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.
