How big is the boat?
There's a couple of routes available from Superior. By motor
vessel it's 7 days from Thunder Bay to Sept. Iles in the Gulf of St. Lawrence following the commercial shipping
channels & locks. By pleasure craft a lot longer using only daylight navigation
You can follow the pleasure craft route
along the north shore of Superior to SS Marie and the North Channel of Georgian Bay to the Trent-Severn waterway. This will bring your out in Lake Ontario
bypassing the commercial shipping
canals. It's a very nice way to go. From there you have two options, cross Lake Ontario
to Oswego and enter the Erie Canal. This will bring you across NY state to enter the Hudson
River. From there it's a straight shot to NY City and the Atlantic. Plenty of jumping off options for an Atlantic crossing
there. The other alternative is to transit the St. Lawrence Seaway to the Gulf of St. Lawrence. That transit will take you a few days to get to Quebec
City. That route
, I believe, will leave you fewer options for a crossing and will likely lead you to a North Atlantic crossing
and fewer options for anchoring/resupply along the way.
The recreational boat canals (Trent-Severn & Erie) offer a beautiful way to travel out of the Great Lakes
. You can purchase
a transit/camping pass from Parks Canada
that'll allow you to tie up at all of their facilities overnight. If you need shorepower you'll have to purchase
that seperately. Many of the sites have washroom & shower
facilities. The Erie Canal offers a lot of free dockage & water/power along the route. As long as you're not in a rush this would be the preferred route out of the lakes. There are a number of Great Lakes
& St. Lawrence River cruising guides
that can help you with anchoring
If you choose the St. Lawrence River route the first part is scenic as you transit the world famous 1000 Islands. Once you pass through those it's pretty boring, mostly commercial ship canal.
It would be a shame to come all the way from SA and miss some of the most beautiful scenery NA has to offer in their recreational boating
canals. If it were me I might consider also doing the Rideau Canal & Ottawa River (if time permitted).
I appologize for the poor quality of the map.
Good luck on your adventure.
