Commercial & Fleet

Running a vessel — or a fleet?

Commercial vessel operations require a Commercial or Fleet plan. One platform replaces weather routing software, charting software, and paper logbooks — consolidating your bridge tools into a single connected system.

Fleet size Per vessel / month Per vessel / year
Single vessel $149 $1788
2 – 4 vessels $99 $1188 per vessel
5 – 9 vessels $85 $1020 per vessel
10 – 24 vessels $75 $900 per vessel
25 – 49 vessels $60 $720 per vessel
50+ vessels — — Custom contract — contact us

Every Fleet plan includes the shore-side management layer:

  • Fleet manager dashboard — live compliance status for every vessel: certificates, drills, planned maintenance, and rest-hour compliance at a glance, with a red/yellow/green light per boat.
  • Deficiency & corrective-action register — findings tracked fleet-wide from open to verified close-out, with evidence, dual sign-off (vessel attests, office verifies), and an immutable audit trail. Exports to the vessel's audit-binder PDF and CSV.
  • Supply requisition workflow — vessels raise requests, the office approves or denies with a reason, and low-stock parts roll up across the fleet.
  • Daily vessel reports — each boat's morning report delivered to the office automatically.
  • Vessel onboarding by invite — add a boat, send the invite, and it's aboard. Every vessel's data stays isolated to that vessel; the office sees status, not private logs.
  • Plus full access to every CHIEFMATE module on every vessel, onboarding support, and priority response.

Fleet plans are billed by invoice — ACH, wire, or check on your normal AP terms. No credit card required. Commercial plans cover professional, for-hire, and offshore vessel operations.

Billing

Pricing questions

How does billing work?

Individual plans are billed monthly or annually (annual saves ~10%) by card through a secure processor — card data goes directly to Stripe, never our servers. Upgrades and downgrades are prorated automatically. Fleet plans are billed by invoice — ACH, wire, or check.

What's the difference between individual and commercial plans?

Individual plans (Watch Officer / Master) are licensed for personal, non-commercial use. If your vessel operates commercially — offshore, for hire, cargo, crew boat, fishing — you need a Commercial or Fleet plan. See the fleet pricing table above.

Is there a free trial?

Not at this time. Plans are billed month-to-month with no long-term commitment — you can run a single month to evaluate the full platform and cancel anytime from your account page. Emergency procedures are always free.

What happens to my data if I cancel?

Your logbooks, voyage plans, and uploaded manuals remain exportable. You own your data.

Do I need the hardware unit?

No. The software runs in any modern browser today, and Watch Officer and Master plans include the downloadable desktop app for Mac and Windows. The hardware unit is an optional, dedicated offline appliance — a complete backup that never depends on ship's power or network.
