Free to join. Pay for the watch you need.
Joining a Dock costs nothing — a neighbor who watches but owns no hardware pays $0, and that is the point. When it is your boat, plans buy how closely it is watched while you are away: the bilge dry, the batteries up, the anchor holding, and how far an alarm travels when one of those stops being true.

Questions
Do I need a plan to be someone's dock neighbor?
No. Joining costs nothing, with or without a boat and with or without a single sensor. A plan is something a boat has, not something a person needs — so the neighbor who watches your boat while you're inland never pays to do it.
Is the app really free?
Yes. Dockside costs nothing and does real work: the alarm when the anchor drags — aboard with the app open, and from the cloud with it closed — the word the moment water rises in the bilge, and a look at your boat from anywhere. Paid plans add the theft security zone, the city-water valve that shuts itself off, and remember more. Alarms are never behind the paywall.
What's Voyager?
The top plan, for people who go far: connections to the rest of your gear, every passage kept as something to look back on and export, the widest reach when an alarm matters, and cameras when they land. A few of its features are still being built — those are the starred rows above, and they're included the day they ship. Free during beta like every other plan. See what's coming on the roadmap.
What does "per boat" mean?
Each boat has its own plan. Everyone you share it with inherits that boat's features when they view it — no extra cost per person.
How does the free trial work?
Every boat gets one month of Weekender on us — start it anytime from the app's Account view (one trial per boat). No commitment: it drops back to Dockside if you don't continue.
Can I cancel anytime?
Yes. Manage or cancel your plan anytime from the web account portal. Your boat keeps working on the Dockside tier.
Start free, upgrade when you're away
Set it up on your network for free, then add a hosted plan the day you want eyes on the boat from anywhere.
