Yes but take a dozen, moor them to rows of buoys all in one corner of the lake, so all they do is swing in the wind while the sides grow weed and turn green and the occupants ditch their gash over side (oh yes they will). Grasmere is not a river or maritime setting where a trot of moorings is expected. Even in the big lakes, you won's see many trots - as far as I know, there are none in any lake other than Windermere.
In the Broads there is a boating tradition and you can explore in your boat so there was a point to it to make up for the discomfort.
Edited to add: Grasmere is less than a mile long and about 400 yds at its widest. Where are you going to go?
