Method for GU uphill with a single boat is touch the cill, gentle tick-over, ground paddle on boat side up, this holds bow against lock wakk..
If boat isn't on the cill / rising board on the gate it WILL blow about If ropes are needed, tie back using a stout centre or back-end line and put the engine ahead - a bit quicker than tickover but not too much. This holds the boat agianst the lock wall and ensures you can get it back if it strays. Really brave souls enter the lock at full chat and have their crew draw a full ground paddle to stop them and help the gate shut - If the timing is wrong, one smites the cill and seriously rattles the hanging-up plates in the cabin Ray Butler Nb Owl Down Shropshire
