Practical tools for real passages, bridge clearance, anchor scope, fuel range and more. Built by Pathr on the same marine charts, tides and routing that power the app. No account, no paywall.
Also in the works: Boating Distance Calculator.
Pathr shows this spot live on a nautical chart, the depth under your keel, wind, tide, and live AIS traffic, all in one place.
Love the free tools? Back us as a Founding member.

We build these for the boating community and keep them free, no signup and no ads. If it saved you some time, you can chip in toward the next one.
One-time, secure checkout by Stripe. No account, no subscription. It’s a tip to a small company, so it isn’t a tax-deductible donation. From $25 it becomes a Founding membership instead.
Sending this to one boater who needs it helps us more than a few dollars does.
Got a tool you wish existed, or a change to this one? Tell us and we'll build it.
