Vessel 1 was sailing in a northerly direction in Stonington Harbor on starboard tack. Vessel 2 was sailing in a southerly direction in Stonington Harbor on port tack and collided with vessel 1. Vessel 2 attempted to yield to vessel 1 however while in close quarters the lookout on vessel 1 yelled "come up". The operators of both vessels thought the instruction was for them and the vessels collided. Both vessels were in  a sailboat race and at the starting line sailing for a good position across the line.
