Elizabeth Swann SUNSHINE ROUTE

The table below shows average insolation between waypoints of the 'Sunshine Route' for one example. These are estimates based on reliable geographical data and the successful circumnavigation by PlanetSolar in 2012.
World insolation figures are available for many positions on earth, but not for the open ocean. There are many variables, for example the efficiency of your solar cells, and whether or not tracking is incorporated.
We have elected to build the Elizabeth Swan as economically as possible - and that means no exotic materials. This decision also makes us more attractive to project partners - and validates the commercial possibilities for solar powered cargo ships and cruise liners.
Navigation is to take advantage of trade winds and currents wherever practical.
RECORD "SUNSHINE" ROUTE
CLIMATE CHANGE CHALLENGE - The above table illustrates one of the most likely ocean awareness expedition routes, known as the 'Sunshine Route,' showing the time elapsed in days for 7 knots average cruising speed, including times for 5 and 6 knot averages - allowing for 10% downtime and 36 days in ports. Hence, although the objective is to reduce the current solar circumnavigation record from 584 days, the event in not an outright non-stop yacht competition in the offshore racing sense. It remains to be seen how accurate such a prediction might be. In this table we only allowed 36 days for provisioning and PR but added a 10% contingency for servicing, that could be used for additional time in ports. As a Climate Changing event, performance is one of the main criteria, especially concerning the possibilities for a transition to low carbon shipping and the contribution this might make in combating global warming.

STABILIZED MONOHULL - The diesel powered Cable and Wireless Adventurer was built for the purpose of circumnavigating the world in less than 80 days. This was successfully accomplished in July 1998 in 74 days, 20 hours, 58 minutes, traveling more than 22,600 nautical miles (26,000 miles or 41,855 km). This achievement set a new Guinness World Record for a diesel powered vessel. The nautical mile or knot, is a unit of speed equal to approximately 1.15078 miles per hour on land (1.852 km).
GUINNESS BOOK OF RECORDS - MS Turanor PlanetSolar (Switzerland) navigated the world in a westward direction from Monaco in 1 year 7 months and 7 days from 27 September 2010 to 4 May 2012. We wonder why nobody has attempted to improve on this design, to challenge the record in the intervening seven years.
