The Bermuda Sloop Foundation is challenging students to work out when the Spirit of Bermuda will cross the finish line of the Marion-Bermuda Race.Participants will be asked to plot the Spirit’s daily position and estimate the date and time of the vessel’s finish.Denise Riviere, CEO of the Sloop Foundation, said: “The idea is to get students engaged in the excitement of the race and use some of their math and geography skills. They are going to have to consider things like speed, wind direction, sea state and more.”Two winners - one secondary student and one middle school student - will win a two-hour day sail on board the Spirit of Bermuda along with some merchandise.Any interested Bermudian students between the age of 11 and 18 are asked to visit www.bermudasloop.org and download the Contest Instruction Packet.They must then solve the problem on their own, showing all their working, and entries must be submitted either at the Sloop Foundation’s offices at 12 Wesley Street or sent by e-mail to info@bermudasloop.org by noon on June 17.
