The trip down the St Lawrence and through the Maritimes to NYC
(and back to the Lakes) is referred to as The Down East Circle Route.
If you google
that, loads of blogs come up by people who have made the trip.
The second edition of the Down East Circle Route cruising guide is coming out this spring. It is very detailed. It describes anchorages
, towns, fuel
and lots of info about playing the river current
. I would have to say, dont leave home without it. It can be ordered through yachtpilot publishing. their website is: Welcome to Yacht Pilot Cruising Guides
The distance from Kingston, ON to the Bras d'Or lakes is roughly 1000 nm so add a little more for Toronto and from Baddeck to Sydney
. It is possible to stop every night at an anchorage or port. Then, if you need to, you can make longer passages once you are past Tadoussac--at the mouth of the Saguenay River.
In the summer, you should expect to motor
a fair amount on the river. although the winds are prevailing westerly they are often light so not great sailing until the mouth of the St Lawrence and Northumberland str.
When doing the complete loop, the mast
will have to be lowered on the Hudson
River in order to transit the Erie or Champlain Canals. There are yacht clubs and marinas
on the Hudson
with do-it-yourself gin-poles for mast removal
. the cost is only about $50 and same at the other end for re-rigging.
Hope this answers a few questions and sets you in the right direction for gathering data for your proposed cruise
