There are very many points on a yacht that will need to be examined when a vessel is surveyed.What are the main points that the yacht surveyor will look for?One of the obvious is the construction of the hull and bulkheads. He will also want to check to see if the boat is showing any signs of Osmosis.How does a yacht surveyor check a sailing yacht hull for Osmosis?
They will initially look carefully along the hull of the yacht for a rash, discolouration or blisters.Then by using a moisture meter designed for GRP (Glass Fibre Plastic) they will read the moisture content. The newer types of meter read the conductivity through layers of antifouling.Probably some of the antifouling will need to be removed in various places on the boat hull so as to be able to see what state of condition the Gel coat is in.How does one judge what is an acceptable moisture level? The best way of answering that question is to take a reading with the moisture meter of the deck and topsides which will then provide a base line to work from as no two boats were moulded with the same mix or make of resin, then systematically check the exterior of the hull starting at the waterline in the area of the keel and in some yachts the rudder. Usually a higher reading is found on or around the waterline and in motor cruisers the transom.A surveyor will naturally take into account the type,manufacturer and age of the vessel to give you an accurate opinion as possible.If a boat that you have short listed has survey results that
showsigns of Osmosis does that mean that you should not proceed? Well it is something that you must take into account together with the age, type, price and general condition before saying no as Osmosis is repairable, but at a cost of both time and money.After examining the Hull the topsides and superstructure is very carefully examined again looking for signs of crazing, damage, and decking which appears soft, again taking into account the type and the age of theboat.Rigging should not be over tightened as bottle screws are easily over tightened and will put undue strain on the standing rig, mast and hull of the yacht. Quite often the first signs of over tightening is that the doors to cabins do not open properly.The inside of the hull and bilges will be examined by looking under all openings for signs of stress cracks or delamination around bulkheads and cross members.Water in the hull of the boat will add to the problems of Osmosis.Carefully examine and test all sea valves pipes and clips for operation, corrosion and security. If a jubilee clip is rotten and or the seacock is faulty you could not only lose the yacht but also your and the crews life.Engines and related machinery should be tested by an experienced marine engineer as to condition, as just because the engine starts and runs it does not guarantee its condition in the future.It is good practice to start the engine/s from cold examining all fluids for signs of contamination, and a full trial at sea including running the engine at various speeds including at maximum revs for a short while.Only after these and many more tests can you assess the true state of marine engines.The above is just a small amount of what a good yacht surveyor will look for.Many times people enquire what is the best idea when buying a used boat.Here are some brief tips to help.1. Take your time and sleep on it as this yacht will undoubtedly still be on the market in the morning. Also take one last look at what else is on the market before you finally decide.2. Is this sailing yacht really correct for me in all material points? Is it the right size for all my requirements?3. Be very careful as with many things in life all that glitters is not gold.4. Never finalise a deal until you have had a full boat survey and had the opportunity to discuss it in detail with your surveyor.5. Lastly what ever you do please recall that latin phrase “Caveat Emptor” buyer beware which is the best possible advice before purchasing a second hand yacht.
