Simple, effective, floats, cheap and it works! Music to a sailor's heart, so the LineGrabber, if you haven't tried one already, should be a winner for most cruising sailors.
While there are various knots and mechanical devices that can attach an intermediate tie-off point onto a line, often the best solution is the most simple.
LineGrabber detail - .. .
The LineGrabber from Davis Instruments enables owners to make an attachment point to a line without making a knot. It works by cinching tight around a line. The more tension that is applied to the LineGrabber, the more it tightens on the line.
LineGrabber has hundreds of uses. It can be used to take tension off a jammed line, secure a rescue line, add a secure attachment point to a grab rail or stanchion, lead a static line in any direction, grab chains and railings or climb any rope, line or halyard.
In smaller situations it can also can help secure an anchor or create a temporary mooring. In addition, LineGrabber can attach to any kind of harness or pulley.
Made from 6 mm high modulus fiber with a sewn loop at each end, LineGrabber can hold up to 907 kg.
For any size line from 1.27 cm to 2.54 cm in diameter, users loop the LineGrabber twice around and through itself each time. Cinching it tight then creates a strong, secure attachment point. For lines smaller than 1.27 cm in diameter, the LineGrabber can be looped around three times.
To easily adjust and remove, you just loosen it, slide where needed and cinch it tight. Drop it overboard - and it floats.
If your local marine store doesn't stock one, you can purchase one online for about $20 (£11) or refer to the manufacturer at www.davisnet.com
