Well the cruising guide was very specific noting an entry waypoint and a heading through the reef cut. However, we were getting things ready to pass through the cut and overshot the entry mark. Now we should have probably doubled back and shot the heading from the right spot but we thought we could compensate. Fortunately we only draw 30" because we found ourselves weaving our way around coral heads outside of the deep cut in the reef. Not the way you want to go in but the reefs are gorgeous!
