Marine 4 is a 1999 Maycraft 22-foot fiberglass hull boat powered by a Johnson 225 HP OceanPro outboard motor, with an additional 15 HP Evinrude trolling motor for maneuverability. The vessel is equipped with a 20 HP portable high-volume fire pump capable of delivering 500 GPM, making it a vital resource for marine firefighting operations.
Navigation and situational awareness are enhanced by a Garmin GPSmap 741XS HD-ID sonar system, an Automated Identification System (AIS), and a VHF radio. The unit also carries a FLIR thermal handheld monocular camera to aid in search and rescue operations. In addition to firefighting and navigation capabilities, Marine 4-1 is stocked with EMS and rescue equipment, allowing crews to provide patient care and perform water rescues as needed.
