Any route with mast upright ? (12 meter)


Not from Lake Champlain, no. There are several fixed bridges
over both river/canal systems. The air draft clearance is
about 15' (4.6 meter). These waterways are far too narrow &
blocked by hills & forest to sail, anyway. On the plus side,
they go thru lovely scenic country.

The southern route, via the Hudson River, is a bit more
friendly to recreational boaters IMHO.
