Paul Stubing said this is a photograph of a Rhodes 19 sailboat named "Black Pearl".
This photo appears to have been taken from the Manset shore because the cape on Greenings Island is in the background. The Rhodes 19 has her sails up and she is alongside a float. Her sail # is 1012. There is a whaler tied to the head of the float and there are several rowboats overturned on the float. Moving towards the foreground, you see two bullseyes tied to the float. Each bullseye has its sails on but lowered. There is a male standing in the stern of one, looking at the Rhodes. This docking area seems to be what is now called Manset Yacht Service, formerly known as The Boathouse. Hinckley's dock is in the background.
