Yacht are boats mainly for pleasure,
cruising, racing, in marinas, inland waterways, near
harbor limits. The yachts are constructed mainly of
GRP i.e. glass reinforced plastic or FRP fiber reinforced
plastic. The bigger yachts are constructed of Aluminum.
The size of the yachts varies from approximately 30
feet to approximately 140 feet.
• Yacht is an epitome of luxury. The interiors are usually well appointed.
• The yacht inspection consists of the following.
1) Inspection of the hull
Part of the hull is above water line and part of the hull below water line. On GRP yachts the moisture meter is used on the gel coating to detect the presence of moisture between layers. Bigger yachts which are of Aluminum construction is confined to visual inspection only. Also, review of the documents related to painting.
An out of water inspection of the yacht is required to carry out the above. Besides the hull has hull fittings, penetrations, and ports.
The hull fittings are the propeller, rudder, trim tabs, stabilizer, propeller shaft, bow thruster, stern thruster, etc.
Ports or openings are sea water pumps inlet/outlet, Main engine cooling water inlet/outlet, A/C cooling water inlet/outlet, etc.
On Aluminum hull boats there are Zinc anodes fitted all around the underwater hull. They are checked for wastage.
A visual inspection is done to check everything is proper and in place.
2) Inspection of its interiors
The interiors consist of accommodation which is normally air conditioned. It will have an attached washroom. Bigger yachts have proper bathing facilities. Smaller yachts have only one room as accommodation whereas bigger yachts have a series of rooms all with attached washrooms. The smaller yachts have a music system, television, portable refrigerator, all attached to the accommodation whereas the big yachts have a proper sized kitchen with all amenities like baking oven, microwave oven, induction burners, refrigerators, water coolers, wash basins etc.
Most of the yachts have a sundeck with cushions
Bigger yachts have a carpeted lounge with a big TV and a music system with strategically positioned speakers. All rooms are centrally air conditioned.
We do a check of all furniture, upholstery, fittings, lights whether they as per original plan. A brief check on the appliances whether they are functional.
On the deck of the yacht we do a check with the moisture meter to detect the presence of moisture between the layers of coating.
3) Inspection of the Engine room
Inspection of the engine room comprises of yachts main engines usually two in number. If there is no sea trial the engines are run at idle RPM for about 15 minutes.
Yachts generators are started and kept on idling mode for about 15 minutes.

Condition of the ship’s batteries.
4) Sea trial
A sea trial is conducted for approximately two hours out of which one hour is devoted to run the main engines at the max ,possible RPM continuously for one hour if circumstances permit .If the sea trial is inside the Marina then running at maximum engine RPM is limited.
Following parameters are noted during sea trial. Engine noise and vibration. Engine lube oil temperature and pressures. Engine cooling water temperatures and pressures. Engine RPM.
Yacht speed in knots. Maneuvering to record turning circle, Reversing the yacht, bow thruster movements, yacht bearings amongst many other technical parameters.
If gauges are provided, then fuel consumption for the trial is also noted.
The above parameters are noted at regular intervals during the sea trial.
A functional check of the bridge equipment is also conducted during the sea trial.
5) Review of Documents
