Features & Capabilities

Sailings is a powerful Chrome extension designed for navigators and sailing enthusiasts to solve common navigation problems involving course, distance, latitude, longitude, and departure. It enables users to plot routes on a Google map between a departure and a destination point using two primary sailing methods: Rhumb line (loxodromic) and Great Circle (orthodromic).

The app calculates courses, distances, waypoints, nodes, and vertices of the Great Circle route, along with the distance saved compared to the Rhumb line. Its intuitive interface allows for adding points via long clicks, choosing different map views (normal, terrain, satellite), zoom controls, and optional GPS location tracking. While it is a valuable navigation calculator, it is not intended for live navigation. Sailings enhances route planning by providing detailed sailing insights directly from your browser.

User Reviews

Users appreciate Sailings as a helpful and easy-to-use offline GPS navigation app for sea travel, especially for short trips. It integrates with Google Maps to aid in waypoint navigation. However, multiple users point out its limited functionality in waypoints handling, as it only calculates direct distance without accounting for land obstacles. Some find the navigation features rudimentary compared to other apps, and occasional issues with responsiveness reduce user satisfaction. Overall, it is useful but has room for improvement in advanced navigation capabilities.

Cons

Limited waypoint functionality; only shows direct distance without considering land obstacles.
Navigation features are basic compared to other apps like Google Maps.
