01
Round Adherence
How well scheduled rounds are executed, including physical checkpoint attendance and start punctuality.
Assurance & Risk
Five Assurance Signals. One clear vessel view.
VigiSent is designed to turn detailed onboard activity into a small number of understandable assurance indicators — allowing owners, fleet managers and insurers to identify where performance is strong, where it is changing and where the underlying evidence should be reviewed.
The 5 Assurance Signals
Explain the result instead of hiding behind it.
The proposed VigiSent Index provides a headline assurance indicator. The five signals beneath it explain the operational reasons behind that result and give stakeholders a clear path into the supporting evidence.
02
Round Consistency
How reliably the vessel maintains its expected round programme over time, including missed activity and repeated deviations.
03
Surveillance Gap
The continuity of expected onboard checking and whether periods exist where planned monitoring failed to occur.
04
Hardware Health
The condition of monitored checkpoints and associated assets, including repeat problems and successful resolution.
05
Crew Reliability
How consistently assigned crew execute their rounds, including completion, punctuality and repeated performance patterns.

Safety Score
A simple measure of how well the round was performed.
The current Safety Score measures individual round execution on a 0–100 basis. Up to 70 points come from physically inspecting required checkpoints and up to 30 points from starting on time.
A genuine reported issue still counts as an inspected checkpoint because the crew member physically attended it.
Each whole minute late removes one start-time point.
After 30 or more minutes late, the start-time component reaches zero.
A completely missed round receives a Safety Score of zero.
How the Safety Score works
70 points for attendance. 30 for punctuality.
The formula is intentionally straightforward so the crew, vessel management and risk stakeholders can understand why a round received its score.
Safety Score formula
Checkpoint points = inspected checkpoints ÷ active required checkpoints × 70
Start points = max(0, 30 − whole minutes late)
Safety Score = checkpoint points + start points
Start points = max(0, 30 − whole minutes late)
Safety Score = checkpoint points + start points

VigiSent Index — VI
A proprietary assurance framework.
The proposed VigiSent Index combines the five Assurance Signals into one 0–100 view. The weighting deliberately gives the greatest importance to whether rounds were executed properly and consistently while still accounting for coverage, hardware condition and crew reliability.
The purpose is not to replace the operational evidence underneath. It is to give a fleet manager or insurance user a concise starting point and show them where to investigate next.
Implementation note: the individual Safety Score is part of the current VigiSent product architecture. The broader 5 Assurance Signals and VigiSent Index represent the agreed insurer-facing scoring framework and should be treated as the evolving assurance model until implementation is verified.
Operational coverage
Frequency matters as well as quality.
Two vessels can perform an individual round equally well but still provide materially different levels of assurance if one yacht is physically checked four times each day and the other only once.
The proposed VigiSent Index therefore applies a Round Frequency Factor using the average number of valid completed rounds per day across the rolling 30-day period.
Less than 1 completed round/day× 0.90
1 completed round/day× 0.94
2 completed rounds/day× 0.97
3 completed rounds/day× 0.99
4 or more completed rounds/day× 1.00
Designed for decisions
Start with six numbers. Keep the evidence underneath.
The insurer-facing principle is intentionally simple: do not make a reviewer interpret thousands of scans. Begin with a headline VigiSent Index and five Assurance Signals, then allow drill-down into the rounds, timestamps and exceptions behind them.
For fleet and risk stakeholders
Simple assurance first. Verifiable evidence underneath.
