RedactedNarrative: Vessel #1 reported that a jet ski was circling him and caused a wake that capsized his kayak. He lost several personal items including fishing gear, phone, GPS. He was unable to de-water the kayak and ultimately swam to shore with his kayak in tow. Once at shore he contacted the Police Department and Harbormaster. The officer notes in his report that the area he was kayaking has a high amount of boating traffic to include large ferries that transit to and from the Nantucket and Marthas Vineyard. It is possible the wakes generated from the surrounding vessels could have contributed to the capsize of the kayak. No further information was able to be obtained in regards to the jet ski or operator of the jet ski.
