Interrupt main and Tatus II 150LP genoa.
Wonderful sail in cooler temperatures. Tacked out of the river and headed for the Bay Bridge. Tried some different traveler and sheet settings on the main. Appeared that at times, I was able to increase our speed from 4.6 knots to 5.0 knots. Keeping 4.6 knots towards the Bay Bridge was easy. Getting that additional 0.4 knots was not. Seemed that about 35* apparent at 10kts, 15 to 20* heel, yields between 4.6 and 5.0kts of boat sheed. Shifting wind out in the Bay. At times, as much as thirty degree header. Wind softened considerably, or so it seemed, for a while on the way back in, then picked up upon reaching Y"AN".
GPX formatted Track . Estimate distance: 9.11nm, estimated average speed: 4.5kts, estimated duration: 2:01
