Otter proofing fenders

[mbowers]

I was wondering how my boat lift sustained damaged after months of no issues with fenders in place. I added some more fenders thinking it was my fault. This morning I noticed the damage was probably caused by an otter pulling the very fender I thought wasn't enough on to the dock! Security cam footage of the sabotage attached.

Thoughts on otter proofing fenders? Strap the rope to the dock so fender can't really move?

Hook a 10 lb downrigger ball to the bottom of the fender

You could try filling the fender with water to make it heavy. Or tie the bottom of the fender down so they can't pull it up.

Ammonia with chilli powder spread around the edges of the dock with a cheep princess auto chemical sprayer kept my section of the dock 100% otter free all summer...

Yes ammonia seemed to work well to move them out from under a shed so I could chicken wire all around the shed. I don't think ammonia will last long in the winter rains tho.
