Hi jnr12 and welcome to the forum,

Polpero & Looe are very tidal.
I may have been lucky in Polpero but one of the local fishing boats let me tie up alongside his boat.
Looe has a strong current both ways on the river. The visitor moorings are (as you enter the harbour) on the left hand side between two white marker boards (not the easiest to see) Make sure you have fenders!
If you have transom wheels and you haven't got a dog, it may be easier to land on the beach.
