Surveys & Inspections
Get an unflinching read on exhaust integrity, back-pressure, and class readiness — performed by engineers who design and build for ABS, Lloyd's, DNV, and RINA every day.
What this service includes
Whether you're planning a refit, considering a yacht purchase, preparing for a class survey, or troubleshooting an unexplained complaint, an independent exhaust system survey from D'Angelo Marine gives you an engineer-level read on what's actually happening.
Our inspectors document material condition, weld integrity, insulation, mounting, water-injection performance, and back-pressure — and produce a written report you can take to the yard.
Benefits
- Full visual and instrument inspection
- Back-pressure measurement and reporting
- Material and weld integrity evaluation
- Insulation, mount, and isolation review
- Class-readiness audit for upcoming survey
- Pre-purchase inspection for buyers
- Written report with recommendations and budget guidance

Frequently asked
How long does a survey take?
Vessel-dependent. A focused inspection on a sportfish can be a few hours; a full mega-yacht survey typically takes a day or more.
Will you handle resulting repairs?
Yes — but you're under no obligation. The survey report stands on its own and is yours regardless.
Can you survey vessels outside Florida?
Yes. Our mobile teams travel worldwide for surveys, inspections, and repairs.
