Moisture in Hulls?

Wolfe's Prelim

Captain Udorn's Report




Testing fibreglass hulls for moisture:

example from http://www.dixielandmarine.com/yachts/DLyfaq.html#moist

GRP 33 Marine Moisture Meter

Moisture meters are useful to assess moisture intrusion into cored decks, or in wood cored transoms or stringers. Most people, including many surveyors, do not understand the workings of moisture meters or the constraints necessary to achieve a reliable reading on a boats hull.

Moisture meters for use on fiberglass hulls are essentially radio transmitters/receivers.

The measurement actually being made is dielectric constant or AC conductivity, which is affected by type and thickness of bottom paint, trapped water in the paint, thickness of gel coat, thickness of laminate, resin/glass ratio, as well as absorbed water.

The "Code of Practice for the Measurement and Analysis of the Wetness of FRP Hulls"* specifies the methods necessary.

These include:

1. The hull surface must carefully cleaned.
2. A large number of random 4" x 4" areas of the hull must have paint or other coating removed down to the gel coat.
3. The vessel should be out of the water at least 24 hours.
4. Minimum number of measurements must be = approx. one per sq. meter (3.3 feet) or 50-100 on the average 35-40 foot boat.


Excerpt from Wolfe's complete SURVEY REPORT concerning hulls:

THE HULLS FROM WATERLINE TO DECK WAS SOUNDED / INSPECTED FROM A SMALL BOAT AND THOUGH IT IS NOT "FAIR" IN SOME AREAS IT APPEARS IN GOOD STRUCTURAL CONDITION FOR A BOAT OF THIS AGE. ONE THROUGH WAS REMOVED AND "SOLID" LAMINATE FOUND.





Angel Stalker SURVEY REPORT - Raymond Wolfe

September 15, 2005

After a preliminary search of the vessel by Mr. Raymond Wolfe (registered ships surveyor), the findings are as follows.

The overall condition of the ship is poor. This is due, to a large part, from a general lack of maintenance. One problem has compounded into various other issues, resulting in the major structural and mechanical issues seen at present.

Urgent Issues

1. Ships safety and security

Engines
Generators
Electrics
Bilge systems
Through Hulls (fittings and clamps)


Ships Safety

At present, we find as a result of neglected general maintenance, a number of urgent safety issues.

1. All below the waterline through hulls are in jeopardy of breaching. This will result in the boat taking on a significant amount of water and would likely result in the ship sinking.
2. The port side engine is not operational at present. It requires the replacement of the bearing in the water pump. Other issues may exist with one or both engines.
3. The boat uses AC power to operate both the autopilot and the main steering system. This means, if she loses power you are unable to steer the boat. For basic safety reasons, both generators must be functional prior to the boat going to sea. One of these systems should be powered DC for actual safety.
4. Steering system non functional, needs service (manual at present)
5. Auto pilot steering non functional, needs service
6. At present, there is NO AUTO DC bilge pumps installed in the forward bilges. They are currently holding a significant amount of dirty water. This is causing damage to the hull in addition to posing a significant safety concern.
7. All electronics are substandard. There is a significant danger of fire due to poor / inadequate or inappropriate wiring.
8. All grease fittings must be attended to.
9. All oil in Generators. Motors, Compressor, and auxiliary systems need attending to.
10. Fuel filters have never been changed.
11. Fuel tanks must be drained and cleaned.
12. All safety systems including fire fighting are at present non functional.


Other equipment and maintenance issues

1. Ship needs GPRS (for internet connection)
2. Ships log Book
3. Maintenance Log Book
4. Life rafts
5. Fire fighting system
6. Fire extinguishers

Other issues

1. Staff need weekly English classes
2. Log books have to be maintained and checked
3. Staff need to be trained properly
4. Work targets need to be set and checked
5. Uniforms need to be worn at all times (this includes times when general maintenance is being performed.)
6. We need to hire a hostess for the main boat who is available when Michael his here and for VIP events.




ANGEL STALKER - Capt.Udorn Emminom

September 5, 2005.

TO WHOM IT MAY CONCERN,

I would inform about the state of the boat after I have done in the position of Captain in Angel stalker as below.

1. Structure of the boat for over all is still OK. But some part needs to be repairing or renew for example,
o Guest Cabin leaking port and starboard.
o Toilet room leaking and termite.
o Captain cabin leaking and termite.
o Saloon leaking.
o The wall is rotten and termite
o All floors have to check and service as necessary.
o Frame of door and window corrosion also the rubber seal have to be change
o Some of the glass is broken and dirt.
o Sailing and Its composition have to service all over.

2. Interior have to make a new cover of the cushion, change the
carpet and also the curtain.

3. Cushion on sundeck have to renew or new cover.

4. Boat function.
o Water system is issue very low pressure because the supply pipe is too small.
o All water cock is corrosion.
o Heater tank is rusty.
o Water maker have to be servicing.
o Fuel tank and water tank have to cleaning and servicing.
o Wiring have to make new arrangement as necessary.
o All ventilation has to be servicing.
o Electric supply is complicated, 12V - 24V- 380V- 220V-110V. single phase and three phase, also the Generator is malfunction.
o Bilge pump have to make new arrangement.
o Put new indicator for the fuel and water to the wheel house.
o Steering system has to change to modern system.

5. Accommodation.
o Refrigerator have to change or servicing 4 unit
o Air-condition it should be new arrangement.
o Ice maker have to be servicing and feed purified water to the system.

6. Safety System.
o Life raft has to be servicing.
o Fire fighting system has to be servicing.

7. Engine& Engine room, Engine room is complicated must be make new
arrangement, the engine is very old, rusty, less horse power difficult to find the spare part, also it is very expensive need to be servicing or change.
This note is some part which I have inspected but it is not including all over until we take her to the dry dock and make detail reparing .for the safety of the guest, company property and make business with most efficiency .She must have renovation.

Best regards,
Capt.Udorn Emminom.
