Was wird in einem Ankauf-Gutachten besichtigt und bewertet?

Every used yacht has its history. It is all the more important to know what you are getting into when buying. Because some construction sites can be expensive. Anyone who buys a used yacht is usually not looking for a project for the next few years, but a ship that they can use directly, if possible without first having to repair major maintenance backlogs or even structural damage. I can inspect and evaluate boats and yachts up to 24m for you.

An expert opinion includes an inventory of the general state of maintenance, a list of the existing defects and an overview of the necessary measures and repairs according to priority.

This exact inventory significantly reduces your risk when making a purchase. A purchase report gives you good arguments in the context of the purchase negotiations to take into account any deficiencies in the purchase price negotiations,

Therefore, a purchase report is always worthwhile, especially for larger and high-priced yachts.

For a well-founded assessment, the following points in particular are taken into consideration:

 

- Hull and structural elements (engine foundations, floor walls, frames and stringers, hull

Deck connection

- Machines and generator (depending on how long the engine oil has been in use, an oil analysis may also be available here

meaningful)

- Superstructures and decks

- Rig

Visual inspection of masts and spars for possible cracks (e.g. at attachment points for spreaders, winches, ...)

Terminals on shrouds (corrosion, possibly broken strands in steel cables)

Condition and fortification of Püttingen

- Structure and condition of the electrical system (protection, shore power connection, cabling, lighting, ...)

- Steering and autopilot

- Steering system, visual inspection of hydraulic lines or wire pulls, tightness of pumps and hydraulic cylinders

- Function test of the navigation electronics

- Functional test of the anchor winch, any bow and stern thrusters, other deck hardware such as winches,

  davit / dinghy crane etc.

- Safety equipment, life-saving appliances and fire protection

- Sea valves (freedom of movement and condition)

- underwater hull:

  Rudder (condition and bearing play), propellers, shaft brackets, bow thrusters, hull-keel connection, hull openings,

- Lines for water (sea water and fresh water) and fuel

- Fresh water system, pumps, boiler and watermaker

- sewage system

- tanks

- stabilizers

- air conditioners

​

Another important aspect when inspecting on land is the condition of the hull

- In the case of steel and aluminum hulls, after a visual inspection for possible corrosion damage a measurement of the plating thickness using a modern ultrasonic gauge is carried out, especially in areas that may be impaired.

​

- In the case of GRP hulls, the examination is carried out for any osmosis damage or

delamination damage on sandwich hulls and decks.

One method for determining the presence of material damage is to measure the material moisture

with special inductive measuring devices. This is how you usually recognize excessive

water retention in the material that can and probably sooner or later will lead to osmosis damage to the laminate, but also when there is wet core material in sandwich constructions.

 

 

The sea trials are also part of the full assessment. While certain assessments can only be carried out standing on land, for example the testing of seawater-cooled air conditioning systems, the seawater flushing of toilets, but also the trouble-free operation of the propulsion system (running behavior of the propeller shafts), stabilizers and autopilot as well as the running behavior of the machines (trouble-free operation, thermal abnormalities during operation) only possible in the water or during a test drive.
