Have a look at www.biboa.com
Here you will find a great deal of local info related to the Cruise I organise in the area for biboa. This is on the "About" page.
On the "Waypoints" page you will find all the distances and bearings.
Torquay (Torbay, Brixham etc) is about 13 miles away.
PM me direct if you want some more detailed info. I have always wondered about trailer parking with your car at Datmouth. Perhaps you will be able to tell me the answer!
I can recommend an "outside" Italian type place for breakfast/brunch in Dartmouth. It is in the backstreet near where you moor up on the pontoon at "the Russian gun" (not a pub, but a Russian gun!) by the Lower Ferry. The cafe is called something like Quo Vadis or something, can never remember its name-but it's famous locally.
