Extending this comment, before motors it was routine to have to wait for favourable winds, especially in harbours and confined waterways. Here's the famous navigator James Cook setting out from London on his second voyage:

"I sailed from Deptford, April 9th, 1772, but got no farther than Woolwich, where I was detained by easterly winds till the 23d, when the ship fell down to Long Reach, and the next day was joined by the Adventure. Here both ships received on board their powder, guns, gunners' stores, and marines."

So the "Resolution" managed about 8km on the day of departure from the London naval dockyard, then remained anchored in the river for 13 days waiting for the wind to change direction, finally managing 16km to the victualling dock.
