Bryan and Rick have it way over me in experience and accuracy.
I made the night passage only that one time, and gave the beds a monstrously wide berth. To make my approach, I cleverly followed the bright red light that turns out to be on the North Island Naval Air Station. This, will keep you clear of the beds, but also, I learned the hard way, leads you into the shallows west of Coronado. Having decided it would be good to have had my boat longer than a week before running it aground, being floodlit by military helicopters and boarded by harbor patrol, I opted to hang an inelegant U-turn and go all the way out for another approach. As a matter of dumb luck, my second try turned out to be the proper approach, which takes you surprisingly close to Point Loma.
As we all know, because of the large military presence in SD Bay, it is a fascinating trip all the way down to the South Bay. And if offers a great opportunity to be warned off by almost every branch of the armed services.
