Great Loop Tool
Marina vs Anchoring Cost Estimator
Marina nights and anchoring nights are both tools. This estimator helps separate the emotional debate from the monthly math.

Decision notes
A lower-cost plan can still be a worse plan if it leaves the crew tired, dirty, under-provisioned, or one repair away from resentment. A higher-cost marina-heavy plan can still be bad if it makes the route rigid and reservation-driven.
Interpreting marina costs
Dockage is only one part of the stop budget. Power, laundry, showers, groceries, restaurants, pumpout, pet fees, package handling, mooring launches, resort fees, and extra nights waiting on weather can move the real monthly number quickly. The point of the estimator is to expose the stop mix before the trip becomes a string of expensive defaults.
A low-marina month is not automatically better. Anchoring more often can save money, but it also adds dinghy trips, battery management, water management, trash planning, and fewer easy reset days. A marina-heavy month can be worth it during heat, repairs, guests, medical needs, or a work-heavy stretch.
Ways to control the monthly number
- Use weekly or monthly dockage only where the route pace makes that discount useful.
- Separate maintenance stops from rest stops so repair delays do not eat the whole comfort budget.
- Reserve high-demand areas early, but keep shoulder-season sections flexible.
- Track the cost per reset, not just the nightly slip rate.
Cost estimator mistakes
The estimator can make dockage look tidy, but real marina spending often arrives through add-ons and timing. Power, laundry, restaurants, package fees, repair delays, and extra nights waiting on weather can matter as much as the advertised nightly rate.
- Track actual total stop cost, not just slip cost.
- Add a weather-delay allowance for expensive regions.
- Check whether quoted rates include power, tax, resort fees, and minimum lengths.
- Do not treat every marina night as optional if the crew needs a reset.
