Safety
The RIB 450 Patrol is designed for commercial operators who need a boat that will work every day without complaint — dive charter companies running multiple trips, coastguard auxiliaries conducting search and rescue, harbour pilots transferring to ships in all weather, and offshore service teams deploying personnel and light cargo. Its aluminium hull shrugs off impacts that would damage fibreglass, making it a long-term investment for demanding fleets.
Professional marine units need a rugged, high-speed boat that operates in extreme sea conditions and can carry mission-specific equipment.
