Structured field inspection
Tablet-first capture with offline mode. Every checkpoint is typed, every observation is timestamped, every photo is SHA-256 anchored before the clipboard even hits the dock.
New · Phase 1 MVP, inspection-ready One inspection.
One inspection.
Every report your clients need.
SurveyOS is the first field-grade platform purpose-built for marine surveyors, mechanics, and inspectors. Capture once on a tablet — produce mechanic assessments, pre-purchase surveys, and insurance condition reports that hold up in court, at renewal, and in claims.

Two audiences. One platform.
Built for the people who do the work — and the people who trust it.
For Surveyors & Mechanics
Inspect faster. Report better. Never re-type a finding.
For licensed surveyors, independent mechanics, and survey firms who bill for expertise and live or die by the defensibility of their report.
- Tablet-first field capture with offline mode
- Structured findings that compose into multiple report types
- Work-order conversion without re-entry
- Append-only audit trail on every keystroke
A defensible record, delivered in hours — not weeks.
For insurance underwriters, marine lenders, yacht brokerages, marinas, and charter operators who make decisions based on what surveyors report.
- Reports with separated observation / inference / recommendation
- SHA-256-anchored evidence chain on every photo
- Standards-referenced findings (ABYC, NAMS, SAMS, OEM)
- Tamper-evident frozen payloads, version-controlled
The inspection is the asset
Stop doing the work three times.
Every marine professional hits the same wall. You inspect a vessel once, but you write up the same findings three different ways — one version for the mechanic, one for the pre-purchase buyer, one for the insurance underwriter. Each draft risks drift. Each revision buries the evidence. Each format dilutes the work.
SurveyOS treats the inspection itself as the source of truth. Findings are structured. Evidence is anchored. Reports compose automatically from the same captured data — filtered to the scope each audience needs.
Mechanic
Mechanic Assessment
Performance + maintenance focus. All severity tiers. Cosmetic items omitted. Ready for shop use.
Pre-Purchase
Pre-Purchase Survey
Comprehensive for the buyer and lender. Cosmetic items excluded unless tied to value or structure.
Insurance
Insurance Readiness
Filtered to safety, seaworthiness, compliance, and insurance-readiness impacts only. Clean for underwriting.
Core capabilities
Everything a marine professional needs. Nothing that gets in the way.
Defensible findings
Observation, inferred cause, and recommendation stay as three distinct fields — through the UI, the database, and every rendered report. No paragraphs, no confusion, no weak chain of evidence.
Multiple outputs, one inspection
One survey produces a mechanic assessment, a pre-purchase survey, and an insurance condition report — filtered automatically by scope rules. No re-typing.
Work orders without re-entry
Convert selected findings directly into estimate or work-order lines. Every line preserves the source finding ID. Completed work auto-writes to service history.
Audit trail by default
Every state change, every edit, every export is logged append-only at the database level. Your work holds up in court, at renewal, and in claims.
Standards-aware
Attach ABYC, NAMS, SAMS, and OEM references without ever reproducing copyrighted text. Your reports stay clean; the referenced authority stays authoritative.
How it works
Three steps. Every inspection. No shortcuts on the evidence.
1
Inspect
Walk the vessel on a tablet. Every checkpoint, every photo, every measurement captured in the order you want.
2
Findings
Flag issues as you go — severity, impact, photos attached. Observation, cause, and recommendation stay distinct.
3
Report
One click per deliverable. Reports compose from the same inspection, filtered by scope. Freeze, sign, send.
Defensibility by design
Your work shouldn't need a lawyer to explain it.
Observations, inferred causes, and recommendations are stored and rendered as three distinct fields — enforced in the UI, validated at the API layer, and guaranteed by database constraints. Frozen report packages carry SHA-256 content hashes. Every action writes to an append-only audit log. When a claim comes, the record is complete.

Working with SurveyOS
Built alongside the people who use it.
"The inspection I used to type up for four hours after leaving the marina is ready before the client's coffee is cold. The insurance version is on the underwriter's desk the same day."
"We work across Panama, the U.S., and the Caribbean — every jurisdiction wants a different report format from the same inspection. SurveyOS is the first tool that treats that as a first-class problem."
"Between our charter fleet and the vessels we service for partners, a missed finding is an insurance call nobody wants. The audit trail alone is worth the subscription."
"The defensibility of the report is what sold us. When the surveyor separates observation from inference, our underwriting team stops second-guessing and starts binding."
