Frequently asked questions....

How much does a survey cost?

Cost should not be your ONLY concern in picking a surveyor, there are differences in education, experience and abilities between surveyors. Look at their resumes and judge for yourself. What you cannot afford is buying a boat with expensive problems that were not discovered in the survey!

You may find us extremely competitive. Do the research.

Why should I use Marinetech Surveys instead of another surveyor?

Check my qualifications and notice that my claims are documented... not just claims. My experience with boats extends to over 30-years now. You may notice that my education and experience is well rounded and complete.

Beware: careful research may reveal little or no related formal education with some surveyors! Anyone with a hammer can call himself a surveyor! On some, you may notice a list of paid memberships instead of a resume. What does this show? THAT HE PAID HIS MEMBERSHIP DUES! There are also many other 'resumes' consisting of a list of seminars at meetings. I have lots of those but I don't even bother listing them. Look for related education. Some schools are diploma mills, check for national accreditation of the school!

What should I expect and not expect from my Marine Surveyor?

Why is Marinetech not in the prefered list of some insurance companies?

Membership fees are often exchanged to be on preferred lists. Your boat survey needs to be performed by a non-biased surveyor for you to get what you are paying for. Marinetech Surveys never pays for its referrals. Nor do we pay to be on anyone's preferred list.

How well does Marinetech check engines?

While we make no claims of being engine mechanics, engines are checked in a General Marine Survey for visual problems such as leaks, tell-tale rust marks, and other clues. Temperature measurements of different components are taken with a digital pyrometer and compared to typical readings. We can do compression testing and oil analysis to go a step further (see the SURVEY page).

One of the most important checks is the sea trial where we go full throttle and check for top end speed and RPM compairing with researched data.


On large diesels we do recommend that you invest in a seperate Marine Engine Survey.

Some surveyors claim to be engine mechanics (also) complete with engine diagnostic computers. If you do the research you'll see that you can get a factory trained mechanic with the diagnostics to do that for you and wind up with a lower total cost for the survey AND engine diagnostics than the jack of all trades surveyor that does engine diagnostics too! TODAY'S COMPLEX MARINE SYSTEMS REQUIRES A SPECIALIST!


Should we have a compression check done on the motor?

I would abosolutely love to take some extra money from you! But honestly, if we can do max RPM and wide open throttle speed as researched, then in my opinion, we have power (and compression). Is this statement infallible? Of course not. It's just a matter of how much do you want to do (and pay for) in order to have the boat checked out? This is a personal thing and something for you to decide.

However, since outboards rev much higher than inboards, I do recommend compression checks on all outboards over 10 years old. This is more effective in determining engine wear than a computer readout.

To sum it up, it's up to you and what you feel comfortable doing.

If the boat/engine do not perform according to researched data on sea trial, I will be the first to recommend further testing.


How do we check for expensive fuel tank leaks?

Marinetech uses an electronic sniffer that actually checks for trace gas molecules to detect leaks in gasoline, diesel tanks. We also use the same instrument to detect propane gas in the cabin.


How do we check for moisture in the hull or deck core?

Marinetech uses the Electrophysics GRP-33 moisture meter to detect moisture. It is the most popular and reliable moisture meter in the industry.


How do I prepare for a Pre-purchase Marine Survey?

Try to get seller to empty out storage areas and not have things stored on top of compartments the surveyor would want to inspect. Any compartments where access is impeded by stores will not be checked so it is to your advantage to do what you can in having a clean, easy to inspect boat ready for the surveyor.

Try to attend the survey so you can see what the surveyor did and didn't do and to assist in removing stores so that surveyor can have greater access.

Try to have seller there to assist with questions, sea trial, and other things that only the owner would know.


How to prepare for an Insurance Survey?

Try to have all the safety equipment available and ready such as unexpired flares, life preservers, etc. The less safety problems the surveyor finds, the easier it will be for you to get insurance.


I have never bought a boat before with enough value to justify the expense of a survey. How does this all work?

See "How to buy a boat" in the ARTICLES page.


What does Marinetech do in a survey?

See that section in the SURVEY page.


Why are you asked to read "What to expect from a Marine Surveyor" before contacting us?

Terms of Survey spells out exactly what to expect from your Marine Surveyor as well as what not to expect. Understanding of what exactly is a marine survey and what it will do/not do for you is crucial for avoiding problems and misunderstandings.


What geographical areas do we cover?

Long Island and eastern NYC and SW Florida are all covered at the regular survey price in season. Other areas may incur a travel surcharge. Call or email for details.


Up to what size boat do we survey?

Charles Avalos is licensed by the US Coast Guard as Master up to 100 tons. This corresponds up to about a 100-foot vessel.


Why do so many other surveyors not list their prices on their websites?

Good question! You stumped me... I really don't know. Some claim that it depends on the age of boat and location. But wouldn't you, the reader, want to have an idea before wasting your time? Maybe they consider themselves good salesmen and want to tell you prices personally?

We are up front with our prices as with everything else. We may not be the best salesmen but we consider ourselves very knowledgable in Marine Surveying.
