GENERAL DESCRIPTION OF VESSEL AND LIMITATIONS OF SURVEY
. has a riveted all-
steel/ iron shell. Builder was
unknown to the undersigned
Surveyor and it is not known bywhom the fitting out was
carried out.
The vessel was inspected by the
undersigned whilst on a hard
stand at Foxes Marina. The
underwater hull was not
pressure cleaned prior to
inspection so my conclusions
are based on the evidence presented by selected and random sample areas scrappedclean for inspection and measurement. Access was available to the majority of the hull
surfaces but access to the bottom plate was impeded by the hard stand blocks under
the forward and aft and amidships underwater sections. Weather at the time was fine
and dry.
Within this report principal repair recommendations are graded for your information
according to priority as follows:
Urgent Recommendation: must be done urgently, preferably before re-floating and
certainly before any use is made of the vessel.
Recommendation:should be done at the earlier of next docking or within six monthsor such other time scale as may be specified.
Suggestion / advisory comment: for information and consideration, or may be
necessary to comply with BSS waterways standards or regulations on inland
waterways, but not of particular significance to safety or insurability at this stage.
The use of the word appears/appearedindicates that a very close inspection of that
component/system/area was not possible due to constraints imposed upon the surveyor
(e.g. no power available, inability to remove panels).
The use of the word serviceable/adequate indicates that particular system, component
or item is sufficient for a specific requirement.The use of the word good condition indicates that the component /system is nearly
new with only minor cosmetic or structural discrepancies noted.
The use of the word fairindicates that the component/system is functional as is with
minor repairs and should be monitored often to see if its condition deteriorates.
The use of the word poorindicates that the component/system is unsuitable as is and
will need to be replaced or repaired for it to be considered functional.
Readily accessible means cable of being reached for operation, inspection or
maintenance without removal of any craft structure or use of any tools or removal of
any item.
Your attention is drawn to the terms and conditions of survey which were forwardedto you with the survey contract. Parts of the vessels structure and installations which

were found covered, unexposed or inaccessible except by the removal of normally
portable traps and panels have not
been inspected. No dismantling
has been carried out entirely
visually. Electrical, electronic, gas,
plumbing, pumping, fire fightingand alarm systems have not been
tested or inspected as part of this
hull survey.
The vessel was not tested for
transverse or longitudinal
metacentric stability or buoyancy.
It was not possible to ascertain the
maximum allowable load for the vessel.
THE HULL / GENERAL DESCRIPTION
The hull is of fairly standard form with flat bottom and rounded slab sides. Original
plating thickness was estimated on the basis of control measurements taken at points
where deterioration is unlikely to have occurred and was thought to have been
nominally 6mm for the sides and 6mm for the bottom, a perfectly adequate
specification but not equivalent in durability to the heavier standards more common
now. Forward and aft entry and exit lines are reasonable. Fabrication was to a
satisfactory standard as apparent externally.
70 % of the internal plating and framing could not be inspected due to the presence of
lining and I cannot confirm that these areas are free from defect.
TOPSIDES
The topsides remain in satisfactory condition although there is quite heavy general
denting at the port side amidships sections and other areas commensurate with a vessel
of this type. There is some wear to the rubbing bands and some corrosion is developing
generally. These conditions are cosmetic importance only at present. Seams remainsound as far as visible and whilst the stem post shows numerous impact scuffs
condition remains satisfactory.
IMMERSED PLATING
Underwater plating was visually inspected where scrapped clean, by general hammer
soundings and by ultrasonic point residual thickness measurements taken at selected
and random points. Ultrasonic measurements are taken over planes and therefore
represent the maximum thickness of the plating at that point, with a deduction allowed
in respect of the depth of any pitting present. In evaluating the overall condition of theplatting the pitting depth found is taken into account but thickness readings are

recorded over planes with a deduction to be allowed in respect of estimated pitting
depth. These thickness recordings are strictly the point thickness and there is no
warranty that adjoining areas of plating share the same thickness reading.
The bottom has been plated using 6mm steel/ iron over a full length of about
6extending forward from a point at the skeg to a point of a similar distance from thestem and riveted. A satisfactory line of rivets were visible along the majority of the
centre line frames and seams. Newer 6mm steel/ iron over plating had been weld fitted
as repairs at the chine at approximately 12 width at full water line length. The repairs
appear satisfactory, are painted and are free from excessive corrosion.
The waterline plating shows quite heavy general corrosion and pitting to a nominal
depth of about 2mm on both the port and starboard sides. Hammer soundings revealed
no areas of severe thinning but areas of particularly heavy pitting were noted amidships
at waterline level on the port side. Removal of the heavy paint build up in some areas
may reveal further areas of heavy pitting.
Point ultrasonic measurements taken on the bottom plate along the chines and at the
centreline at those points where access was available indicating a remaining residual
thickness over planes generally in excess of 5mm, but with some pitting evident,
although the bottom plating condition is considered to remain satisfactory at present.
The immersed sides returned satisfactory thickness indications over planes in general in
excess of 5.2mm to 5.5mm. Thickness measurements down to 4.5mm were however
recorded at several points amidships close to rivet deterioration, with suggestive of
internal corrosion below the fuel
and sewage holding tankamidships.
13 in number frame rivets (see
image)>were noticeably degraded,
found 24ft feet from the stern over
an 11ft underbody section
amidships and showing signs of
significant metal corrosion.No
evidence of any grounding
damage to the underlying hullareas was evident. Water seepage
from internal bilge areas was
noted through the degraded and corroded rivets, with approximately 2 of pooling sea
water noted in the interior bilge amidships. The 13 rivets were chalk marked for
labelling by the Surveyor. It should be noted at this point that the remaining frame
rivets and parts of the vessels structure and installation which were found covered with
bitumen paint unexposed or inaccessible have not been inspected.
As far as evident underbody plating amidships below the sewage and fuel tanks is
adequate at present but further corrosion could introduce a need for further plating
repairs and obvious plug welds and rivet replacement repairs are recommended in the13 in number degraded rivet fastenings as chalk marked. Efforts should be made to

