Ritchie BN-202 Navigator Compass - Bulkhead Mount - Black

The Ritchie BN-202 Navigator Compass with bulkhead mount in black is a 4.5-inch marine compass designed for vessel navigation and directional reference in maritime operations. Built on Ritchie's proven CombiDial system, this compass combines traditional heading indication with an integrated inclinometer, making it an essential navigation tool for boat operators, marine professionals, and tactical water-based teams requiring reliable compass performance in dynamic offshore environments.

The internal gimbal suspension system maintains level reading even as vessel attitude changes, critical for maintaining navigational accuracy during transit or recovery operations. The bulkhead mounting configuration fits a 5.75-inch hole and requires proper alignment—the compass must be mounted perpendicular to the vessel's centerline and vertical to the waterline when the boat is on level keel; fairing blocks are mandatory if the mounting surface deviates from these specifications. The 7 x 7 x 8-inch footprint and 2.8-pound weight integrate cleanly into most vessel mounting schemes without requiring structural reinforcement or extensive electrical infrastructure.

This compass suits boat captains, Coast Guard personnel, maritime rescue teams, and operators managing offshore patrol or interdiction missions where dead reckoning and backup navigation are mission-critical. The integrated inclinometer serves dual purpose—tracking vessel heel during maneuvers and providing slope reference data useful in tactical situational assessment. Ritchie compasses are standard equipment across U.S. Navy vessels and commercial maritime fleets, ensuring compatibility with established navigation protocols and operator familiarity across diverse maritime operations.
