Gullsweep. If Seagulls are your problem, we have the solution... The perfect non-harmful bird scarer!
Just about all the boats in the local marina have a Gullsweep (or two) fitted and guess what, Their boats are clean and seagull free!
Each Gullsweep comes complete with a screw-on mount with other mounts available seperately to install Gullsweep on canvas hoods or rails, or if you do not wish to have a screw down mount.
