I use light gauge metal seizing wire from the spreader end going up at a slight angle to the mast. They can't land there and it works quite well. Much less poop since I did that.
When I leave the boat on the mooring
for a week or more, I also string a couple hundred feet of light line just above the main & mizzen booms, and a bit of it port 'n stb between shrouds and up to the headstay. It takes some time but better than cleaning
a stinky boat when I get back.
These things have been pretty good but they still like to chow down on my spacious foredeck. And, sometimes they are on the masthead. Osprey busted my DataMarine wind
machine bracket last year. I need to put that spikey thing up there.
Has anyone tried these electrical
gizmos that make some irritating noise
that scares 'em off?
PS- Anyone know how to get that nasty stain off of my sail covers? Nothing I've tried works.
