My apologies for causing concern.
I had booked LL and when our row in company was cancelled, I offered the crew a low water row in Chichester harbour, as this is seldom seen by our members. On the spur of the moment I thought SD would be easier to launch and knew we would be back by 2pm as SD was booked. BUT and there is always a but, I forgot to post my actions. Sorry again.
That being said, the crew remarked that seeing all the mud flats we are told to avoid actually sticking out of the water was eye opening.
Therefore when tides, times and elements line up I will offer this row again.
