Auto Anchor Chain Counter

Accurate, Real-Time Rode Measurement For Safer Anchoring
The Lewmar AA150 Auto Anchor Chain Counter provides clear, instant feedback on the exact length of rode deployed through your windlass—improving anchoring accuracy, safety, and ease of use. Designed to fit any windlass, the AA150 gives sailors full confidence when setting or retrieving anchor, whether using all‑chain or rope/chain combinations.
Clear, Easy-To-Read LCD Display
The bright LCD screen shows rode length at a glance, with adjustable red backlighting for excellent visibility during night operations. A built‑in docking alarm sounds automatically when the anchor approaches the bow roller, helping prevent accidental hull or windlass damage.
Versatile Measurement & System Compatibility
Choose between feet or metres to suit your preferred measurement system. The AA150 is compatible with DC, AC, and hydraulic windlasses, making it a flexible solution for a wide range of vessel types and anchoring setups.
Easy Installation With Plug-And-Play Sensor
Designed for simple, intuitive setup, the AA150 uses a plug‑and‑play AA sensor that works with rope/chain or all‑chain rode systems. The unit mounts in a standard 60 mm (2.36") marine instrument console for straightforward integration into existing helm layouts.
Multi-Station Ready
Install up to two AA150 units for dual‑station control, or combine with Lewmar’s AA560, AA710, or AA300 series for a multi‑control‑point system—ideal for larger vessels or dual‑helm configurations.
