seek advice on offshore cruiser
The canal system requires you to remove the mast in Lake Onterio. you motor to Albany and then can sail south down the Hudson.
There is a fee, and a season''s pass is 75.00. The alternative is the St Lawrence Sea way which is quite a bit longer, or trucking the boat. The Hudson River, and NY harbor are wonderful. Marinas: they can help with masts at both ends, and inbetween there are places to stay, shop, fuel and so on. Motor yachts cruise the canal all the time, during the summer and it is quite an extensive system. there is a webb site for it. If you beat me to it, stop in Utica and I will meet you for lunch!
