Boat operator was transitting from Iay Bay to Plieades Island, a familiar course. He veered off course due to an approaching vessel coming ahead from the north. As he approached the destination, he saw the bottom coming up fast. He cut power and put boat into neutral. Started to adjust finder setting from 1500 ft depts to get clearer reading. Within 10 seconds he hit a rock. Both props, rutters, shafts were damaged. The Coast Guard Cutter Long Island assisted him back to Valdez for repairs.
