5 Best Self-Adjusting Anchor Buoys

#1 Grippy

Fitted with 2 fully watertight chambers housing electronic and mechanical parts, which prevents possible malfunctions due to the marine environment. Extremely lightweight and compact, it has a 200-mm diameter and weighs as little as 1.2 to 1.5 kg.
The ABR version is fitted with a pioneer technology that blocks the line sliding when GRIPPY exceeds 90° inclination while retrieving the anchor so that the signalling buoy can be recovered from its line without using the boat hook.

The end of the GRIPPY line has to be connected to the anchor crown, and it will automatically unwind when deploying the anchor.
The line self-adjustment lets GRIPPY float on the anchor perpendicular consequently signalling its position. At night, GRIPPY automatically activates its solar-powered night lights (LIGHT, HEAVY and ABR versions).

In case of tangled anchor, it can be tripped by retrieving the buoy rope, whose breaking load exceeds 500 kg in the BASIC and LIGHT versions and 1200 kg in the HEAVY and ABR versions. When retrieving the anchor, GRIPPY will automatically wind its line and will position under the boat bow. It comes with a convenient stanchion support (LIGHT, HEAVY and ABR versions) and a pull-out visual signaller.
