In one of the key contests of the season, the varsity sailing team will face eleven other schools in the Eastern Dinghy Championships tomorrow and Sunday at Annapolis.

Other teams competing in the regatta are Army, Brown, Coast Guard, Cornell, Dartmouth, Navy, Penn, Princeton, Yale and Williams. Hanson Robbins and Jim Parker will skipper the two Crimson boats.

Racing on the Thames River, four Crimson yachtsmen will compete in another regatta tomorrow at Coast Guard. Co-skippers Dave Gill and Larry Snide-man will race against Boston University, Coast Guard, Holy Cross, MIT, Providence and Wesleyan.

The teams will race in Raven class sloops, which carry spinnakers. These boats are more difficult to handle than the dinghies used in most intercollegiate races and should test the skippers' ability to handle the added sail.

Next weekend the Crimson sailors will race against eight other teams in the finals of the New England Intercollegiate Sailing Association Championships at Coast Guard. The varsity qualfied for the meet last Saturday in the first round of the competition at Brown.
