Aim for one of the dolphins. The tide will be low so the upstream one may be clear of the water. It may also be shallow by the second. This doesn’t matter too much. If you go aground, simply use your dinghy to take a rope across to the dolphin.You will float off as the tide rises. If you do not have a dinghy then just use your quant to nudge you closer as the tide rises until you can moor up properly. Again, take great care with fenders. If you have ones that can be mounted horizontally with a rope at each end it will make the job easier. Take time over the fenders as you will be here for a little while.
