Gull deterent on a mooring

The kite dangles round above deck level as the boat moves, I guess.

My experience with one in SCotland is that the farmer said birds gave the kite a clearance zone after few days, so perhaps the learned response is to a pole as much as an active kite ?


Perhaps worth try with an old fishing pole and a ribbon or similar ? I am all for fun experiments.
 
I have used 'buzz line' with some success.
Drawback is having to set it up and remove everytime.

Another drawback is for those on nearby moorings: the noise of my neighbour's buzzing tape 'sounds' through the hull of my boat and is really irritating when I'm sleeping onboard: it makes me think perhaps I should row over and s**t on their decks instead of the seagulls!
 
I bought a Deck Guard Ultrasonic Seagull Repeller but, unfortunately about 43% of humans can hear the ultrasonics. So I had to stop using it when neighbours in the marina complained. It did seem to keep the gulls off, but they still sh*t when they fly.
 
We have found that no one thing works for long,the bas***ds get used to it, keep changing to different things,fishing line,bunting ,etc .The best thing you can do is make your boat unattractive and hope they find someone else;s boat more inviting.
 
What seems to work down here is to tie some thin fishing lines across the boat. It seems that they have trouble seeing it/working out where it is exactly and so they just avoid the whole area. We actually have such lines along the dock here which seems to keep parked boats clear of **** without any needing any other protection measures.
 
Hawk kites are much used by farmers.

e.g.

I bought one of those to deter rooks and jackdaws from nesting or roosting in the mature trees in my garden. I don't have room to fly one permanently but I only have to let out a couple of metres of line and launch it into the air and they're gone within a couple of seconds. They don't like it at all. I only have to use it when I see the birds in the trees which is very rarely these days.
 
Having spent the summer berthed between 2 raggies on a pontoon with many of those things with sticks, the seagulls have been less of a problem this year. I guess the masts interfere with their flight paths.

So raggies are not all bad, but I guess this scenario won't work for the OP.
 
We found these very effective http://www.birdstop.co.uk/daddi_long_legs.asp. One large one mounted on the wheelhouse roof, a second smaller one on the cabin roof. The units lift off the permanently fixed base, slide into a tube and stowed below when you want to use the boat. Found them very effective against gulls and not overly expensive.
