Queen of the Seas, Elizabeth Swann


WWSR - Small development model 1:200 scale - Elizabeth Swann



Amid the IMO's 'dash' to green shipping, the concept of a fast blue-water, energy-autonomous vessel draws tantalizingly close. Though not something cruise or cargo vessel operators are likely to embrace in the near future, with super fuels being developed such as Ammonia, LNG and Methanol, the Cleaner Ocean Foundation is looking to develop the considerable potential of such disruptive technology, where red flag braking from the dirty diesel brigade is lessening.


The general characteristics of the concept may be adapted for inland waterways, rivers, cross channel and inter island-hopping transports, or luxury zero carbon yachting. As a research vehicle, data collected as to use with and without a wind turbine, will be useful in terms of ZC, green shipping of the future, effectively a series of determinative experiments - either way - valuable data for sharing.


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.



Solar and wind powered hybrids are the fashion at the moment. For ocean work, a large solar panel area in relation to hull displacement is essential to generate sufficient energy for dependable transits. When the sun is not shining at night, a wind turbine supplements hull thrust. The advantage of a moveable turbine over sails is vector angle conversion, where winds from dead-ahead and beam-on translate to forward thrust without the need to tack, and no shading of solar panels. This is combined with a suitable hull Speed Length Ratio to even out troughs and peaks.



Ryan Dusart, zero carbon advocate


YOUNG ENGINEER: I'm twelve at the moment, when I'm fifteen in 2023 I may be the youngest crew member of an attempt to beat the English Channel crossing record in a solar powered boat. Imagine that, setting a Guinness World Record. My Mum is a Foundation Trustee and my auntie is a paramedic and RNLI volunteer. I hope I can contribute as much as they do during my life, in combating climate change and saving lives. I'm helping to build the 1:20th model of the Elizabeth Swann seen below.



Thought leaders look to advance knowledge, pursued in the real world by a select few innovators, who forge ahead unfettered by the chains of tradition - and sometimes just to prove a point.


As we progressed from sails, to coal-fired steam-driven paddles, to diesel powered propellers and nuclear powered warships, we created a shameful pollution legacy. Today, the United Nations boast sustainability agendas aimed at reversing the trend.






1:20 SCALE - The model under construction, first in wood to check the angles of working of the active sponsons, then in aluminium. Before any of these stages, an adjustable jig had to be built to ensure the alignment of the parts.




The Elizabeth Swann is an extraordinary design, incorporating many innovative features, progressing as a shining ray of hope for a world where our melting ice caps are restored and oceans might become acid free; once again full of healthy fisheries and happy marine mammals.


Much of the Swann concept shares parts/technology commonality with the SeaVax ocean cleaning machines. Hence, the Swann project contributes to that concept.


Join us if you will for a voyage into the nautical unknown where the Queen of the Seas is a zero carbon vessel that harvests the energy it needs for propulsion - from nature - as a leading edge project with multiple facets.



Hydraulic power pack inside the Ford Transit van


FLUID POWER - The solar wings and raising of the wind-turbine mast is accomplished using electro-hydraulic power packs, hydraulic rams and motors.





With the help of an engineering student from Belgium, the Foundation funded the development of a test rig designed to improve knowledge of the proposed wind turbine mast and folding solar wings. A humble Ford Transit was the donor vehicle.



Water test tank and wind machines


WATER BASIN - This compact unit re-circulates water using vanes and pumps that are put into the tank for drag and wave tests. The tank can be emptied and refilled in forty minutes. Twenty minutes for each transfer to and from an underground holding tank. This unit is ideal for low cost conceptualization, before detailed CFD, or other development.





The next phase of development is to complete a 1:20 model for stability and floatation testing in our water basin (above). Note the fans to simulate cross winds in rough seas, where the Elizabeth Swann has a rotary sail and wings of considerable span that could generate significant roll for a hull that is unable to compensate for a harsh environment.
