StopGull Air is a device designed to deter seagulls and coastal birds from landing on cabin tops, hardtops, booms and Bimini tops. Very easy bayonet-coupling mounting. It can be folded or removed for little stowage room during navigation.StopGull is designed to stand any wind speed. By aligning the flags in the same direction it becomes ‘wind-neutral’ so there is no need to disassemble it.StopGull can be mounted on any flat surface and can be combined with hardware for installation on hand rails, Bimini tops, etc.
