The organizers of the Frisian Solar Challenge changed the stability criteria in their rules for the 2010 race. As none of our teams have started building their boat yet, we thought we could still change our rules accordingly, so that the boats you build are in line with the Frisian Solar Challenge criteria, in case you want to take part next year!

However, to approve this modification to our rules, we would like everyone to confirm that they agree with it, before the 9th July…..

Here are the details of the modification:
Instead of:

” 5 – Stability: The stability of the vessels must be such that: a mas of 10% of the total mass of the vessel without the crew members in a position on the outer edge of the vessel, and with the crew member(s) in their normal position, will not result in lean over exceeding 15 degrees. In that case none of the openings in the hull, such as the outlet opening of the bilge-pump(s) and the deck edge maye be submerged below the waterline.”  According to the 2008 rules

We’ll have:

” 5- The stability of the vessels must be such that a prescribed rolling moment of 150 Nm applied to the vessel with the vessel loaded with a load of 50 kg at the location of seat of the skipper, will not result in lean over exceeding 12.5 degrees.” According to the new 2010 rules

The Team Barco Solar UFSC went to the Polo Náutico on Wednesday to pick up their catamaran. It is the first team to receive its boat, although two more boats are ready. The teams who are receiving the catamaran will be responsible for designing the connection between the two hulls of the boat, and the whole electric system.

We will be giving more information about the solar panels soon. Please come back for more news next week!

The organizers of the Frisian Solar Challenge announced that the race will now be called The World Cup for Solar Powered Boats. Their press release mentions Brazil as one of the countries where similar races now take place, as well as Germany, France and Italy.

Registration closed on the 30th June. We now have 19 participants, with the last team to register, the TecNaval team, made up of students from the course for naval industry technicians run by the Polo Náutico da UFRJ.

We have defined the area in which the race will take place, in the Paraty bay. We want to make the most of the bay but do not want participants to adventure themselves far out in the open sea. So we’ve created an imaginary line that delimits the area where the race will take place: it is a straight line going from the end of Tarituba beach to ‘Ilha deserta’. The stages of the race, one per day, will be of approximately 40km. They will be revealed the day before, as they might change according to wind, sea, and sun conditions…
