We bought a boat that was stored at South Shore Marine in Chester, NS. There were several other marinas in that area since it is a hotbed for sailing (no fog in the bay!). I was impressed with South Shore. If you need any work done they are equipped for it and the shop rate was very good as I remember (got the hull of the new/old boat compounded and they did a great job and actually steered us away from an Awlgrip job (which they do) so saved us a bundle. Cruisers also get hauled at Baddeck Marine (think that is the name) in Cape Breton.
Any of these places will be much cheaper than Maine I think - no Hinckley affect.
Enjoy cruising down east. We loved Newfoundland in particular.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
