Commercial fishing vessels operate in some of the most demanding conditions at sea. You and your engine are dealing with 12+ hour days, heavy loads, harsh weather and tight seasonal windows. When the season is open, downtime isn’t an option. Cat® Marine propulsion engines, auxiliary engines and generator sets are built to help you maximize uptime, manage fuel burn and plan service around the way your fishing fleet works. Caterpillar helps keep your vessels running from deep-sea fishing grounds and aquafarming operations to busy harbor waters.
