Notes:  Specifications subject to change without notice

1:  Dimensions are the base vessel without attached sensors or sensor mounting points2:  Max payload varies depending on weight distribution. Contact ICS for details3:  Operating > 25 degrees may starve engine of oil, non-operational tipping > 30 deg can compromise carbon fuel canister4:  87 Octane (R+M)/2 (90 RON) or higher; Max 10% Ethanol / 15% MTBD. Do not add oil to gasoline; E15, E20 and E85 blends are NOT approved and should NOT be used. A fuel stabilizer is recommended to keep fuel fresh, prevent deposits and metal corrosion from alcohol & MTBE reactions.5:  Wireless range is typical with the antennae provided, and is dependent on base station antenna height, local interference, and line of sight6:  Temperature range specified represents actual field-proven conditions; higher and lower operating temperatures are possible - consult factory7:  Max speed assumes no drag inducing sensors and is taken at 130 lb payload load; de-rates to 8kt @ 280lb8:  Min speed taken with centrifugal clutch present, deployment at lower speeds possible - consult factory9:  Mission endurance depends on overall payload, effect of drag-inducing sensors, energetic waters & operating speed10:  RTK position accuracy relative to a stationary RTK Base + 1 PPM; dependent on GNSS constellation
