I was unsure if there would be enough wind at Rhosneigr and as wind was a bit later than forecast and walked across sand at low water so 115l/6.5m as do not like lugging big kit. Nice riding small chop to sandbank, until I grounded out and broke harness line. Walked back across sand to get another one and wind had blown up and sail has poor top end. Admitted I was well overpowered and changed down to 6m. Wind dropped back a bit but 6m was comfortable and had another hour. Nice blast.
