Major route forks to research
Canada vs U.S.-only
Canada can be a highlight, but it adds customs/admin, insurance, timing, remote-service, pet paperwork, and air-draft questions.
Erie vs Champlain
Canal status, air draft, locks, scenery, schedule, and Canada plans all shape the right answer.
Okeechobee vs coastal/Big Bend
Depth, locks, weather windows, boat readiness, crew comfort, and insurance limits matter more than route romance.
Marina-heavy vs anchoring-heavy
This affects budget, reservations, dinghy use, power, laundry, pets, social rhythm, and weather flexibility.
Use the decision tree before the crew is stressed
Decision trees are most valuable before a hard choice becomes emotional. If the crew has already been fighting current all day, it is harder to calmly compare anchoring, pushing on, taking a marina, waiting out weather, or changing the segment plan.
Write the route rules while everyone is rested. Decide what triggers a no-go, what creates a call-ahead stop, and what deserves a full lay day. That makes the route feel less arbitrary when conditions change.
Planning checks
- Set thresholds for wind, visibility, current, daylight arrival, and crew fatigue.
- Decide in advance when a marina is worth the cost because it reduces risk.
- Keep a short list of alternate stops for each demanding segment.
- Review the next decision point at dinner, not during the most crowded part of the waterway.
