RedactedNarrative: Operator was at full throttle heading South in Oyster Bay Harbor heading back to the Sagamore Yacht Club sailing schools floating dock when he looked away for a few seconds and when he faced forward again he couldn't avoid the collision with the sailing vessel which was heading north to then tack into the wind. The collision occurred on the port side of the boston whaler and the port side of the sailing vessel. The whaler ramped up and made contact with the spreader cable which cut through the fiberglass hull of the vessel and sent a wood compartment cover flying off of the vessel.
