RedactedNarrative: Traveling from the New Hampshire side of the Piscataqua River Vessel 1 rolled, swamped, and sank. Vessel 1 had a wooden floor, and the operator thought there was water collecting under the floor which caused the boat to roll on its side and shift in weight. Vessel 1 was never recovered. Individuals were picked up by good Samaritans transiting the river.
