My Helm
A clearer view
from the helm.
A practical companion for coastal boating in New Zealand and United States waters. It shows your GPS position on official reference charts—LINZ in New Zealand, NOAA in the US—with a one-tap man overboard button, Saved Places, spoken proximity alerts and an adjustable Anchor Watch.

Practical tools underway
The essentials together in one view.
Designed for a tablet or phone at the helm, with large controls and clear information that remains easy to use on the water.
Anchor Watch
Set the anchor position and choose an adjustable swing limit for the anchorage.
NZ and US reference charts
LINZ charts for New Zealand waters and NOAA charts for US waters. US charts need no account or key.
Saved Places
Store waypoints, hazards and fishing spots with their own map symbols.
Proximity alerts
Receive spoken alerts near enabled places—even when a category is hidden by a filter.
Offline charts and backup
Save charts for your cruising area to use with no mobile signal, and back up your Saved Places.
Man overboard
One tap marks the spot.
If someone goes over the side, hit the big red MOB button. Helm instantly marks your position on the chart, then shows the distance and bearing back to that spot and the time since they went in—with spoken updates, so you can keep your eyes on the water.
On the chart
Official charts, both sides of the Pacific.
The same app, the same controls—LINZ charts in New Zealand, NOAA charts in the United States.
Built for NZ and US waters
Two chart sources. One app.
My Helm uses official LINZ reference charts in New Zealand and NOAA charts in the United States. GPS, Anchor Watch and Saved Places work anywhere, but detailed charts cover New Zealand and US waters only.
Offline charts: charts normally load over the internet. Before you head out, use Download charts to save the area you cruise so charts still show with no mobile signal. Offline copies don't update themselves, so download them again every few months.

Safe simulated demonstration

The demonstration uses a fictional boat route and sample places on a New Zealand (LINZ) or United States (NOAA) chart. It does not request GPS, send notifications, trigger a real alarm or store your changes.
Important safety information
A companion—not primary navigation.
My Helm is a supplementary reference aid. It is not a substitute for current official charts, a compliant chartplotter, prudent watchkeeping, a dedicated anchor alarm, or your man overboard procedures and safety equipment such as a PLB or EPIRB.
Which waters does My Helm cover?
Detailed charts cover New Zealand (LINZ) and United States (NOAA) waters. GPS, Anchor Watch and Saved Places work elsewhere, but without detailed chart coverage.
Do I need an account or key for the charts?
US charts from NOAA need no account or key. New Zealand charts need a free LINZ Data Service access key, which you enter once in Settings.
Will charts work with no mobile signal?
Yes, for areas you have saved with Download charts. Areas you have not saved need an internet connection.
What does the MOB button need to work?
GPS must be on. Press Start GPS when you leave the dock so Helm is ready to mark the position the moment you press MOB.
Do filters disable alerts?
No. Saved Places filters change which categories are shown on the map and in the list. Enabled proximity alerts remain active for places hidden by a filter.
Is Anchor Watch affected by Saved Places filters?
No. Anchor Watch is an independent safety tool and remains visible and active separately from Saved Places categories.
Does it replace a dedicated anchor alarm?
No. Treat Anchor Watch as a supplementary aid and maintain prudent watchkeeping and appropriate dedicated equipment.
