Compact, Self-Righting, Efficient

A truly enabling ASV platform, allowing researchers quick deployment with as little as a single-person field crew - readily launched through consistently plunging breakers and able to collect high resolution sounding data within minutes of arriving on site. Recovery through the same swash conditions is as easy as switching into manual mode, timing a wave and riding it ashore to a controlled grounding. 

Hull Type

Compact, narrow-beam, semi displacement, low drag, passive self-righting hull constructed from advanced composites for maximum durability, impact resistance and field serviceability.
Designed specifically for efficient operation at survey speeds (~2m/s) 

Sensor Payload

Payload elements are highly integrated into the hull and need to be specified at the time of ordering,

Single Beam Echosounder

Cerulean S500 or Echologger ECS (200/450 kHz)
Integrated to onboard data acquisition with future upgrades allowing real-time depth telemetry to Operator Basestation


Emlid Reach M2
cm-level GNSS with dual-band support (L1/L2) PPK
RTK support integrated to Cerulean S500 when equipped

Integrated IMU

Attitude (roll, pitch) measured by Ardupilot
The Z location used for heave compensation / water level measurement used to calculate wave heights, tidal water levels or surge.

Measured Accuracy

 3-5 cm (PPK GPS)  vessel XYZ position relative to NAD83/NAVD88  or user-selected datum
Approx. 5 cm RMSEz compared to GPS pole mount measurements
2 cm RMSE3  or ± 10 cm maximum error when track lines are sampled similarly with equipment and methods established by U.S. Government Agencies (USACE)
3Interpolation between track lines introduces a substantial error component in reconstructing bathymetric surfaces from SBES data and is therefore dependent on track spacing.
