Aluminum Catamarans

High speed, ocean class & spacious

Long, narrow hulls for speed & efficiency


Long recognized for their stability, catamarans have a softer and more comfortable ride than comparable monohulls. In addition, catamarans are typically wider than conventional monohulls and offer excellent use of below-deck hull space for berthing and other amenities.

These boats are perfect for:

  • family cruising
  • sport fishing
  • commercial fishing
  • whale watching
  • survey boats
  • charter fishing
  • dive boats
  • patrol and law enforcement
  • passenger vessels
