Mastering The
Great Loop
A 6,000-mile circumnavigation of the eastern U.S. and Canada. From the Gulf of Mexico to the crystal waters of Georgian Bay.
Recommended Viewing: Official AGLCA Introduction
The Great Loop is the ultimate bucket-list journey for North American boaters. It is a continuous waterway that circles the eastern half of the United States and sweeps straight through the heart of Ontario, Canada.
What Exactly is the Route?
As detailed in the AGLCA masterclass [02:14], the route is not a perfectly perfectly round circle. It utilizes the Atlantic Intracoastal Waterway (ICW), the Great Lakes, the inland rivers of the Midwest, and the Gulf of Mexico.
For Ontario boaters, the Canadian segment is largely considered the crown jewel of the entire journey. As experts point out [05:42], Loopers are required to choose between crossing Lake Ontario to the Oswego Canal, or taking the spectacular northern detour...
The Canadian Route Decision Matrix
When entering Canadian waters, migrating Loopers face a choice of legendary waterways. The decision dictates the next 500 miles of your journey.
- 1The Trent-Severn Waterway
Spanning 240 miles with 44 locks, including the gravity-defying Peterborough Lift Lock. It connects Lake Ontario directly to Georgian Bay.
Constraint: Do not attempt if Draft > 5ft

A UNESCO World Heritage site connecting Kingston to Ottawa. Known for its gorgeous historical towns and hand-operated locks built in the 1830s.
Constraint: Speed limits strictly enforced to prevent wake erosion
View Kingston Entry Ramp → - 3Georgian Bay Crossing
Notoriously beautiful but treacherous. Features 30,000 islands and sudden extreme weather systems. Essential to navigate with physical charts and radar.
Constraint: High risk crossing for < 25ft vessels

Vessel Requirements (The "Goldilocks" Boat)
You cannot just take any boat on the Great Loop. According to the foundational guidelines discussed at [11:05] in the tutorial, your vessel must clear several severe constraints:
Must clear the fixed bridge at Mile 300 on the Chicago Sanitary and Ship Canal.
Anything deeper significantly restricts access to the Trent-Severn and rural ICW anchorages.
The Power of the "Boat Card"
With thousands of vessels traveling the loop, recognizing fellow "Loopers" is a major part of the culture. As noted heavily in community literature [18:30], traditional networking is nearly impossible over roaring twin diesels.
That is why the tradition of exchanging Boat Cards was born. These are essentially business cards for your boat, featuring your VHF call sign, boat photo, and MMSI number so neighbors can hail you directly if their anchor begins to drag in a squall.
