I have experienced this at Marthams, though the circumstances were slightly different, Marthams yard staff do all the cleaning and preparation, and as they only have a small fleet and stagger the turnovers they manage well. One trip I was asked to wait while they did an extra deep clean as the previous hirer had had a dog and left wet doggy smells behind, - not a problem, they kept me well informed. the other time it was a case of they had rushed to get the boat launched for my arrival, as I was the first to hire out Jayne 2, Jayne 1 had been taken out of service and they had completely rebuilt the topsides of the spare Jayne hull they had, to get her in service, All I had to do was wait until thy had fitted minor essentials like the front windows, curtain wires, toilet roll holders etc, the catalogue photos were taken just moments before I boardedthe boat went in 2 hours before I took her out, I had a short snagging list on my return, simple things, like a nut falling off the alternator mounting bolt (temporarily replaced with a cable tie by me), but I had communicated the gist of the list to their bridge pilot and when I arrived at the yard the team were waiting ready to leap into action.
on another occasion a cupboard door decided to part company with the strip inside the hinges mounted to, this was once again reported as I came back under potter heigham bridge, upon arrival at the yard, within 10 minutes the door and hinges had been removed and whisked back to the workshops for repair (regluing) a very slick operation indeed.
