ENTINEL
200-watt solar array, ideal for
running power-intensive sensors
and payloads. The monohull
version offers a more compact
profile and accommodates a 100-
watt solar array.
Despite its compact footprint, the
vessel is exceptionally efficient. It
consumes less than 5 watts to
cruise steadily at 2 knots (≈4
km/h), and reaches a top speed
of 4 knots on just 120 watts. At its
core is a custom immersible
motor with ultra-low KV for
direct-drive efficiency,
corrosion-resistant ceramic
bearings, and a vacuum-potted
stator and rotor to ensure long-
