I put this paddle to Red Rock out on the discussion board but thought I'd formally post this to see if anyone might be interested. Red Rock is that tiny little island half way between San Rafael and Richmond next to the bridge. The plan would be to launch from Loch Lomond Marina in San Rafael (into an ebb) and paddle out past the Marin Islands, under the bridge, then to Red Rock. At Red Rock we can have lunch and explore "the cave". On our way back (Flood), we can paddle out to the two brothers and check out the light house before heading back. Tides and currents look reasonable but I'm not sure yet about the weather/wind. I would need to check that again when we got closer. Should have self rescue skills, open bay experience and be dressed for immersion. Straight there and back would be approx. 8.5 miles and if we went out to the two brothers on our way back, it would be just under 10. Significant wind would cancel.
