The latest vessel commissioned for the Truex clamming fleet is outfitted with a suite of Simrad Commercial marine electronics.

Simrad Commercial, in partnership with Patti Marine Enterprises, has supplied two Simrad NSO evo2 processors driving five 18.5-inch monitors, an AP70 Autopilot, Halo-4 and Halo-6 Pulse Compression Radar systems and two SonarHub sonar processing systems to the SEAWATCHER II.
Leif Ottosson, CEO of Navico, which owns Simrad, said: “Outfitting a state-of-the art clamming vessel of this size requires the most advanced electronics to produce the results that will deliver the best return on investment. With Simrad, our goal is to give the SEAWATCHER II confidence to head offshore knowing they will have safe and productive journeys.”
The 152-foot SEAWATCHER II is the first ABS-class clamming vessel ever constructed and was designed to carry nearly 200 cages of fresh clams. It will use the NSO evo2 processors multi-function display system, designed for boats 10m or longer, for integrated charting, echosounder, radar and autopilot purposes.
The Simrad AP70 combines an adaptive auto-steering system with a user interface designed by captains for captains, while a solid-state, open-array radar system with pulse compression technology is offered by the Simrad Halo Pulse Compression Radar.
Combining the advantages of Broadband Radar and traditional pulse radar systems, Halo provides navigational visibility and awareness, as close as 20-feet, within the pulse radar’s short-range ‘blind spot’. It also offers long-range performance up to 72 nautical miles.
SonarHub’s CHIRP sonar provides high-definition detail to depths of 3,500 feet; while StructureScan HD functionality delivers a picture-like view to the sides and beneath a vessel to help locate potential fishing and clamming areas.
