orcas attacks... which protection for rudder and fins on trawlers?

No wonder orcas do not like the great lakes.

I can't find the "thumb" in this new site design, otherwise I would give it one.

@JDCAVE : yes of course, Dean Yule ( Keypower ) would like also to know how fins on starboard and portside will perform with these small spikes ( 2 cms) screwed with 4 mm in the solid part of the polyurethane material. As well, easy to remove underwater. I will of course make the report.I hope this will discourage orcas to push the fin with their nose creating the pressure required to broke it. I do not pay attention to the blablah of green lobbies and pseudo scientists who cry and talk and talk, but do not own yachts or trawlers, or do not go out from their marinas

No more drama or high anxiety on this topic since January, what’s happened?

Has the novelty worn off, or has it become so common it is no longer worth mentioning?

Orcas have a full belly.
They will come back for seconds later.

New attacks near Fisterra and la Coruna this month infortunately. Go to Orcas attack Facebook group to learn more.
I did a passage 15 days ago offshore through Biscay bay from La Coruna, Spain to Royan, on the french atlantic coast. 52 hours. We saw dolphins but no orcas. Difficult to say if spikes bolded on the Keypower stabilizers fins were useful or not. I noticed loss of one knot during the transit with an acceptable weather and seastate in this very exposed area to swell and strong winds, may be currents or fouling

Gotta wonder if compressed air discharge behind the rudders would do the trick. Especially with a divergent nozzle. Increases noise substantially.
