Bird Poop Removal and Resistance!

For a deterrent, I've personally used one of those beach ball looking things with the eye one it (I think West Marine??). But most boats in New England have that spinning deal mounted on the deck (think helicopter).

ROFLMAO. Sorry Nick, but welcome to life on a mooring. Wait till a seagull drops a clam from 50' up onto your windshield. My laughter comes with sympathy though. We've all felt your pain.

Softscub with bleach is good for getting the poop off the deck. As for methods to thwart them, there are as many as there are boats in your harbor. The spinning flags tend to be as good as anything, and fairly easy to set up and stow. But to beat the birds completely, well you won't.

BTW, I'm sure you're talking about sandpipers, not piping plovers. If piping plovers are trying to nest on your boat, well I know you're banned from going near their nesting areas on shore.

Works well, however you will need a few at different locations to be effective.
How big is your boat?

I think you're trying to reinvent the wheel. I'd cruise around the harbor, find which boat has the least poop, and do whatever they're doing.

That's the one I was thinking of. You'll see them everywhere in New England.

Yep, that's the one I was referring to also.

I had a serious problem with Cormorant poops (they are big!)
I hoisted a garden nylon bag to the top of the mast and it help.
you can add some 2 mt. nylon straps to the bag, it adds to the noise and volume of the bag
The noise of the nylon bag in the wind chased them away and will not disterb the neighbors

This would not work well on a mooring, but, I saw a guy using a motion sensor coupled with a sprinkler head on a pier nearby. Seagulls try to land and the sprinkler head shoots a pretty good stream of water in a 360* circle. Seemed to work.
Need power though and good water pressure.

What was posted is the down under version of the Gullsweep. Commonly seen on Sportfish in south florida; no one buys the Ozzie version that I know of. The Gullsweep works great at stopping sea birds from sitting on the bow area or railings.

We use nylon fishing line strung across the two highest points. Depending on your beam you may need 4 or 5 strands. Keeps anything flying away from the boat and you really cant see the line while your on the boat either. we have had 100% effective rate at keeping the birds away.

Google "paintball sentry gun".

You can't use the Australian version UP There, cos it would be upside down, right?

lol... literally thousands of techniques have been tried, especially when the seagrapes are in season- all the boats have some amount of purple birdpoop on them. Fishing line strung does little to nothing unless you put so much that they cannot fly between the strands. The yellow balloons with the big reflecting eye hung by a string and the gullsweep are the two cheap, effective, easy to stow methods which have made the cut. Yes a motion sensor with a squirt gun has been tried but it's a hassle. It is very effective but far to complex if you use your boat often.
