That's a lot of current in the wrong direction ... I have no experience with currents in general but looking at current maps at l-36.com it looks like crossing the starting line W to E and going for Red Rock through the North end of Alcatraz avoids the strongest currents, then coming back the same way and sailing East side of Treasure Island to round Yerba Buena, going for Blackaller and then the finish line. That almost amounts to doing one side of the triangle twice ... not sure it makes sense ...
