When I raced PHRF, we used 2 courses. One permanent course on the south end of Milwaukee Bay and one throw in course in on the North end of the bay. I always liked racing the throw in course better because it made use of the offset. I may also be biased because I ran the fore deck and it made my life easier (no millisecond hoist and gybe for your life jobs). It always made exiting a mark much less risky and uneventful (in a good way) for everyone.
