¿De verdad que lo dices en serio? ¿Tu has cambiado una pala de timón alguna vez?

Creía que este hilo era serio.

Y lo es. Pero hay que leer las cosas con detenimiento. Copio y recalco lo que dice EL ARTICULO. EL ARTICULO que es lo que he traducido y resumido, y piensas que es de mi cosecha.

Proposed solutions: Pros & cons
Trackers: Tracking the disruptive pod is difficult and the trackers need to be renewed regularly. It’s costly and might not be very helpful as orcas can travel at up to 30 knots, covering large distances quickly.
Convoys: Escorted convoys could help boats through the most risky section, but would offer little actual defence in an encounter except offering safety in numbers.
Sonar: Acoustic Deterrent Devices (ADDs), also known as pingers, are used in fishing operations to warn off dolphins and porpoises from nets they might get tangled in. But the noise only becomes a deterrent once the animals learn to associate it with a risk, and the frequencies need to be tuned to the animal you want to ward away. Acoustic Harassment Devices (AHDs)
are used in Oil & Gas and Renewable industries to repel animals, but as well as questions over their effectiveness, cost and practicality, AHDs and ADDs need to be licensed to be used legally.
Shallows: Statistically there have been no attacks in the shallows, but this might be because few boats have hugged the coast while transiting the Strait. As more boats stick to 10m depths time will tell if this strategy works or not. Orcas are able to manoeuvre in shallow water and are known to chase prey into shallows, but it is a less clear acoustic environment.
Slapping the water: Slapping the water with a fin is thought to be a signal of irritation between some whale species, says Dr Todd. ‘A flat smack on the water with a large paddle could give them a signal to stop,’ though she points out this is untested, and shouldn’t be tried where there’s a risk of falling overboard or hitting an animal.
Fending off: ‘Deliberate disturbance’ is illegal, but might be arguable as justified if there is immediate risk to life of those on board.
Carry spares: Ensure you have the necessary tools for emergency steering, or even rudder replacement, if you lose your steering. A salvage tow is expensive.
