Went from Old Windsor to just before Boulters and back again for a little meander, twas a biggun (48 feet) so some locks and Windsor bridge were / was fun! I particularly liked being told to go port side when crew and fenders were starboard (this was half way down the chamber) usually I would have said of course but there was about 1 foot either side of the boat max so it would not have made any difference whatsoever apart from swapping sides half way through the manoeuvre. He was a temp.
Another lock also took its time thats because both sets of sluices were fully open! I wont name and shame but you would not get this at Teddington
