PredictWind
Raises worth-it and safety for passages; for lake weekends Windy may suffice. Don't let routing complexity become procrastination.
Best for: Sailors and coastal/offshore cruisers.
Skip if: Day trips on protected waters only.

Our take · then cast off
Short editorial verdicts — best for / skip if — not star ratings. When you're done stacking up, Go Today or open My boats.
Windy
Classic boat-days multiplier: clearer go/no-go means more days that feel wise, not reckless. Minimal admin burden. Complements Boat Day Go Today perfectly.
Best for: Essentially every recreational owner.
Skip if: You never leave a sheltered pond with zero wind risk (rare).
TimeZero / TZ iBoat
High worth-it for passagemakers who hate stitching five apps; burden rises for weekend lake boaters. Complements Boat Day for ownership while TZ owns bridge planning.
Best for: Cruisers and Furuno-equipped boats doing serious routing.
Skip if: You're a day-trip recreational owner on one bay.
savvy navvy
Can reduce app-switching for planning days — which raises boat-days lift when go/no-go is clearer. Still verify chart authority for your waters.
Best for: Recreational sailors wanting one planning surface.
Skip if: You already love Navionics + PredictWind and switching costs hurt.
