Commercial vessel operators and marine port engineers face persistent maritime challenges: keeping workboats, tugs, passenger ferries, and offshore support vessels seaworthy and dispatch-ready across dispersed waterways while staying ahead of strict USCG, ISM Code, and classification society requirements. When main engine running hours, auxiliary generator logs, and hull inspection checklists live across paper logbooks and disjointed spreadsheets, shoreside teams lose visibility and vessels face unexpected mechanical breakdowns or port state detentions. Fleet Rabbit delivers specialized commercial vessel maintenance software that combines real-time marine asset tracking, automated running-hour PMS triggers, and USCG/Subchapter M compliant digital inspections into one centralized platform. Minimize unscheduled drydock downtime, streamline planned maintenance schedules, and preserve complete offline vessel records during deep-water voyages with zero shore signal.

Vessel Maintenance Should Guarantee Seaworthiness, Not Cause Port Delays.
Fleet Rabbit unifies engine running-hour PMS alerts, maritime safety management records, and seaworthiness clearance status into one central board built for shipboard crews and shoreside port engineers. Pre-configured templates for propulsion systems, auxiliary gensets, bilge alarms, and lifesaving equipment require zero custom setup.
Why Standard Fleet Tracking Systems Fall Short for Marine Vessel Fleets
Generic fleet maintenance software built for ground vehicles lacks the marine engineering workflows required to handle marine running hours, Subchapter M safety systems, and isolated offshore communication environments.
Running Hours Tracked via Manual Logs
Relying on hand-written bridge and engine room logbooks leads to delayed hours reporting, resulting in missed turbocharger, injector, and lube oil overhaul intervals.
Disconnected Marine Regulatory Audits
USCG Subchapter M, ABS, and ISM Code compliance checks stored across physical binders create severe audit risks and potential port state control detentions during surprise inspections.
Fragmented Deck & Engine Defect History
Work orders, drydock records, and voyage repair requests live across disconnected email threads, making it difficult for port engineers to identify chronic vessel defects.
Offshore Signal Drops Break Log Continuity
Standard cloud-only apps freeze when vessels travel outside cellular range, leaving shipboard engineers unable to log routine PMS tasks, soundings, or safety checks at sea.
How Fleet Rabbit Delivers Commercial Vessel Maintenance for Marine Crews
Fleet Rabbit synchronizes main propulsion telemetry, auxiliary generator running hours, and statutory inspection checklists to ensure vessel maintenance is driven by actual machinery stress. See a live demo focused on commercial marine maintenance.
Running-Hour Marine PMS Alerts
Trigger planned maintenance intervals automatically based on real-time operating hours from main engines, auxiliary gensets, thrusters, and deck machinery.
Seaworthiness & Dispatch Status
Shoreside dispatch and port engineers view real-time seaworthiness badges indicating completed pre-voyage checks, bilge alarms, and active class certifications.
USCG & Subchapter M Digital Audits
Pre-configured safety management checklists covering fire suppression systems, lifesaving equipment, watertight closures, and steering gear tests.
Deep-Water Offline Mode with Auto-Sync
Shipboard engineers log daily rounds, fluid soundings, and repair work orders offline while underway; records automatically synchronize once within port or satellite range.
Closed-Loop Marine Defect Work Orders
Failed inspection items instantly generate categorized repair tickets with photos and engineering notes, routing priority tasks directly to port engineers and port captains.
Role-Based Maritime Dashboards
Shipboard engineers see assigned engine room tasks, captains manage voyage checklists, and shoreside port engineers oversee fleet-wide PMS schedules.

What Marine Port Engineers Say About Fleet Rabbit
Managing planned maintenance and USCG Subchapter M compliance across our tug fleet used to involve endlessly chasing paper binders and spreadsheet logs. Fleet Rabbit gave our port engineers real-time visibility into engine running hours and defect tickets even when our vessels are far offshore, cutting unscheduled downtime and making audit preparation effortless.

Frequently Asked Questions
How does Fleet Rabbit calculate commercial vessel planned maintenance intervals using running hours?
Fleet Rabbit logs running-hour telemetry and daily soundings directly from main propulsion engines, auxiliary generators, gearboxes, and deck winches. Instead of using static calendar dates, the platform automatically triggers service tasks when specific runtime thresholds (such as 250-hour lube filter changes, 1,000-hour injector services, or 5,000-hour top-end overhauls) are reached, ensuring maintenance aligns with actual machinery wear. Book a demo to view the marine PMS configuration board.
Can shipboard engineers and captains log maintenance and daily checklists when deep offshore with no cellular signal?
Yes, the Fleet Rabbit mobile application features an offline-first architecture specifically designed for maritime transit environments without internet connectivity. Shipboard engineers and masters can log daily engine room rounds, complete safety inspections, update hour meters, and attach defect photos completely offline. All recorded data is securely cached locally and automatically syncs to shoreside servers the moment the vessel re-enters cellular, Wi-Fi, or satellite connectivity. Start a free trial to test offline vessel sync.
Does the platform support USCG Subchapter M, ISM Code, and classification society safety management requirements?
Yes, Fleet Rabbit comes pre-configured with standardized maritime safety management templates covering USCG Subchapter M (TSMS), ISM Code, and Class survey requirements. These include pre-voyage seaworthiness checks, steering gear tests, bilge and fire alarm tests, emergency drill logs, and statutory vessel certificate tracking with automated expiration warnings. Book a demo to explore our maritime compliance workflows.
What happens when a shipboard crew flags a critical machinery defect or safety failure during an inspection?
When an engineer or captain records a critical defect—such as an inoperable bilge alarm, fuel line leak, or steering hydraulic pressure drop—Fleet Rabbit immediately marks the vessel as 'Not Dispatch Ready' on shoreside operations boards. This prevents dispatchers from clearing the vessel for transit while instantly generating a prioritized work order with attached photos and defect notes for the port engineer and maintenance crew. Book a demo to review the defect triage workflow.
What is the pricing and contract structure for Fleet Rabbit commercial vessel maintenance software?
Fleet Rabbit is priced at a transparent rate of $5 per vessel per month billed annually, offering full access to running-hour marine PMS tracking, digital Subchapter M logs, offline syncing, and real-time seaworthiness dashboards with no hidden onboarding fees.
