It happens all the time. You find the boat, agree on a price, and the seller says, “No need for a survey. I had one done last year. Here’s the report.”
It’s free, it’s already done, and it looks thorough. So why pay for your own?
Because that report was never written to protect you. Here’s why, and what an old survey is good for.
It was done for someone else’s needs
Every survey has a client and a purpose. That report was done for the seller, or for whoever was buying, financing, or insuring the boat at the time. Its job was to meet that client’s needs, whether that was an insurance renewal, a lender’s requirement, or a purchase decision.
The purpose decides which survey gets done. Many of the reports sellers hand over are condition and valuation surveys done for insurance. That isn’t a lesser survey than a pre-purchase survey. It’s a different one, built to tell an underwriter whether the boat is insurable and what it’s worth. A pre-purchase survey is built around a buyer’s decision, which is why it includes things like a sea trial and a haul-out.
The findings don’t change, but the relationship does
The client doesn’t change what a surveyor finds. A survey reports the boat’s condition as found, whoever is paying for it. What doesn’t carry over to you is the relationship.
Most survey reports state that they’re for the client’s use. As a buyer, you weren’t the client. You can’t call that surveyor to ask what a finding means, or what they’d want looked at more closely.
It’s a snapshot of the past
A survey describes the boat on the day it was surveyed. A lot can happen since:
- A season of use, or a season of sitting
- A winter, a storm, or a hard grounding
- Repairs, good or bad
- Equipment pulled off the boat before the sale
A survey from 14 months ago tells you what the boat was. You’re buying what it is now.
Your lender and insurer will probably want their own
Lenders and insurers generally want a recent survey, often done within the past year, and many want it prepared for the new owner. A seller’s old report may not satisfy them anyway, and you don’t want to find that out the week before closing.
The seller’s interests aren’t yours
Most sellers are honest. But a seller has every reason to share a clean report and no reason to share a bad one. You don’t know whether there was a second survey, or whether recommended repairs were ever done.
The same goes for surveyor referrals. Plenty of brokers are straight shooters, and a referral can be a good place to start. But you should choose your own surveyor. Ask any surveyor you’re considering whether they have a relationship with the broker or seller.
What an old survey is good for
Don’t throw it away. A previous survey is a useful starting point:
- Give it to your surveyor. It shows what someone else saw, and where to look closer.
- Check the recommendations. Were they fixed? Ask for receipts. Findings from last year that are still open tell you something about how the boat has been maintained.
- Compare values. If the earlier valuation is far from today’s asking price, it’s worth knowing why.
Choosing your own surveyor
- Accreditation. Look for a surveyor accredited by a professional organization such as SAMS® (AMS®) or NAMS (CMS).
- Experience with your kind of boat. A pontoon, a sailboat, and a motor yacht call for different expertise.
- A sample report. Ask to see one, so you know what you’ll get.
- What’s included. Ask about the sea trial, the haul-out, and whether you need a separate engine survey. Haul-out and lift fees are usually paid separately, typically by the buyer.
- Be there. Plan to attend the survey. You’ll learn more about the boat in a few hours than in months of ownership.
Write the survey into your offer
Make your offer “subject to survey and sea trial,” and schedule the survey within the contingency period. That way, if the survey finds problems, you can renegotiate or walk away.
