Needlenose
Portable, Self-Righting, Expandable
Designed from the ground-up for challenging surf-zone research activities. with payload capability that supports advanced MBES & Swath Bathy in a DC drive / Jet propulsion configuration that produces no wake in slow speed displacement mode.
2 person launch and recovery operation
Readily transported on a roof rack or pick-up truck bed.
Mobilization to remote beaches possible with a manual trailer or dolly (<500m typ.)
Self-righting hull design with accommodations for user-expanded payload
Agile with reserve power to quickly plane for beach launch and recovery through breaking waves
Completely sealed & unsinkable with foam buoyancy
Hull Type
Self-righting wave-piercing nose rounded bottom hull for smooth efficient running through chop
Constructed from advanced composites for maximum durability, impact resistance and field serviceability
Sensor Payload
Tested extensively with a Ping DSP bathymetric sidescan and supports a wide variety of SBES, MBES, ADCP, CTD, Sidescan, Survey grade GNSS/INS, and other sensors, samplers and cameras (contact factory).
Payload elements can be added, modified, substituted or removed by client to suit specific mission requirements, up to a maximum of 30 lbs (14kg) with considerations on the effects of drag on stability, agility and endurance.
