Keep the brown bit on your right.
How much tima have you got for the trip? Can you take a few days to explore, or do you just need to get there?
You could do any or all of Lulworth Cove, Weymouth, Bridport, Lyme Regis, Exmouth, Teignmouth, Babbacombe, Torquay, Brixham, Dartmouth if you want to. Some of them have limited tidal access, but you would only be doing shortish passages between them.
At the other extreme (assuming you have fuel range) you can come past Swanage, keep close in to Portland Bill, then head straight across Lyme Bay to Start Point and Salcombe. As a variation you can take a slightly more northerly course and head for Torquay - this will give you some shelter in a south westerly and opens up your options if you decide not to go all the way to Salcombe in one hit. Access to Torquay is really easy if you're running out of energy, and Dartmouth is a fantastic place to visit by boat.
Whichever route you take, Lyme Bay is not much fun if the weather is bad so plan accordingly.
A copy of Mark Fishwick's "West Country Cruising Companion" is worth buying for anyone heading west, and there's a new edition out this year. Certainly make sure you are familiar with the approach to Salcombe as it's not obvious.
