Continued good progress under grey skies. Will gybe north today, aiming for Chesterfield Reef which is about 120nm NW of us. ETA possibly tomorrow – reef entry is difficult and has to be timed right. The trick is to enter in the morning with the sun high and behind you so that the shallow coral areas are visible. Unfortunately this means there is only a narrow window of opportunity each day, and leaden skies make it even more difficult. We’ll know more tomorrow.
