Maintenance Intelligence for Marine Assets
From signal to service.
Boats do not operate in controlled environments — they operate in salt, heat, humidity, vibration, and real-world human use.
Yet most maintenance programs still rely on static assumptions: engine hours, calendar intervals, and ideal conditions.

SignalNav turns raw vessel signals into Maintenance Intelligence, so operators, technicians, and owners can act before failures happen — not after.
  • Maintenance failures are rarely sudden — wear is cumulative, contextual, and detectable.
  • Engine hours alone don’t tell the story; environment and operational context matter.
  • Data only matters when it leads to better maintenance decisions.

What you get
A practical system for fewer failures and predictable maintenance.

Earlier intervention

Detect conditions that accelerate wear and address issues before they become downtime.

Reality-based planning

Move beyond static hours. Plan service around how the vessel is actually used.

Owner trust

Transparent, defensible maintenance decisions that reduce friction and surprises.

Maintenance Reality Index™ (MRI)
Two boats with 1,000 engine hours do not have the same maintenance reality.
MRI is a dynamic score that reflects how aggressively a vessel’s systems are aging — compared to standard assumptions.
Instead of asking “How many hours since last service?”, SignalNav asks: “How harsh has this vessel’s life actually been?”
