Rat stopper for boats

The “NO RATS ON BOARD” rat stopper is an effective and easy-to-install solution to prevent rats from boarding your boat via mooring lines. Also known as a rat guard or rat disc, the stopper consists of two parts that can be placed around the line, connected, and secured in place. Installation is possible at any time – no open line end is required.

It can be mounted on both mooring lines and anchor chains, making it especially practical where no open end is available.

The smart design ensures maximum effectiveness: the inner part is fixed to the line or chain, while the outer ring rotates freely on ball bearings. When a rat tries to climb over it, it loses its grip and cannot get on board.

Whether in a marina, on a mooring buoy, or at anchor – this rat stopper provides reliable protection against unwanted guests.
