Growing in long strands upward from its roots in the sediment and branching out profusely at the surface, the plant creates dense curtains and mats of vines, tangling boat propellers, tripping up wake boarders, snagging water-skiers and frightening off swimmers.
Whereas ship propellers typically have efficiencies around 60%, and aircraft propellers up to around 80% (achieving 88% in the human-powered Gossamer Condor), much higher efficiencies, in the range of 96% 98%, can be achieved with an oscillating flexible foil, like a fish tail or bird wing.
Her two diesel engines moved her at up to 9 knots on the surface, while her twin electric motors propeller her at up to 7.5 knots while underwater.
(The police also brought a helicopter, but feared that the wind from its propeller might end up weaponizing the floating ice shards).
