Marine Surveyors on Oahu: Cost & How to Choose
A survey is the cheapest money you will ever spend on a boat in Hawaii. A thousand dollars now versus a $22,000 repower later is not a close call. But the value of a survey depends almost entirely on who you hire — and Hawaii doesn't license surveyors, so the screening is on you.
Here's how to pick one on Oahu, what it should cost, and the questions that flush out the difference between a professional and a guy with a moisture meter.
Nobody licenses marine surveyors — here's what to look for instead
There is no state license for marine surveyors in Hawaii and no federal one either. Anybody can order business cards tomorrow. What fills that gap is voluntary accreditation, and two organizations matter:
- SAMS — the Society of Accredited Marine Surveyors. A surveyor with five years of full- or part-time surveying experience who passes the exam can use AMS (Accredited Marine Surveyor). This is the credential recreational buyers, brokers and underwriters recognize fastest.
- NAMS — the National Association of Marine Surveyors. Requires five years as a full-time surveyor plus an exam to use NAMS-CMS. NAMS roots run deepest in commercial vessels, barges and cargo work.
Plenty of good surveyors hold both. What you want to avoid is the third category: no accreditation, no continuing education, no errors-and-omissions insurance, and a two-page report your lender won't accept. Ask for the credential, then verify it on the organization's own directory rather than taking a logo on a website at face value.
What a survey costs on Oahu
Recreational surveys are almost always quoted per foot of length overall. Published rate cards nationally tend to sit in the $20–$25 per foot range for a standard pre-purchase survey, which puts a 35-footer in the high hundreds and a 50-footer around a thousand dollars or more before extras.
Hawaii tends to price at the upper end of national ranges, for reasons that will not surprise anyone who lives here: a small pool of qualified surveyors, travel time between Ke'ehi, Ala Wai, Kewalo and Hawaii Kai, and inter-island trips billed on top. Rates are set by each surveyor, so treat the numbers below as a planning frame and get written quotes.
| Line item | What it's for |
|---|---|
| Pre-purchase (condition & value) survey | The main event — hull, systems, safety, valuation |
| Short haul or full haul-out | Bottom, running gear, blisters, thru-hulls — billed by the yard |
| Sea trial attendance | Under-load engine behavior, steering, handling |
| Mechanical / engine survey | Separate diesel or outboard tech; oil analysis is extra |
| Rigging inspection (sailboats) | Standing rigging age, terminals, chainplates, furler |
| Travel & inter-island | Common on Oahu; always ask before you book |
Two things people forget to budget: the yard bills the haul separately from the surveyor, and the engine is usually not covered in depth by a general survey. If the boat has diesels or high-hour outboards, a separate mechanical inspection is money well spent — see how many hours is too many.
The three surveys people confuse
Pre-purchase
The most comprehensive one, and the only one a buyer should accept. It covers structural integrity, electrical, propulsion, fuel and other machinery, navigation gear, onboard systems, safety equipment, cosmetics and overall maintenance, with operational testing of systems in and out of the water. It ends in a written report with a recommendation list and a fair market valuation.
Insurance (condition & value)
A narrower inspection focused on whether the boat is a sound risk and what it's worth. Most marine underwriters require one once a boat is roughly 15–20 years old, some as young as 10, and then want it refreshed every three to five years. On Oahu, where a huge share of the fleet is 20-plus years old, assume a survey is a condition of coverage, not an option. Details in boat insurance in Hawaii.
Damage or appraisal
Written after a grounding, storm, fire or claim, or to establish value for a lender, estate or divorce. Not a substitute for a pre-purchase survey.
Questions to ask before you book
- Are you SAMS-accredited or NAMS-certified, and can I verify it in the directory?
- How many boats like mine have you surveyed — same type, same size range?
- Can I see a sample redacted report? (If the answer is no, keep calling.)
- Do you carry errors-and-omissions insurance?
- Is the boat hauled, and who books and pays the yard?
- Do you attend the sea trial, and is that included or extra?
- What's the turnaround on the written report? Days matter when you're on a contingency clock.
- Do you do repair work, or have a financial relationship with the yard or seller?
- Will your report be accepted by my lender and my insurer?
Be there. Seriously.
The single highest-return thing a buyer does is attend the survey. A good surveyor will narrate what they're seeing, show you the soft spot instead of describing it, and tell you off the record which items are deal-breakers and which are Saturday afternoons. You will learn more about your future boat in four hours on the dock than in four weeks of listings.

Salt, sun and the Hawaii-specific findings
Surveys here surface a distinct pattern of problems, because our boats never get a winter off. Year-round warm salt water means marine growth and accelerated galvanic activity; year-round UV cooks canvas, gelcoat, wiring insulation and deck hardware bedding.
- Corrosion everywhere it isn't supposed to be — bonding systems, shaft and rudder hardware, engine mounts, wiring terminals. See what to check first on a used boat.
- Anodes eaten far faster than mainland intervals, and stray current from a neighbor's boat in the same slip row.
- UV damage to canvas, cushions, hatch lenses and gelcoat — cosmetic on paper, expensive in practice. See boat maintenance in Hawaii.
- Bottom growth history — how recently the boat was hauled tells you a lot. See haul-out and bottom paint on Oahu.
Timing it inside your offer
Write the survey into the offer as a contingency with a real deadline, and book the surveyor the day the offer is accepted — not the day the contingency expires. Surveyors here get booked out, and yards need lead time for a haul slot. If you're stacking a survey, a haul and a sea trial into a two-week window, start calling immediately.
Sellers: the same logic runs in reverse. Getting ahead of the findings is the cheapest negotiating position there is — see whether you need a survey to sell and handling survey repair requests.
