About Sentinel - your boat, online

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

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.

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
