Fred-I don't understand. Accuracy of what bearings? The heading shown on the GPS? Unless you are being thrown all over the place, consider it dead on. If it is holding steady it is as good as anything will get. Current info also tends to be no problem. Read the magnetic heading from the compass, compare to the GPS heading. The difference is current and leeway which AFAIK can simply be treated as one factor. I'd be interested to hear from others if they treat it differently. Rocks are tricky critters, they sneak up on boats without any provocation. Long time ago I had a sudden insight in a J/24 when a couple of us were trying to work from "here" to "there" that there were some few places in between that we weren't supposed to be...one of which seemed awfully similar to where we MIGHT BE. We did a slam 180 and got out of there, then paid a little more attention to the charts. I really don't want to ever see if damage control practices work as well as they are supposed to, I don't trust silicon critters to play without adult supervision. They're too closely related to the ROCKS.
