Bird Spikes on Radar Array

We were recently assigned a new berth and now we have a terrible problem with birds perching on our radome. Their droppings make it look like the boat has been abandoned for years even though weíre usually down several times a week. Itís a nonstop fight to keep the boat clean.

Has anyone had success with glueing bird spikes to the top of a radome? I canít see how it could affect the radar but I thought I would ask before proceeding. Itís a Garmin radome mounted on the mizzenmast.

Fair winds and calm seas.

Bird Spikes on Radar Array

I recently put these on the aft end of my bimini because egrets and gulls were perching there and making a mess in the aft end of the cockpit. It worked immediately. I have not needed to add them to my raydome but I have no doubt they would work there.

Now I just need to keep the little grackle type birds off my masthead, spreaders, backstay and the topping lift for my Dutchman system. They drop crap and palm berries faster than I can clean it up.

Re: Bird Spikes on Radar Array

There are predatory bird calls you can set up to play randomly, that do an excellent job of keeping birds away. Try Googling on it. Sorry, don't know the name of it, but have seen it in action. The area was cleared for about 1/3 mi. around the boat that played the calls. My Jim didn't care for the noise, either, but nice not to be cormorant splooped, too.

Re: Bird Spikes on Radar Array

Hang up a dead bird, in the rigging. It'll keep birds away for 1/5 of a mile or so.

Yes..! Used bird spikes on dome to keep cormorants away after they started roosting on dome last year. (What a mess!) I used 3M high bond tape to install. Also did masthead - and Trip wires on spreaders have worked for years too.

Get the plastic ones (we found ours at Tractor Supply). Goop’d ‘em down. Also zip tied some to our spreaders. Much success!!

We use a plastic owl from the hardware store. Stick a broom handle or suchlike inside him and attach to a stanchion. Any breeze makes him look like he's looking around. No muss no fuss.

Re: Bird Spikes on Radar Array

Can you organise 4 mm diameter [1/8th inch] cordage looped around and arranged in a mesh, 100 mm above the radar dome. This will deter bird landings.
You could similarly use netting that is sold to close the gap between stanchions, commonly seen to contain spinnakers when dropped on foredeck.


I have successfully used cordage mesh on the foredeck to prevent arctic terns from nesting while I was on a mooring.

Re: Bird Spikes on Radar Array

Lottsa good ideas here. However, just be pleased you don't get visits from Australian cockatoos. They are like a mess of badly behaved teenage boys. They are extremely raucous and set about pulling anything apart. They really like wind speed and direction sensors or small antennae at the masthead. They swing on them, showing off, and then bend them. But they will have a chat with you though, and sometimes will even dance with you. They usually descend on a marina so they can all have a show off site.
Once sailing across The Gulf of Carpentaria a large albatross (assumed) sat on our pushpit for days on end. Following weather so no poos on the boat.
