The Crimson placed third in the Mid-Atlantic championship racing at Annapolis yesterday. This robs the sailors of their chance to become East Coast champions, but leaves them the New England championship they gained the previous weekend.

Navy, sailing in home waters, took first place yesterday, running up 206 points. Cornell took second with 182, while Harvard had 172. M.I.T., who ranks second in New England, placed sixth out of the 11 entrants.

A college skipper, Jim Nathanson, made the second best individual score, with 91 points, finishing first in two of his races. The other Harvard skipper was John Bishop, Commodore.

Butch Horner was Bishop's crew, and Dean Howells, who had often crewed for Nathanson, was on his boat yesterday.
