New Settings for the Mk2 Sail

Brett Beyer has updated our cheat sheet for sailing upwind in choppy water, and the changes are shown in red. It's interesting to note that:
  • there are no changes to how you play the mainsheet in any condition,
  • there are no changes to sailing in 5 knots or less, and
  • the most changes are for setting the outhaul.
Brett can be contacted here. When we give a clinic, we print and laminate this chart so that people can tape it to their Laser. Here's your copy...

    Thanks Doug, super helpful. For the outhaul setting, what does "50%" mean? 50% of what?

    In case anyone wants to compare, here's Brett's guide to the previous edition of the Laser sail, the 3.8 ounce:

      Brett is in China, here are his comments:

      This is a reference from maximum on outhaul to maximum off/depth outhaul. So 50% is half way and considered a little on the flat side, but once you are hiking, you need less drag rather than more power. This is true especially with the MarkII sail.

    One more thing - these are all with an aluminum top section, right? If so, it'd be great to see if/how settings change with a carbon section.

      Brett is in China, here are his comments:

      There is not enough difference in bend/stiffness between the aluminium and carbon top sections to make significant setting changes.

    So light air outhaul setting would be 50% x 3/4 hand span (assumed to be 9"?), or 3 3/8" or 8.5cm, measured from boom to point of maximum sail depth?

    As for light air vang setting: would it be 50% x "very firm vang"? How much beyond sheet tension is "very firm"? 30cm? So does that mean snug the vang at block to block and then add about 15cm in light air?

      More comments from Brett:

      To keep a consistent position of reference, it’s best to use the boom outhaul cleat. From this position to the finger tips touching the sail is the measured depth.

      As for light air vang setting: would it be 50% x "very firm vang"? Yes. How much beyond sheet tension is "very firm"? 30cm? Yes. So does that mean snug the vang at block to block and then add about 15cm in light air? Probably around 10cm is sufficient. This is a good position to place a mark on your vang to remind you never to have less vang than this.

    Thanks Doug, very helpful. For the vang setting in 10-15, how's the extra 20 cm measured? On 15:1 or 12:1? Where exactly?

      More comments from Brett:

      Yes, assumed to be on 15:1 vangs and measured as a distance beyond the cleat.
