SWATH - It all started with this tiny model, made of paper and cardboard. It floated perfectly as a submerged central hull, with outriggers just skimming the water surface, to provide stability.

 

In the years that followed a swing wing system and wind turbine boom were developed on a land vehicle. The idea is to combine a rotary sail generator with solar panels to allow faster blue water transits, allied to advanced computer navigation for green lanes.

 

 

The 'Elizabeth Swann' is an in-progress design study, under development, in the hope of defining a technical/cost compromise that will allow the vessel to beat the present water speed record for solar powered vessels.  For this we need minimum frontal areas in and out of the water, and superior hydro and aerodynamics.

 

There are 2 possible designs we are evaluating cost and complexity wise:

 

1. A single central submerged hull stabilized by outriggers - or Small Waterplane Area Triple Hull (SWATH).

 

2. A single central wave piercing hull stabilized by outriggers as a trimaran.

WAVE PIERCING HULL - In this CAD drawing the simple cylindrical hull design we started with has been revised to further reduce weight, air & water drag. The outrigger sponsons are ride height adjustable with a proprietary drag reducing system (not shown) that keeps them out of the sea for much of the time, further reducing water resistance.

 

 

 

V WINGS - CALM RUNNING - In calmer seas with a following wind and the sun overhead, the cantilevered sponsons may be lifted out of the water, with the V-foils. Small 4-point sailing craft benefit the most from hydrofoils, overcoming their speed/length ratio restrictions as they take to the air, also achieving speeds equivalent to wind speed. Whereas, larger craft reach twice wind speed for long periods, dependent on conditions.

 

 

 

 

 

TRIMARAN - The trimaran wave piercing hull design in plan view without solar panels or wings, is identical in general layout to the SWATH proposal except that the main, central hull is roughly half the diameter of the surface configuration.

FAITHFUL REPLICA - You can see from the 1:200 model, that the CAD version of the proposed design closely resembles the original concept.

 

 

 

Both of the proposed hull designs share the same:

 

a) Ultra light superstructure purposed designed to harvest energy from nature via b) and c) below,

 

b) Solar wings that track the sun and fold for storms, in concert with

 

c) A turbine generator on a mast that tracks wind conditions and furls for storms.
