Orca bites off rudder ....

What about lowering a waterproof loudspeaker into the sea and playing ABBA/Deathmetal/Holst/Theme from Jaws??
Or simply banging with a hammer a metal pole dipped into the water . This is how the Japanese and Faroese terrify small toothed whales and dolphins ( including occasionally orca ) into bays in order to hack them to death and flog the babies to dolphinariums .

Or ask the Faroese to do a one off away event?
 
Told you skegs were so yesterday. What they really needed was a dual spade setup where you always have a backup… oh wait.

this is an Amel 50 that was played with off Portugal. They could still steer and made it back to port in Spain and had the boat lifted. Amel installed two new rudders and a drive arm overnight and the boat splashed again the next day.

I have only ever heard good things about Amel’s customer service.

if I remember correctly once Amel heard about the damage they chucked two rudders and tools into a van and drove to Spain(?), met the boat as it arrived and spent the night removing and reinstalling the rudders and one bent autopilot arm. Fantastic customer service. Mind you, you are paying for it but I wouldn’t complain.
 
Why the rudders always? Do they try the keels ever?

Might they be treating the boats as intruders
I'm fairly sure they know exactly what they are doing. With their echo location skills they may be able to see inside a rudder and just like the monkeys of longleat know exactly how to spoil your day without much effort.
I'm sure they could easily rip a keel off or damage it enough to sink a boat, but they don't.
How many keels could withstand 5 tons side impact at up to 30 knts? Don't p*ss them off!

How many whales can survive hitting a keel at 30 kts with their head? If they are clever they won't be doing that!

Not a problem for a whale; their internal anatomy includes a large fluid-filled organ in the head (the "melon"), whose primary function is to focus sonar pulses, but which also acts as a shock absorber. Killer whales (Orca is deprecated by scientists, as there may be several species) use ramming as part of their hunting repertoire.
 
I wonder how long it takes to work out if they bash the hull instead, that a short while later a small round boat is inflated with lots of easily accessible, tasty food in it.
They did that to a wooden boat mid Pacific. They swam off once they saw the occupants were safely in their liferaft ?
 
People (experts) keep telling us how intelligent these creatures are.
If that is correct then the theory that they are attacking boats for food is surely a dispelled myth by now.
They've tasted enough GRP now to realise it's not edible so where is the "intelligent" learning process.
They are clearly not trying to eat the boat, they are attacking to damage it, it would seem.
In any other walk of life, an animal attacking and endangering human life would have been culled.
Too late now though. They're all at it.

Maybe they want their play park back

Hard to definitively say what the motive is and it seems unlikely that orcas have any concept of 'damage' as relating to material objects. Possibly they are mistaking yachts for other living creatures, or possibly the rudders just break with a satisfying crunch! Lots of human behaviour does not have any obvious functional value to the participant (recreational sailing being a case in point) and would similarly puzzle an orca humanologist. In highly intelligent, social species these behaviours can be explained as either building skills that do have survival value (e.g. play) or the misdirected action of an imperative that at some point did have survival value. Culling would probably be an overreaction (though possibly I would feel differently if my boat was damaged). Certainly some research on effective deterrents would seem worthwhile.
