Founding Fleet.
500 seats at half price.

Salinity is not in the app stores yet, so nothing is charged today. A founding seat pays $12.50 a month instead of $25, for as long as the subscription stays active, and includes your first Salinity gateway. Nothing is charged until the app is on your phone and your thirty days aboard are up.

Half price while you stay subscribed

$12.50 a month instead of $25. It renews at that price for as long as the subscription stays active. Cancel and the founder rate ends; it does not come back.

Thirty days aboard, not seven

Salinity learns your boat over whole trips, not hours. A founding seat gets a full boating month to prove it against your own engine before the first payment, instead of the standard week.

First gateway batch

The NMEA 2000 gateway hardware has not been tested on a boat. Founding boats are fitted first, and their engine setups shape what gets supported next. Extra gateways for more boats have a one-time fee, set before launch.

A numbered seat

Five hundred boats, numbered in the order they reserve. Yours is shown the moment you join.

Reserve your seat

The boat questions are optional, but they decide which engines and gateways we support first — so they are worth thirty seconds.

No card is taken on this page and no charge is made today. When Salinity reaches the stores we will email you once to start your thirty days; the founder rate applies only if you choose to continue after it. You can leave the list from any email we send. Prices are in US dollars before applicable tax and renew automatically until canceled. See the Terms of Use, Privacy Policy, and Safety Notice.