inhibit the internal corrosion that appears to be occurring in and below / around the
fuel and sewage holding tanks and nearby adjoining compartments.
A 6mm patch plate has been fitted on the starboard side amidships area of the
underbody section. The plate appeared satisfactory to external inspection only.
The counter and keel bottom plate aft is from 6mm stock and remains in satisfactory
condition.
The hull is fitted with a partial watertight bulkhead at the forward end of the cockpit
well. This area was not accessible for inspection from either side without the removal
of stores and or internal lings. The hull is also fitted with a partial bulkhead at the
forward end of the galley cabin, in sound condition as visible.
The skeg and small keel section is in satisfactory condition and was measured at one
point on each face; a satisfactory average minimum thickness over was indicated.
CATHODIC PROTECTION
The vessel was fitted with two hull
zinc sacrificial anodes, and two
stabiliser anodes. All units show an
even erosion pattern and retain
satisfactory mass to provide ongoing
protection for a reasonable period.
(stabiliser angles appeared to bedifferent but this had no obvious
consequence).
SKIN FITTINGS
The above and below waterline through hull fittings consist off welded iron/steel skin
fittings which were hammer and scrape tested and found to be in a good condition. The
seacocks were not inspected as part of this examination. Although it was not possible
to survey all the associated pipework in detail such as I was able to inspect appeared
satisfactory.
The topsides and transom were fitted with a number of fixed welded skin fittings, all of
which appeared to be sound where examined externally and were considered to be a
reasonable height above the water line.
STERNGEAR
The stern gear was examined externally-without opening up-and was found in a good/
serviceable condition overall. The propeller showed no sign of significant corrosion
and the propeller blades were individually sighted for obvious signs of deformation andnone were found. It was not possible to check the condition of the key and keyway,

although the propeller was a snug fit to its shaft and properly secured with a locking
nut and steel split pin. When the shaft was rotated by hand it was free. The stern gland
appeared to be secure and free of defects. It is not known when it was last repacked.
The stern tube and cutlass bearing were secured and in a good condition with no sign
of corrosion or dezincification to the metal. The propeller shaft was not drawn for
inspection nor the tail ends examined. However no signs of surface flaking, fatigue orfretting corrosion to the shaft could be seen.
RUDDER
The rudder which was inspected ashore, was found to be in a serviceable condition.
The hangings were found good without undue wear in either the pintles or the
gudgeons.
HULL PLATING CONDITION CONCLUSIONS
Urgent Recommendations
On the basis of the access available and in the condition as presented for survey
.. hull appears to remain in adequate condition at present, but clearly
significant corrosion of a good number of rivet fastenings has caused some general
depletion and noticeable water ingress on the interior and some internal corrosion is on
going. The 5mm nominal hull thickness in these areas have relatively little margin left
for further corrosion depletion to be acceptable. The internal corrosion to the frame
rivet fastenings below the fuel tanks and sewage holding tank areas will be hard toretain in a thorough fashion. Options such as pumping out the salt water and soaking
with Waxoyl or a thin rust inhibiting oil compound is feasible in the short term,
however in due course removal of the internal fittings such as fuel tanks and sewage
tanks for an in-depth inspection, and repair of the frame rivets, frames and adjoining
plating will undoubtedly become necessary. For these reasons the work should be
carried out sooner rather than later and before re-floating and certainly before any use
is made of the vessel.
Access was available to the majority of the hull surfaces but access to the bottom plate
was impeded by the hard stand blocks and this should not be overlooked when repairsand further investigation is instructed.
Note: When carrying out any welding repairs to this boat care should be taken
regarding insulating board, stores or polystyrene insulation on the interior.
I feel that the vessel is of a type and quality such that the necessary investment in
further anticorrosive hull and rivet repairs is likely to prove a reasonable and viable
long term course. I look forward to being of assistance should you require clarification
of any of the points contained in this report. (images for information attached
