The San Diego Argonauts hosted a 19-day regatta at the Mission Bay Model Yacht Pond this month, with nine different boat classes of remote-controlled vessels and 175 model-yacht “sailors” from seven countries.  The pond, located at Vacation Lane near Sea World, also served as the host site to the International One Meter Class (IOM) boats — the fastest boats run by the best model-yacht racers in the world — drawing sailors from as far away as Canada, Brazil and New Zealand. The National Regatta is hosted by the San Diego Argonauts every three years.  This year, the club ran nine regattas, with seven of them racing for a National Title.  The best model-yacht sailors in the world attended the races and the competition was tough — but also a lot of fun for sailors and observers, said organizers. The Argonauts traditionally meet every Saturday at the pond for some thrilling sailing, said organizers.  Once a month, usually the first Saturday of the month, the Argonauts have scheduled races called Sail Points. The scores from these monthly races are kept and at the end of the year, awards are given out to the top three sailors of each class. The club races in the ODOMs, IOMs, Santa Barbaras and Soling 50 classes.  Club members said they would be happy to let guests and observers try their hand at sailing on non-race days.
