Pre-Purchase Marine Vessel Condition Intelligence

Inspect Boat Hulls, Seacocks & Engines Before Paying for Haul-Out

Marine surveys cost $500 to $1,500+ and take weeks to book. BoatSurvey Snap scans hull photos, through-hull seacocks, and engine startup audio to map osmosis blisters, dezincification, and bilge leaks in under 60 seconds.

Through-Hull & Seacock Galvanic Corrosion

Differentiates marine bronze, Marelon, and forbidden yellow brass fittings. Detects pink dezincification and green verdigris before valves fail under seawater pressure.

Bonding Wire Continuity Audit
Marine Inboard Engine Bay & Bilge Telemetry
Bilge Telemetry

Engine Bay Fluid Leaks & Motor Mounts

Identifies rainbow oil sheens in bilge water, cooling hose salt encrustations, rusted engine beds, and raw water pump weep hole indicators.
