Tuesday - MWE Weather Analysis

Today's forecast is entirely for light air.

In air under 6 knots the air has a laminar-type flow to it.  At 6 it becomes turbulent.  There is not changeover, it's like a switch.

In light air you always want to sail for pressure.  The differences in wind speed are so great that going 20 degrees the wrong way is worth it if you're going twice as fast.

Look for the puffs and try to 'connect the dots' on your way up the course.  If it's not quite that light, look for the closest path to the next pressure and take it.

You need a lot more twist in your sails in light air because the air is flowing at a different speed at the top of your mast than the bottom.  This is caused by the difference in apparent wind.  The apparent wind up top is much more to windward than the bottom, which is why you need more twist in your sails.

Make sure you're flying your top tell tale and aren't over trimmed in the light air.
