SET THE ANCHOR Set your anchor location in real time as you drop it, or specify it later by entering distance and bearing. Advanced users can also input exact coordinates. DEFINE THE SAFE ZONE Define the allowed swing area as a simple circle around the anchor, or create a more precise zone by setting two different radii at specific angles. MONITOR MOVEMENT Stay on top of every movement with comprehensive real-time data. Review key metrics on the main screen or switch to the map view to see your boat's track — ideal for analyzing whether your anchor is holding or dragging. GET ALERTED WHEN IT MATTERS Monitor position, GPS signal strength, and battery level — and receive alerts the moment any of these fall outside your set thresholds. REMOTE ALERTS Leave your phone on board and stay informed from shore. Receive alarm notifications via Telegram or email. With Telegram, you can also request a live status update at any time. APPLE WATCH Keep distance, bearing, and battery level on your wrist with the Apple Watch companion app — all updated in real time. TRY ANCHOR PRO FOR FREE Core features are always free.

The world’s most recognized database for production sailboat specifications. This is the must-have app for those looking to purchase a sailboat as well as for DIYers, sailmakers, yacht brokers, marinas, riggers, and all other marine professionals. Unlike our website, the app allows access to our database without the need for an internet connection. After downloading, you can experience the full app functionality for the first 2 hours. After that, continue on with the free basic version or subscribe to keep full access. This costs as little as a good coffee (for a yearly subscription, our cheapest option) and supports us adding more useful features and extend the database. The current features include: • Scrollable list containing over 9,200 sailboat models. • Side-by-side sailboat model compare. • Scrollable lists with all designers, builders, and associations. • The scrollable lists have an alphabetic index for quick access. • Each list has a name search bar which updates the list as you type. • Ability to select sailboats, designers, builders, and associations as your favorite. • Toggle button to quickly switch between showing all or only your favorites. • Ability to add your personal remarks for each sailboat model. • Favorites and remarks are shared between all your devices using Apple iCloud. • Refined search by LOA, LWL, Hull type, Keel type, Displacement, Beam, Draft, Rig type, Years Built and all our Ratios. • Ability to sort the refined search results on any of the search parameters. • Settings to personalize displayed units and other features. As you scroll through the sailboat list and look at sailboat and designer details, the corresponding images are downloaded via internet. Once an image has been downloaded it is stored on your device; the maximum storage used is about 500MB.

Verdict

The call

The clearest difference is update cadence: SailboatData at every 4 weeks against Anchor Pro's every 2 months.

On price, rating, ads and in-app purchases there is nothing between them.
