Auto-Release Clamcleats

1. Test Release load with "cam" at "minimum setting".
2. To increase release load use a screwdriver to rotate cam towards "maximum".

WARNING - To avoid damaging equipment, make small adjustments and test each increase. Tests show that release loads of 240kg (530lbs) are possible with the cam at "maximum" setting.

Smaller or worn ropes release at higher loads than larger or new ropes.

Cam Replacement Kit

• This kit is for anyone who has lost or damaged their original cam or screw.

Be careful with installing this little device. The angle of the line to the device massively impacts the release force required.

In the simple case of the cleat being flat on top of the centreboard, if the line angles up to the cleat the release load is significantly increased, if the line leads down to the cleat, it is significantly reduced.

Also, as they note on the packet, thinner lines -> higher release load.

It all makes sense if you draw out the forces acting on the pivot arm as vectors and resolve them into a force along the pivot arm, and a force perpendicular to the arm.

Trial and error is required, don't simply install and assume it works.
