- That boats going upstream below Chesterton keep to the towpath side until they have reached the middle of the Gut, when they cross over to the non-towpath side, taking the inside of Grassy Corner.
- That at the top of the Plough Reach, they cross back to the towpath side (taking the inside of Ditton Corner) and keep to that side all the way up to the Boathouses.
Note that there are notice boards on the banks to mark the crossing places.
