This is a summary of how the boat trolleys need to be packed into the shed at the end of each rowing session.
The idea is that if the trolleys are all placed in parallel, they will not rub on the boats on the racks, and it is easy to get the trolleys into and out of the shed with very minimal damage to any of the equipment. Do NOT place them on an angle.
The images below illustrate the sequence to get the trolleys in efficiently.
Start with a single trolley up past the workbench:
Then put the next one to the left, up close to the workbench.
Then follow the sequence below.
To load the river side, it is easy to keep all the trolleys against the river side set of boats.
