The RB-M is designed for multiple missions, including search and rescue; law enforcement; drug and migrant interdiction; and ports, waterways and coastal security. The boats feature increased speed, greater maneuverability, and a climate-controlled cabin and shock-mitigating seats to reduce crew fatigue on extended patrols.


  • Length: 45 feet
  • Beam: 14 feet, 7.75 inches
  • Draft: 3 feet, 4 inches
  • Displacement: 36,500 pounds
  • Maximum Speed: 42.5 knots

  • Endurance: one day


  • Deep-V, double-chine hull for a balance of speed and stability in various conditions
  • All-aluminum construction
  • Twin diesel engines with waterjet propulsion, eliminating propellers beneath the boat to protect the engines from debris and make it safer to retrieve someone from the water
  • Prominent fendering, which allows the boat to come alongside without risk of damage from bumping or shifting and frees the crew for other tasks
  • Self-righting stability (intact)
  • Port, starboard and aft recovery platforms
  • Fore and aft weapons mounts
  • Pilothouse with shock-mitigating seats for greater crew comfort and endurance
