Evidence-backed research and practical field notes for the people operating connected marine fleets.
How recreational vessels come out of service and what the public record says that costs — a synthesis of United States towing-assistance records, Coast Guard casualty statistics, and marine insurance-claims analyses, with every figure cited and the evidence classified as observed, derived, or inferred.
The Coast Guard's draft SIP guidance points to separate inspection-budget scenarios by vessel class, performance, and OCMI judgment.
A proposed six-vessel scallop permit would test whether joined sensor records can move days-at-sea accounting from a VMS line to actual dredge activity.
A 2025 Los Angeles–Long Beach amendment shows how adding forecasts and gusts changes a readiness trigger. This historical comparison is not current navigation guidance.
The 2025 reversal of an archaeological-resources rule left a discovery duty in place while removing two numerical instructions. That is a work-plan problem as well as a legal change.
A drivetrain demonstration, a reported navigation pilot and a feature-led pricing strategy point to different questions for the marine technology buyer.
The published total and the published subtraction disagree. The lower result is a reproducible inference, not an agency correction.
A closed 2025 ocean-observing request shows why a marine vendor should decide what a response buys before assembling ten pages of commercial disclosure.
Matching fields from one transmitter can make a vessel record look corroborated. The identity check needs evidence from outside the broadcast.
Posts draw from public sources verified against their publishers. Quantitative claims are cited or transparently derived, inference is labeled, and every publication states its limitations and references. When evidence is thin, we publish an evidence note instead of padding a report.
