In these conditions we are at base, 37 on the loos gauge, 566.67 lbs according to the scale (found a nice picture on amazon here: http://www.amazon.com/Loos-Cableware-Tension-Diameter-Measurement/dp/B0000AXNQH).

We don't adjust diamond tension until we are maxing out the downhaul. It is my understanding these two effectively work together and have similar effects on the sail.

Our spreader rake is a full turn out from stock. By my measurement this is at 55mm, the recommended setting for lighter teams. I will double check before the mast goes up again. I can't say this was slower than at the stock 50mm setting in lighter breeze and we haven't tried it in heavier air.

Reading Tripps and Mike's guide they do suggest a little more mast rotation as the breeze builds than what I have been using, if the water is flat.
