1. As near as we can tell from the report, six, and possibly
eight planks were removed, all in the area of the three loose planks. From
this, the investigator concludes that it was a localized problem (conclusion
#6). How does he know it's localized when he didn't check other
areas?
2. No indication is given that any effort was made to check any
planks other than the immediate area of the failed planks. Why not? The
obvious answer is that the investigator already had a foregone conclusion
which he set out to prove.
3. A 32 year old wooden boat fastened with steel fasteners would be
a prime suspect to any experienced surveyor. Yet this report would infer
that the rest of the fasteners in the vessel are all okay without any kind
of general survey, and offers no proof of the inference. It justifies not
pulling any planks or fasteners in other areas on the absurd argument that
the nails are too hard to pull. This on a wrecked hull on which the
fasteners could have cut out.
| "134. Generally, all marine surveyors and Coast Guard inspectors
testifying on the feasibility of removing nails for examination felt
removal of a plank was more prudent than individually removing nails,
due to plank damage caused by removing nails." |
4. As any experienced surveyor knows, bay bottom boats bear that
name for good reason. Transverse framing is a shortcut method of boat
building, intended for vessels used in protected waters because they are
not nearly as strong as longitudinally planked boats. Bay bottom boats are
notable for their tendency for wracking which, in turn, produces the
tendency for leakage, which in turn wreaks havoc on fasteners. Nothing
about the method of construction is mentioned in the report. That none of
these considerations are raised gives rise to either questioning of the
investigator's competence, or his intent.
5. Conclusion #4 explains away the faults found in prior CG
inspections that were never addressed: leaking at the starboard chine
forward, deterioration of wood around keel bolts, plus "working/seepage"
at the starboard side of the keel, midlength in the fuel tank compartment.
Couldn't be due to the broken tank saddles could it? ". . . all indicate
that the vessel was not in optimal condition." Optimal condition? What
does that mean? "However, the circumstances were not severe enough to
result in the issuance of requirements or supervisory direction for the
actions beyond the special inspection notes recommended by the
inspectors." In other words, they made notes in the file on these
conditions but otherwise did nothing. One has to wonder just how serious
does it have to be to get their attention? This explanation is entirely
inadequate.
6. The report states that the fuel tank saddle was broken loose
from its frame fasteners and was resting on a plank. It further states
that a wear pattern existed to show that the condition was long standing.
For the reporter to state that this was a secondary consideration is
ludicrous. Nothing in the report suggests that the entire weight of one
end of the fuel tank was not resting on the plank. One could only conclude
that a fuel tank saddle resting on a bottom plank would be a major
contributing cause to that planks coming loose. This statement is clearly
meant to deflect attention away from the fact that the inspectors did not
find this condition in any of the last inspections. Or worse, that they
knew of it and did nothing. Since the insurance survey has not been made
public, we do not know if the insurance surveyor found this problem. Now
consider the following statement:
| "There was no evidence as of the drydock examination in March 1993
that this circumstance had any affect on the integrity of the hull."
|
As with so many other conclusions in this report, this statement is
inserted in the report with no substantiation at all.
Conclusions of the
Investigation
| "1. The proximate cause of the casualty was failure of the
fasteners in the planks A,B, and C in way of the keel. The relatively
severe seaway provided the forces that worked the planks loose,
flooding all compartments . . . " |
Apparently he means that the seas pulled the planks loose but that the
fuel tank sitting on a plank had nothing to do with it.
This conclusion is also notable for the fact that it does not state what
the cause of the fastener failure was. Why does the investigator
fail to state that the cause of the failure was corrosion? Although
conclusion #3 talks about a variety of metals, including through
hull fittings and ground plates, "contributed to the galvanic corrosion."
At this point we have to be wondering how you build a boat without a
variety of metals under water. Since all wood boats have dissimilar metals
underwater, why is this one more adversely affected? No mention of the
vessel's age is made, nor how long steel fasteners are expected to last.
Nor to the general rule of thumb that even bronze fastened boats should be
thoroughly checked after 15 years, yet alone 32 years.
More importantly, it is widely known that bay bottom hulls defy the
principles of strong wooden boat construction, that they are fraught with
problems, which is why only a few builders in the mid-Atlantic coastal
region used the method.
Conclusions #4 & 5 are also noteworthy for their self-serving
statements. This one deals with the observations made by the CG at the
1989 and 1989 CG hull inspections, as previously mentioned, in which
"working/seepage at the starboard side of the keel midlength in the fuel
tank compartment," "leakage around the keel," and wood deterioration
around the keel bolts were observed yet no orders for repair were given.
Isn't this precisely the area where the planks popped loose?
Conclusion #5 is particularly interesting from the standpoint that
it draws the conclusion that the wastage of fasteners at the 3 planks is a
"local problem" and is a conclusion without substantiation. "The location
was subject to abnormal corrosion rates due to being a low point
where bilge water would collect, to the variety of nearby dissimilar
metals and to the design of the vessel in the garboard area." Is having a
low point in the bilge "abnormal"? And then this interesting statement:
"The inline end of the bottom planks is conducive to working that would
allow the joint to become loose and the water to enter the joint." This
statement clearly indicates that the investigator is aware of the wracking
problems with bay bottom boats. He knows that the bottom planks work, and
yet would have us believe that it's strictly a "local" problem.
