Navoboat is a free, browser-based tool for sketching boat trajectories. Click the chart or type the names of marinas, ports, islands, anchorages, or bays — Navoboat connects them along the water and gives you distance and bearing for each leg.

This is a planning aid, not a certified navigation instrument. Always cross-check against official nautical charts, your chartplotter, and current notices to mariners before getting underway.
