RedactedNarrative: V1 was traveling East into Charlotte Harbor just outside Turtle Bay. At approximately 9:00 pm, V1 started taking on water over the stern from strong winds and heavy rain. They were unable to keep up with the incoming water, due to failure of the bilge pumps. At 9:30 pm all 4 occupants dawned PFD's and entered into the water. They swam to a nearby sand bar where they were rescued by a good Samaritan shortly after. There were no injuries to the occupants.
