## What is Sentinel?

Sentinel is designed for the owner of a boat to keep the cost of ownership low while maximizing security and comfort. Sentinel constantly monitors your boat position and vital systems on board, and alerts you of unexpected changes.

This app works in conjunction to the Sentinel Boat Monitor. 

Notice for Hanse Yachts AG boat owners (Hanse, Dehler, Moody, Privilege, Fjord and Sealine): to get started with this app, request your boat's QR code from your dealer!


Ahead of Problems, Always Safe:

Sentinel promptly informs your of an unexpected change to your boat: bilge running too long, battery voltage drop, anchor release and more. 
Safely anchor with the virtual anchor which alerts you when you boat moves unexpectedly
Avoid shallow water with early depth warnings.


Control things remotely:

Let the heater start while you are still on your way to the harbor. Modern boats with digital switching systems can now be controlled remotely and even automated.


Share your experience:

Share your trips with friends, relatives and colleages. Let your boating experience reach those who are not on the boat.
Explore your trips on Nautical charts

### 1/5 — Service partner was incredibly slow

*2025-11-01*

Took over two months for the service partner to register and enable the product - u need a way better program. This is negligence for a brand new boat that I paid a premium price for including this product.

### 5/5 — Aggiornamento in peggioramento

*2023-08-07, version 6.2.0*

Preferivo la versione precedente che permetteva di condividere con maggior facilità la posizione e le navigazioni con gli ospiti e chi restava a casa.

### 1/5 — Assistenza inesistente

*2021-10-20, version 5.0.3*

Quando funziona è valida, il problema è che l’allarme sonoro su iPhone non va , e poi funziona a periodi, cercato di risolvere con chi lo ha installato e tramite Sentinel, ma nulla, si passano la palla uno con l’altro è non funziona.

### 4/5 — Maintenance section

*2020-10-18*

I love the idea of the new maintenance section but every entry seems to appear twice?

### 4/5 — No manuals

*2020-04-06*

With the new update, my manuals disappeared. Update - the problem has since been resolved. It took a couple days but manuals are now back. Overall, the app is a handy tool for monitoring your boat while away. It’s nice to have the manuals available, but a little slow in loading and navigating back and forth. Other than that, I like it.
