Pre-purchase yacht survey — what to check before you sign

A structured guide for used-yacht buyers in Scandinavia — hull, rig, engine, electrics and paperwork — aligned with FairHelm survey services and academy guides. Not a substitute for an independent surveyor.

A used yacht in Scandinavia can be excellent value - and an expensive mistake if you skip due diligence. This guide helps you structure a pre-purchase survey conversation with an independent surveyor. It does not replace a qualified marine survey. FairHelm publishes education and survey services, not a guarantee of boat condition.

Short answer: budget a condition survey before you lock money in; brief the surveyor with model-typical issues; sea-trial under sail; renegotiate or walk away on the report - FairHelm is not your broker.

In short

  • When: after serious interest + subject-to-survey terms; before an unrecoverable deposit.
  • Focus: hull/deck, rig, engine/drive, electrics, safety gear, papers.
  • Tools: FairHelm model pages, reports, Market Index - brief, don't replace, the surveyor.
  • Sea trial: enough wind to reef.
  • Us: education + survey services - not brokerage, not a condition guarantee.

When to book a survey

Book a condition survey after you are seriously interested and have agreed subject to survey terms with the seller, but before you transfer a deposit you cannot recover. For high-value or older boats, consider a pre-survey assessment earlier in the process to filter obvious mismatches.

Mindhelm angle, briefly: signing without survey is a boundary failure - money and time committed before the boat's real condition is known. Curiosity about teak grain is fine; skipping moisture readings is not.

Hull, deck and structure (GRP)

  • Osmosis / blistering - moisture meter readings, history of treatment, fairing quality
  • Keel attachment - bolts, grounding history, template checks on popular fin-keel models
  • Deck core - soft spots around chainplates, hatches, winches and stanchion bases
  • Through-hull fittings - age, seacocks, hose clamps, bonding
  • Rudder and steering - play, stock condition, autopilot load

Many FairHelm model pages and survey reports describe typical issues for specific designs - use them to brief your surveyor, not as a substitute for inspection.

Rig and sails

  • Mast step, spreaders, rigging age - replace on calendar and hour limits, not appearance alone
  • Chainplates and toggles - common leak and corrosion points on 1980s-1990s boats
  • Sails - UV damage, stitch fatigue; budget replacements if cruising soon

Engine, drive and systems

  • Engine hours vs age, service records, oil analysis if available
  • Gearbox, shaft seal, prop - leak paths and alignment
  • Fuel and water tanks - contamination, smell, access for cleaning
  • Electrical - panel standards, corrosion, battery bank sizing vs realistic use
  • Heating, toilet, galley - function tests under load where safe

Safety and compliance

  • Life raft, flares, fire extinguishers - expiry dates
  • AIS, VHF, MOB gear - fit for your intended sailing
  • Documentation - CE / recreational craft directive where applicable, VAT evidence, registration

Paperwork and sea trial

  • Cross-check HIN, registration and seller identity
  • Sea trial in enough wind to reef - not only a calm marina motor-out
  • Compare listing claims to Market Index snapshots and model specs on FairHelm - large discrepancies warrant questions, not assumptions

After the survey

Use the survey report to renegotiate or walk away. FairHelm does not broker repairs; your surveyor or yard quotes should drive the decision.
