Plan B - we went with the dinghy anyway. It actually wasn’t too bad though we were flying along underwater and had to swim occasionally to avoid the dinghy getting swept onto reefs. We had a nice dive, albeit quite short as the wall wasn’t really a wall - it bottomed off around 15m and got a little boring as we drifted along. We’ll try and find another boat and get a bit further along the outer wall....
