A professional marine survey is your single best investment in the buying process. Here's what a thorough survey covers, how long it takes, and what red flags can affect your negotiations.
Types of Marine Surveys
A pre-purchase survey is the most comprehensive — it covers the hull, deck hardware, structural integrity, all systems, engine(s), electronics, and safety equipment. An insurance survey focuses on the vessel's current condition and replacement value. A damage survey documents specific damage for insurance claims or legal proceedings.
What the Surveyor Examines
- Hull integrity: osmotic blistering, delamination, impact damage
- Deck hardware: stanchions, cleats, chainplates
- All through-hull fittings and seacocks
- Electrical systems: wiring age, bilge pump operation, shore power
- Engine condition and performance during the sea trial
- Safety equipment: flares, life raft certification, EPIRB registration
Using the Report in Negotiations
Every survey uncovers something. A professional report gives you documented leverage to renegotiate the purchase price or require repairs before completion. Don't be alarmed — some findings are expected on any pre-owned vessel.
