Torquay is £1.30ltr at the moment
Would suggest you get a better nights stay in Brixham marina with B&B's much closer to the boat than Torquay.
Not sure about the price on the Dartmouth fuel barge at the moment although that would also be a better place to spend the night than Torquay!!
Should you need anything if your in this area give me a call, if you have some jerry can's I'll run you to the garage
