I’ve spent some time since the MC Scow Midwinters reading the North Sails MC Scow Tuning Guide. It’s good. If you haven’t read it recently, you should. Calling it a tuning guide doesn’t do it justice. It’s really a how to sail an MC Scow fast guide.
Among many others, one good point is never to let the deck be in the water. If you do, your heeled too much.
