Great Loop Planning Tools
Great Loop Tools and Planning Worksheets
These tools turn common Great Loop questions into practical numbers and checklists. They are deliberately conservative: the point is not to produce a perfect answer, but to reveal the assumptions that deserve verification before the boat moves.
Start with the tool that matches the decision
Fuel range calculator
Estimate conservative range and reserve before sparse stretches.
Marina vs anchoring estimator
Compare dockage, power, mooring, and anchor nights.
Bridge clearance worksheet
Track air draft assumptions, tide/current margin, and verification steps.
Provisioning checklist
Build a practical reset-stop checklist for groceries, laundry, meds, pets, and spares.
Trip pace planner
Pressure-test days underway, reset days, weather days, and calendar promises.
How to use these tools
Use them before the plan gets emotional. If a tool says the numbers are tight, that does not mean the trip is impossible. It means the crew should call the marina, recheck the chart, add a weather day, measure the boat again, carry more reserve, or choose a calmer staging point.
