Condition Survey vs Class Survey: Which Report Does a Bali Buyer Need?

A condition survey is a buyer-advocacy inspection of a vessel’s actual state — structure, systems, defects — used for purchase and insurance decisions. A class survey verifies compliance with a classification society’s rules for commercial certification. A private Bali buyer needs a condition survey; class enters the picture only for commercial charter, larger steel vessels or financing that demands it.

Buyers in Indonesia hear both terms, often from sellers using them interchangeably, and occasionally from a seller waving a class certificate as if it were a clean bill of health. The two documents answer different questions for different audiences. Getting the distinction right saves you either from paying for the wrong report — or from trusting a certificate that never promised what you think it promises.

What Each Survey Actually Examines

Condition survey: the buyer’s document

A pre-purchase condition survey inspects the vessel as she actually is: hull moisture and delamination, machinery condition, rigging age, electrical and safety systems, deck hardware, osmosis, electrolysis, and the long tail of defects that decide real value. The output is a narrative report with findings graded by severity, a valuation opinion, and a recommendations list — written for you, with a duty of care to you. It is the document behind survey-based renegotiation, and in this market it is the single highest-leverage spend a buyer makes; the full scope is described at our independent pre-purchase survey desk for Indonesia.

Class survey: the regulator’s document

A class survey verifies that a vessel meets a classification society’s published rules — structural scantlings, machinery standards, statutory safety items — so the society can issue or maintain certification. In Indonesia this typically means BKI (Biro Klasifikasi Indonesia) for domestic commercial vessels, or an international society for larger tonnage. Class answers one question: does this vessel comply with our rules for its certificated service? It does not opine on cosmetics, liveability, or whether the boat is worth the asking price — and a vessel can be in class while carrying defects a buyer would care deeply about.

When Class Becomes Mandatory

Three situations pull class into an Indonesian purchase:

• Commercial charter operation. Indonesian-flagged vessels in commercial passenger service carry statutory certification, and larger tonnage sits under BKI class. If you are buying a working charter vessel, its class and statutory status transfer questions belong in due diligence — a live issue on every deal that moves through the income-ready charter vessel desk.
• Steel, aluminium and larger hulls. Above roughly 24 metres, or for metal hulls generally, insurers and flag administrations increasingly expect class or class-equivalent standards — including many of the expedition vessels on the dive and expedition vessels for sale.
• Finance and insurance conditions. Lenders and some hull insurers require class maintenance or a class-style special survey as a condition of cover on larger vessels.

Cost, Duration and Output Compared

Indicative Indonesian figures, in USD:

• Condition survey: USD 18–30 per foot; one to two days plus haul-out; narrative report with valuation, usually delivered within a week. Commissioned by and addressed to the buyer.
• Class special survey (renewal): quoted per vessel; commonly USD 3,000–15,000+ for small commercial tonnage once yard time, plate readings and statutory items are counted; spread over days to weeks. Commissioned by the owner, addressed to the society’s rules.
• Intermediate/annual class endorsements: lighter in scope and cost, but still compliance checks — not condition opinions.

The practical takeaway: the two reports are complements, not substitutes. On a commercial vessel purchase you will often need both — class status verified for the operation you are buying, and a condition survey for the price you are paying.

Reading a Seller’s Certificate Correctly

A current class certificate tells you the vessel passed its last rule-compliance check and its statutory items were in order at that date. It says nothing about the port engine’s oil analysis, the saloon’s soft decks, or the rigging’s age. Conversely, a glowing condition report from two owners ago has no standing with BKI or an insurer needing class. Ask for both documents, date-check both, and commission your own condition survey regardless — with a surveyor whose duty runs to you, chosen from the pool we mapped in Indonesia’s independent yacht surveyor landscape.

Frequently Asked Questions

Can a class surveyor do my pre-purchase condition survey?

Sometimes the same individual holds both competencies, and on steel or commercial vessels that dual background is valuable. What matters is the engagement: for a purchase, they must be retained by you, reporting to you, in condition-survey scope — not wearing the society’s hat.

Does a private yacht in Indonesia need class at all?

No. Private pleasure vessels are not required to be classed. They need registration and safety compliance for their flag and use, and insurers will want a recent condition survey — typically every three to five years for cover renewal.

The seller’s boat is “in class” — can I skip the condition survey?

Skipping it would be a mistake. Class attests rule compliance for certificated service, not overall condition or value. Vessels in class routinely carry buyer-relevant defects. Verify the class status and commission your own condition survey.

What happens to class when the vessel is sold?

Class does not automatically follow the new owner. The society must be notified, and change of ownership or flag can trigger an occasional survey before certificates are re-endorsed. Sequence this in the closing timeline if the operation depends on it.
