RedactedNarrative: The operator of the rented vessel stated that the tube with rope that was stored on board the vessel by the marina was not stored properly and flew off the back of the vessel and got tangled into the prop. The vessel drifted into rocks near the shore while untangling rope from the prop. Once prop was freed the operator back away from the shore and hit another rock. The marina had fixed and boxed the part before Marine Patrol could investigate and take pictures.
