In our earlier articles on this magnificent vessel, we showed you the conceptual development through several small scale models until finally the team were faced with actually building the full size craft - a mammoth task - as this is the largest solar boat (@ 4-10-12) in the world.


So how does one go about building something this big? The video below gives you the answer to that. With some trepidation, a lot of planning and elbow grease.


The 12.5 million euro Tūranor PlanetSolar now holds four naval records: 


  1. the fastest crossing of the atlantic ocean by solar boat (26 days 19 hours 10 minutes); 

  2. the longest distance ever covered by a solar electric vehicle; 

  3. the first circumnavigation achieved by solar craft (taking 1 year 7 months and 7 days); 

  4. and the fastest crossing of the south china sea by solar power (4 days 23 hours 45 minutes).

This magnificent boat (the full size one) entered the record books as the first electric boat to complete a (585 day) world circumnavigation. She arrived at the Hercule Harbour in Monaco on Friday the 4th of May at 2:15p.m.
