You're fortunate that the Windstar was designed to fit the International One Metre class, probably the most commonly sailed class in Europe, so there's a good chance that you might get an opportunity to sail in company.
You might want to try upgrading to alternative suits of sails (light/megium/high winds) etc. at a later date. If so http://www.housemartinsails.co.uk/ would be a good place to start.
