Not sure I'd make the trip out there in a SE/SSE. But SW is magic. So clean compared to Wello. After all, it's 25km or so since it left land by the time it gets to the southern end of Moreton.
The sandbank that runs off the southern end of Crab Island is magic. The channel (Day's Gutter) is about 200m wide. No doubt there are plenty of bities in there, but I've only seen one juvenile (0.5m) in probably 30 or more visits. It's not like the Rainbow Channel in that regard. The channel isn't that deep (around 5m) and doesn't lead anywhere - not far inside Crab the channel disappears. My boat draws about 40cm and I can't get through at low tide.
SW is the real pick of the breezes, especially since that's not usually much fun elsewhere. Slaloming through and boosting over the mangroves, crystal clear water, heaps of rays on the banks (which you can usually see easily) and for those big jumps when you don't want to land in shallow water, boost off the edge of the bank and land in the channel. One of the nice things about the sand bank is that it rises very slowly. So for most of the tide you can find shallow butter flat water somewhere - high tide it goes under so you get the chop coming over.
The picture is looking WSW from Kooringal (the little village on the southern end of Moreton) across Days Gutter to the sand bar that runs south from Crab Island then across Moreton Bay to Brisbane in the distance.
