Ben Fowke's Blue Phrog made it two in a row today in the Delta I class in the third race of Chesapeake Bay Race Week.

Carroll Buress Vitesse came in second again today. John Zeren's Mandala was third.

Today's racing put the 201-boat, 10-class fleet on a four-leg, 14-9 nautical-mile "round the buoys" course that started and finished at the mouth of Annapolis Channel.

Northwest winds of about 12 knots at the start gradually increased to 17 knots in the middle portion, with 22-knot gusts toward the end.

Goldfish, a one-ton boat owned by Allan Harquail and Don Zinn and competing in IOR B, was dismasted at the 10-foot-height soon after the boat cleared the first windward mark. There were no injuries. The mishap was apparently caused by the loss or failure of a retaining pin in the hydraulic backstay mechanism.

Today's race was sponsored by the Sailing Club of the Chesapeake.

The four-day competition will close Sunday with what race committee officials say will be the longest course ever used for Race Week. Depending on the wind, they plan to have the larger boats go around a 40-mile course, with the smaller vessels using a course about two-thirds that distance. Hans Schultz, race committee chairman for the race, said that some of the smaller boats would probably not finish until 8 p.m.
