Who this publication applies to

This instruction applies to all equipment categorized as service craft and combatant craft in reference (a) and all bo ats, except for watercraft operated by Naval Special Warfare. Note: This “note” provides a “boats” definition section for completeness during the transition of reference (a). Navy boats are self-powered waterborne craft, not specifically designed as combatant craft, which range from small outboard engine powered ut ility boats to large non-commissioned watercraft (e.g., range support craft), are suitable primarily to be carried aboard ships and to operate in and around naval activities or other safe haven. Large boats are a subcategory of boat with lengths of 85 feet and greater.
