A course with a starting line so close to an obstruction that boats have to avoid it immediately after starting is just asking for trouble. Race Committee should never set such a course. If RC is compelled to set that course by the Organizing Authority, I don't think I'd race there.
Ummm, I'd say it's good that you didn't start this race here, with these guys...
Sorry to be snarky, but obstructions, even at starts, are routinely encountered situations, paricularly in sheltered waters. I kinda suck but race enough to know with the right experience, obstructions are interesting, strategic race course variables.
