A few pics to share. Familiar scenes to those who know the area but if not it really is SIB heaven and wonderful for families. Everyone we met from the harbour master to the ferry operators, barmen to shop owners were so friendly. Naturally it's a very boat friendly area with the free slips (we paid harbour dues of £2.60 a day for our 3.4m SIB), helpful locals and easy free landing pontoons everywhere.
We stayed at the top of Dittisham and drove the boat down on the Landy roof, dropping it off on the quay by the Ferry Boat Inn each time but we left it overnight on the penultimate day. This was OK but it's a dead end down a steep road and can be a minor nightmare with getting access or blocked in by a queue of other cars.
Did some research while we were there and next time we may just leave it there the week or maybe store it at the park area opposite the higher ferry slip (£8 a day or £38 a week).
Place seems to be a thief's dream with hundreds of small boats with engines and fuel left all over the place each night but chatting to locals there don't seem to be any serious issues.
We went up to Totnes once (saw a seal a long way up river) but mostly pottered around the Dartmouth harbour area and the harbour mouth, up to Blackpool Sands for a superb blast one day - on the way seeing an Orca (or small shark?). Also saw a dolphin right in the harbour. All in all a fantastic place and not really changed much since I was a kid in the late 70's - neither has the 7 hour crawl/drive down there.