All by itself, the above paragraph contradicts and invalidates the
entire investigation report. If the inline end of the bottom planks are
conducive to working that would allow water to enter the joints, then it
follows that the nails are going to get wet and corroded. No galvanism is
necessary as salt water does a wonderful job on steel, galvanized or not.
Further, it had been substantiated in this and prior inspections that
there was looseness, working and leaking of water from inside the vessel
when it was hauled. Apparently the effect of looseness and water exposure
to steel nails at that time "were not serious enough to result in issuance
of requirements . . ."
But these conditions are now serious enough to be cited as the cause of
corrosion of the fasteners that ultimately sank the vessel and killed
three innocent people. In just a few years, a period of time when drydock
inspection was postponed three times, it went from not serious to complete
failure. To accept these statements at face value, one would have to
believe that the CG inspectors and the investigator had no knowledge of
the corrosive effects of sea water on galvanized nails. Yet the report
reflects that they do know.
Any objective investigator would have concluded that the CG had failed in
its prior inspections, what with their files containing notes of these
serious conditions, to issue a requirement for mandatory fastener
inspections, along with granting of delays for drydock inspections. After
all, they are not inspecting farm equipment but certifying a public
conveyance that is going to sea in the dead of winter.
Conclusion #10 passes the buck by saying that there is no
"well-known published guidance in the marine industry" on when fasteners
should be inspected. This despite the fact that they are the certifying
authority and it's their responsibility to know, not blame it on the
marine industry. But then the writer destroys his own argument by saying,
"Much of the available guidance on fastener examination typically assumes
indications of wastage are present to suggest examination." This is utter
nonsense: the surveyor does not have to see external evidence of fastener
wastage to know that 32 year old steel nails are likely to be completely
wasted, yet alone moderately so. Of course, no references are ever cited.
Yet the most well known book around, Ian Nicholson's Surveying Small
Craft goes into great detail about inspecting fastenings, including
discussion about telltale evidence that suggests fastener problems.
The Statement of Fact section of the report item #6 notes that CG Vessel
Inspection Circular (NVIC) No. 1-63 recommends against the use of
cut nails due to a lack of holding power in some circumstances. ABYC
Project H-7 recommends against the use of ferrous fasteners, and if
ferrous should be hot dipped galvanized. This does not prevent the
CG from concluding that there is "no published guidance" and no fault of
their own inspectors from following their own recommendations. How
much more guidance do they want? When a privately published and voluntary
standard suggests that it's a problem for pleasure craft, can't
they take the hint that it could be disastrous for a public conveyance
that is 32 years old?
Conclusions 7 & 8 provide cover for the inspectors who carried out
the earlier inspections, explaining why they only examined the "wind and
water line interface, limiting his examination of fasteners to that area."
Obviously they didn't just examine the waterline area because their
"notes" indicate problems at the chine and keel. The essence of this
commentary is that it is the experience of the inspectors that the water
line area is a more critical area to inspect. This is their explanation
for not inspecting the planks at the keel rabbet which this very report
later states is the most probable area to expect corroded fastenings.
Again, the report discredits itself. See Conclusion #5 above.
Conclusion 25 is equally incriminating. I'll reproduce it here in
whole:
| "Although Coast Guard marine inspectors are sensitive to the time,
material and labor costs imposed on owners of wood boats caused by the
requiring the removal of fasteners, there is no evidence that this
sensitivity directly contributed to this casualty. [Emphasis
added] These costs can be considerable for owners of small vessel,
especially those which carry few passengers and have low value. The
impact . . . could drive them out of business . . ." |
How about the cost to the passengers and three people who lost their
lives? Is this a Freudian slip or what? Here the writer is giving the boat
operators a free pass. In other words, because we have passenger vessel
operators who are using old, dilapidated wooden boats to run a public
conveyance, the Coast Guard shouldn't risk bankrupting them by ensuring
that these vessels are safe. As with airlines, if the nature of the
business doesn't produce sufficient revenues to produce safe vessels, then
they shouldn't be in business. As with the ValueJet disaster late last
year, once again we've witnessed a federal regulating agency give a shaky
business operation a free pass on safety. As a result, over 100 people
died.
If ever there was a prime example of how not to write an investigation
report, this is it. These statements are little more than an excuse for
failure to perform, not an objective evaluation. Of course keeping old
boats maintained will bankrupt the owners, just as old jet aircraft can
bankrupt an airline. Why aren't 707's used in passenger service anymore?
That's not an acceptable excuse for allowing defective conveyances to
operate. Old vessels, like old aircraft, need to be retired when their
safety can no longer be assured.
Finally, here is the coup de gras that we would expect from any government
agency investigation of its own handiwork:
| "34. There is no evidence of negligence on the part of any
other government employee or person holding a license or document
issued by the Coast Guard." - emphasis added. |
Of course not. We investigated ourselves and we are
clean! And so are the people we grant licenses to.
