Dear listees,

What advice do you have regarding a survey on a new boat under
construction.

Does one do an engine survey on a new engine, for instance?

How often and at what stages should the surveyor poke his nose in, do
you think?

Thanks

Simon Kornberg

Hi Simon:

Regarding the new engine. I believe that if it is a major builder of diesels
then you would have to wait for the sea trials prior to accepting the final
delivery of the boat, in regards to the engine. The sea trials should put
the boat thru all of its paces. In a hard but not abusive manner.

Most owners will ahve a Naval architect or a marine engineer vist the yard
to do periodic inspection to make sure they build as speced. If the boat is
to be built to a classification bureau spec like ABS then part of the cost
of the boat is to have these people inspect the boat to make sure it passes
their stringent specs in order to be ABS certified. (ABS - the American
Bureau of Ships  www.eagle.org ) There are also european bureau's  like Det
NorskeVeritas which is the major one in europe

What advice do you have regarding a survey on a new boat under
construction.

you think?

IMHO, it makes a difference whether you are building a production boat or a
"one off" that you have had designed.  We had a surveyor look in on our
Nordic Tug every week at the factory and it was not too often.  It was
amazing how different each boat was and what he was able to catch.  You know
the saying "squeaky wheel gets the grease."  Our surveyor, Matt Harris, was
ultimately responsible for design changes that the factory incorporated in
every hull thereafter.  We felt pretty good about our contribution to the
line (at our expense) until they later called him "the master of the
obvious."  Well, if it was so obvious...(enough said).

In a non- production boat you likely need even more attention.  You need the
naval architect to make sure that the design is being followed and very
likely to "tweak" minor items as you go.  I do not believe that anyone can
draw a perfect design on paper.  Things change as they come to life.  Naval
architects are like all professionals, they have their strengths and
weaknesses.  They may need help in overseeing parts of the construction or
installation of certain systems.

As someone else said in reply, the engine and gear are pretty well looked
after by the manufacturer.  The manufacturer has a strong interest in seeing
that the installation is correct (and prop is pitched right, for example)
because they are on the hook for the warranty.  Sea trials are almost always
included as part of the purchase.  These guys typically really know their
stuff and act as a resource for the naval architect and the builder
throughout the entire process.

When all is said and done you may need a survey for any new boat for
insurance purposes.
