## Description

Anchor with confidence. HoldFast watches your boat's GPS all night and sounds a loud alarm the instant it starts to drag — so you can actually sleep.

Anchor with confidence — and actually sleep.

HoldFast keeps a constant GPS watch on your boat and sounds a loud alarm the instant it starts to drag — even with the screen off. The core anchor alarm is free, built by sailors for sailors.

SET IT. FORGET IT. SLEEP.
• Drop anchor — tap your position, or offset to the exact bow location
• Set your swing — adjust the watch radius from 5m to 200m
• Rest easy — HoldFast keeps watch in the background while you sleep

TRUSTED ANCHOR MONITORING — FREE

ROCK-SOLID BACKGROUND TRACKING — An optimized GPS engine stays awake with the screen off. If your boat moves, you'll know.

NO FALSE ALARMS — You set the GPS-signal-loss threshold, from 30 seconds to several minutes. No more 3 AM "ghost" alerts.

PROGRESSIVE ALARMS — A gentle nudge as you near the boundary, then a loud emergency alarm if you've truly broken free. You're warned early, not too late.

NIGHT-VISION DARK MODE — Keeps your cockpit dark and your night vision intact.

HOLDFAST PREMIUM

Unlock the extras when you're ready — choose an annual plan, or pay once for lifetime access.

CUSTOM ALARM ZONES — Draw a shape around rocks, shallows, or moorings instead of a plain circle.

REMOTE WATCH — Share a private live link so family or crew ashore can track your position in real time from any web browser.

GPS TRACK HISTORY — Replay exactly how your boat swung through the night on a colour-coded track.

CUSTOM ALARM TONES — Choose a piercing tone that's guaranteed to wake you.

PRIVATE BY DESIGN

No account to create. No data collection. No internet required for core alarm functions — the watch runs entirely on your device.

Download HoldFast and take the stress out of the anchorage.
