I've put my boar there this year - found it absolutely fine & being on the water used her a lot more than having to hitch up, find, slip at right tide, recover, tow back to yard etc.... Freindly staff,& berth-holders, good security.
Only issue has been my berth being on innermost pontoon this year and on drive on dock means can't access at +/- 1 hr low springs
True the parking costs are a bit of a pain, but that would be true in most other S. Devon marinas. You can park right outside for c. 30 min to drop of kit / fuel etc - saves a lot of carrying.
If keeping here on water, not a dock, you will need to anti-foul - lots of marine growth
