The Triangle Loop: Is It Worth the Detour?

For Loopers who can clear 17 feet of air draft, the Triangle Loop offers a scenic and culturally enriching alternative to the more traditional Erie–Oswego route. It adds roughly 750 miles to your journey and is best cruised in 3–4 weeks, though many stretch it into a summer-long adventure.

🌍 What Is the Triangle Loop?

Instead of heading west from Waterford via the Erie Canal and Oswego, sail north up the Champlain Canal → Lake Champlain → Richelieu River → Chambly Canal into the St. Lawrence River, then past Montreal → Quebec City → Sorel, and loop back down through the Champlain Canal to Troy.

Along this journey, you’ll enjoy:

• French-Canadian culture, cuisine & bilingual signage

• Iconic urban skylines and UNESCO heritage cities

• Cellar door wineries and lakefront natural beauty

• Rideau Canal & Trent–Severn access (optional captures)

Pro tip: Go clockwise to go downstream in the St. Lawrence and win delightfully quicker passages and smoother fuel use  .

✈️ Air Draft Requirements

• Triangle Loop (via Champlain/St. Lawrence): ≤ 17 ft clearance ().

  Bridges can drop lower during high water—so always confirm charts and clearing  .

• Erie → Oswego (traditional): up to 20 ft clearance.

• Full Erie Canal to Lake Erie: requires ≤ 15 ft clearance (certain western sections even 15’6″) .

✅ Is the Triangle Loop Worth It?

Choose this route if you want:

• Cultural variety – Quebec, Ottawa, Montreal, Lake Champlain

• Scenic Canadian cruising and historic waterways

• Fewer crowds compared to popular Erie segment

Considerations:

• Time commitment: Minimum 3 weeks to do it justice

• International planning: CBP/CBSA clearance, apps (ArriveCAN, CBP ROAM), valid ID, MMSI/FCC license

• Route complexity: More locks (Rideau, Chambly), St. Lawrence currents, bilingual signs

• Clearance concerns: Must stay ≤ 17 ft and plan for occasional height limitations

🛠️ Tips & Prep

1. Confirm your air draft — measure from waterline to highest point including antennas .

2. Check bridge clearances frequently—levels fluctuate, so use Waterway Guide, AC, Navionics.

3. Plan customs—online ArriveCAN and CBP ROAM apps help streamline border clearance.

4. Know your locks—prepare for single-chamber locks (Champlain), fast currents in St. Lawrence, more lock delays.

5. Expect less crowding—while lines still happen, the Triangle often offers quieter anchorages, especially in Canada.

🎯 Final Take

If your boat’s air draft fits, the Triangle Loop is a worthy detour—packed with scenic variety, international flair, and historical intrigue. It adds miles, but rewards with memories many Loopers cherish forever.
