RedactedNarrative: The operator claims that he was going to shore from an island when he was just going up on plane when he struck rocks. He stated he hit hard enough to hit his head on the windshield. This and the resulting damage to the vessel did not support his claim that he was just coming up on plane. He attempted to continue down river until he realized he was rapidly taking on water. He beached the vessel just south of White Sands in Pembroke. Bow of vessel was in 6” of water, but stern sank in 3-4’ of water. The operator refused first aid and did not get a estimate of the damages. The estimate for vessel damages is from the vessel owner not an actual business estimate.
