The fourth and concluding race of the series was sailed on the next day, August 5, around a triangular course. The breeze was still southwest with a velocity of about twelve and a half miles an hour at the start. This race was around a triangular course, ten miles to a leg, the first course being to windward, directly southwest, the second leg cast by south, a reach, and the final leg north by west one-half west, another reach. Near the windward mark the breeze got up to close to twenty statute miles an hour but faded off toward the second mark. At the finish it was sixteen statute miles an hour.

This was the race in which Endeavour II established a new record in that she was the first cup yacht on record to have crossed the starting line ahead of the gun and was recalled to start over again. For seven or eight minutes before the start, there was a regular dog fight around the starting line between the two big yachts which were being sailed more like Frostbite dinghies. Each gibed, tacked and spun around for all the world like two small class boats. At the start, both were on the starboard tack with Endeavour II ahead and slightly to leeward. However, she was early and her nine second lead at this point cost her one minute and fifteen seconds as she had to swing hack around the buoy and again cross the line. The remarkable thing was that she did not lose more time.
