The founder rate never rises
Not a first-year discount. As long as the subscription stays active, it renews at the founder price while the standard price moves on without you.
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
NMEA 2000 gateway hardware is still in validation. Founding boats are fitted first, and their engine setups shape what gets supported next.
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.
