar powered vessel with twin solar arrays that track the sun and quad wind turbines (draft specification subject to change) as the power source; all harvesting free energy from nature.
Other features that increase performance of this innovative vessel are the onboard robotics and active hull. The Swan is a 6 berth ocean cruiser that can make fast, zero carbon, passages across the Atlantic, Indian and Pacific oceans, adding spice to the adventures of our conservationist hero.
Where John Storm is a fictional character, the Elizabeth Swan is a real concept boat in the making, looking to run the 'Sunshine Route' gauntlet and push the boundaries forward to herald a new age of clean yachting and cargo transport.
THE PELICAN - Having part filled the ship with treasure, Francis Drake renamed his ship the Golden Hind. He set sail with the Elizabeth, Swan, Christopher and Marigold. The circumnavigation took almost three years. Jules Verne proposed a world expedition in under 80 days for the fictional character Phileas Fogg.
It is an interesting historical fact that on 13th December 1577, Francis Drake left Plymouth Sound with five ships on a voyage of discovery part funded by Queen Elizabeth I, the first circumnavigation by an Englishman:
The Pelican (renamed The Golden Hind half way through the voyage) The Christopher The Elizabeth The Marigold The Swan
Queen Elizabeth I, gave Drake a charter to attack and loot other vessels, most particularly, Spanish ships. The venture was a great success, allowing the Queen to pay off her debts and invest the substantial profits in other enterprises.
KULO LUNA - Is the story of a giant humpback whale and her friend Kana, who is killed by pirate whalers in the south pacific ocean. Enraged by the death of the young whale, Kulo attacks the pirate ship, finally sinking it, but getting herself wounded in the process.
A Japanese cartel put a $multi-million dollar bounty on her head, when another whaling ship gives chase. Before not too long the media hear of the hunt and betting begins all around the world. At this point our hero, Johnny Storm, abandons a solar boat race to try and help the whale where his boat, the Elizabeth Swan, is not far away from the last sighting.
John rescues Kulo from being eaten by sharks, but that is just the beginning of their adventure, as the pirates whalers close in for the kill ........
SUPERB - Keira Knightly portrays Elizabeth Swann as the girl who grew up with a thing for pirates and then fell in love with one - and his swashbuckling lifestyle.
The Elizabeth Swan has an active hull that for the main part rides under the water to reduce wave and skin friction drag. Above the water, robotics control the energy harvesting apparatus to maximize the efficiency of a relatively small collection area. The Swan was named after Elizabeth Swann, the fictional character in Disney's Pirates of the Caribbean series of adventure films played by Kiera Knightley.
PROTEST - The People's Climate March (also called People's Climate Movement) was a protest which took place on Washington, D.C.'s National Mall, and among 300 locations throughout the United States, and locations outside the U.S., on April 29, 2017.
Organizers announced the demonstration in January 2017 to protest the environmental policies of U.S. President Donald Trump and his administration. The protests were held at the end of his first 100 days as president, during stormy weather across the U.S. There were an estimated 200,000 participating in the D.C. march.
DUAL HELMS - You can live on board this blue water cruising craft in comfort with relatively little cabin space. The Swan boats two helm positions, one fully enclosed at the front for rough weather sailing and one open deck at the back for sunning yourself in fine conditions, for fishing and with diving ladders water sports.
ACTIVE HULL - With a SWATH hull design reserve buoyancy becomes an important consideration. With an active hull the reserves are increased dramatically. SWATH is the acronym for Small Waterplane Area Triple Hull. When in fact the two outriggers may be lifted out of the water completely in ideal conditions and lowered to cope with cargo carrying where the recommended limits have been exceeded, in times of emergency.
TEST TANK MODEL - A model of the Elizabeth Swan under construction, to be used for test tank and open water trials. In this picture you see the solar wings before fitting to the main hull. The rights to this design have now been acquired by Jameson Hunter for the Kulo Luna novel.
SOLAR COUSINS - Raphaël Domjan has long been an advocate of renewable energy, finally realising his dream in 2005, when he set up an association with people able to help him develop the PlanetSolar project, one of which was Immo Stroeher, a German entrepreneur who backed PlanetSolar from 2008. Five years later, a catamaran 35 metres long, 23 metres wide, with solar panels covering a surface of 537 m2 was launched.
With a crew of three, Raphaël set sail at the helm of 'his' solar boat on 27 September 2010, heading west in search of the sun. PlanetSolar returned with its Swiss skipper to 'le Rocher' on 4 May 2012 to complete the first solar-powered voyage around the world in 584 days. This was a stunning world a record first and a milestone for solar powered marine transport. Due to her advanced design, the Elizabeth Swan holds the potential to reduce a solar powered circumnavigation (Guinness World Record) to well under 250 days.
Raphaël is pictured here in the recently built robotics laboratory in Sussex, England where SeaVax, also a solar (and wind) powered vessel, is being developed as an ocean cleaning workboat. Copyright photograph © Cleaner Ocean Foundation August 25 2017.
ROBOTICS - Ryan Dusart is keen on robots. He is also learning about hull design, in helping to take this wooden test piece to a fully working 1/20th scale tank test model. Copyright photographs © 18 November 2018 Cleaner Ocean Foundation Ltd. All rights reserved.
MARKING & CUTTING - Aluminium is a useful metal for building workboats because it is lighter than steel, does not corrode and can be cut, formed and welding relatively easily. In these pictures young Ryan us marking out a bulkhead using a paper template, then cutting using a DeWalt battery jigsaw, that is very handy in any workshop to reduce potentially dangerous cables.

FOLDING - Flat sheets of metal have no strength. By folding the edges, and is some cases including corrugations, what was bendy and unable to take loads suddenly becomes rigid and load bearing. Copyright photographs © Cleaner Ocean Foundation Ltd. All rights reserved.
TEST FIT - The first of four bulkheads is offered up for size - and it's a perfect fit. If you make a part that is not quite right, you can fettle it a little until it slots into place. If the part is well out of tolerance, just start again and be more careful in your lofting. Copyright photographs 18 November 2018 © Cleaner Ocean Foundation Ltd. All rights reserved.
