Etchells Rake Development by North Sails

Step 1. Hoist the tape on the Jib Halyard and cleat when it measures 7400mm down to the top of the cuddy at the front of the mast gate

In recent times we have seen a trend back towards adjusting rake for conditions. The basic rule is a longer forestay in light airs to induce weather helm/feel and carry a shorter forestay as the wind increases, this will reduce weather helm. If you wish to experiment with this variable we suggest trying a range from base + 15mm in light and base -10mm in fresh conditions.

So rake is a critical variable in the tuning and performance of an Etchells and for many years the standard has been to work from the mast lower black band. This has always been a concern to us as the height of the black band can vary considerably due to building tolerances. We have always worked on the assumption that your band is positioned as high as possible but know on many masts this is not the case. For example if your band is 20mm lower than maximum, your rake shall set up 20mm longer and vice versa.

Knowing this, Richie Allanson and I took on the challenge to come up with a rake measurement system that is not dependant on the black band. The following excerpt from our latest Etchells tuning guide is the end result and we are pleased to say very reliable across all makes of Etchells. We have check measured the deck height on Pamcraft, Pacesetter, Smidmore, Heritage and Ontario boats which were all consistent in deck plain. Now the only possible variable is the forestay position fore and aft which has a very minimal effect on the rake measure from boat to boat.

Please call Richie or myself if you would like any more information.

Fast sailing,
