I was tossing up my options with navigation as I have the edge of the Great Barrier Reef which I need to sail around and then just next to it is another small outcropping of reef.  This other outcropping is about 35nm from the Great Barrier Reef.  My initial plan had been to sail directly between the two as this would give me the shortest distance to sail however the wind gods had other ideas making it difficult to make the NW heading that I needed.  At around 11pm last night I was just coming up on that outcropping of reef and needed to make a decision of if I was going to tack and spent the rest of the night tacking between this reef and the Great Barrier Reef or if I just eased sails and changed my heading 10 degrees I would be able to sail right around the outside with no tacking required...
