I just did 2 club races solo in about 10-12 knots

On the upwind I work the mainsheet about every 5 to 10 seconds. I have a mainsail that is optimized for 150 kg doublehanded sloop sailing, So there is only so much I can do in the way of perfect trim. Meaning there are quite few times I have to let the sheet out a mtr or so. I do really try to see the gusts and steer up and down in advance as to cut down on the sheeting.

When doublehanding we work the mainsheet more often that I do singlehanded.

Under spinnaker I pretty much do significant trimming untill I find the groove and then I try to steer my way down to the marks. This seems to work rather well. Often I only drop of the groove about 3 to 4 times when going from B mark t gate and then I do a little trimming again.
