Hi all,

My wife Mary and I are in the San Diego area and own a 42' trawler (made by
Aquarius) which we purchased in Hong Kong.  We lived on the boat in  Hong Kong
and boated around the islands there.  I got a Master and  Engineers licence,
which is required to operate a powered vessel in the  Hong Kong area.  After
about 8 months we shipped "Mo Mun Tai" to LA  and brought it down to San Diego
where currently do a lot of coastal  cruising.

Our plans are to do long range power cruising and are looking for  another
boat with longer range capabilities.  One of the current  trades we are
wrestling with is steel vs fiberglass.

In general I would take Steel over Fiberglass. But, and here is the gotcha.
Steel boats rust from the inside out. It's not that they have to, it's that
prep and coating of the interior is often not adequate. There are several
considerations, here is my take on them.
If the hull was foam spray coated inside from water line to the gunwale and
the coating is well adhered, and sea water has not been allowed to reach
the steel below the foam, in other words the interior steel is well
protected and liable to remain that way, then a steel boat is just about
perfect.

Unfortunately, all of these proper conditions are a rarity to find,
especially in home built rigs and even many commercial yards are not
careful enough with their prep and you then find the boat is in fact
rusting from the inside out. It may be impossible to fix any of these
problems once the hull has been finished inside. After all, the only real
way to clean steel to bare metal is what is known as "bright white" and
this requires sand blasting and you can imagine sand blasting inside a
closed finished hull! Or, can you?

I have real serious doubts about any surface prep on steel that does not
include sand blasting to "bright white", as being adequate. It then needs
about 12-20 mils of paint. Using half as much paint to the level of 6-10
miles is not enough. Once the paint coating starts failing the entire
interior job is in jeopardy. It may be that power wire brushing might be
adequate if the surface is coated with sprayed foam. The object of all this
is that the surface will still be in excellent condition after 20 years.

The other factor after the job is at sea is to keep water, especially sea
water off the interior surfaces. This means gaskets on hatches, renewed at
regular intervals and aggressively treating any area subjected to salt
water with fresh water, cleaning out and treating with a rust inhibitor
like WD-40.

Vince and other members of the group--

What are the features you want in a passagemaker?
