How to extend the life of your yacht

The renovation never ends

No matter how good a yacht is, sooner or later the owner will face the need for repairs. Just like with an apartment, once you start renovations, you risk never finishing them. While renovations can be interspersed with long cruises, there will always be that one annoying little thing that will force you to disembark, roll up your sleeves, and continue the finishing work.

The secret to a smart repair, which will not only allow you to sail next season but also preserve your yacht for years to come, lies in the wise allocation of resources. The key is to address those critical issues that can have a real long-term impact, while keeping less significant problems manageable and receiving timely maintenance.

Refit as the meaning of life

One of the many options for keeping a yacht in good condition is a refit. This term usually refers to a superficial restoration, sometimes even a complete boat restoration. For brand-new yachts, a refit is generally unnecessary, but for sailboats and motorboats that are a good two or even three decades old, a refit should be performed regularly.

Shipyards and experts can help you accurately understand the need for restoration and maintenance work. Professionals will be able to assess the yacht's condition and the actual need for any work. 

By "serious investment," Gabriel means upgrading the yacht. According to the master, in terms of technology and hull strength, an older yacht will be significantly improved over its original condition. For this reason, it makes sense to choose an experienced master or shipyard capable of competently upgrading the boat and extending its life.

Where to start and where to go?

The typical sequence of events is as follows: an owner interested in reselling a yacht or preserving it for the long term contacts a shipyard or repair shop. There, an assessment of the yacht, the condition of its hull, and its components is carried out. A decision is then made as to whether repairs are needed immediately, whether restoration is on the agenda, or whether the matter is "not urgent."

Many shipyards spend a fair amount of time simply talking with the owner, as this allows for a deeper understanding of potential issues. However, representatives from Nathan Bone Yachts in Plymouth say that while a boat may appear fine and the owner will have no complaints, a more thorough inspection will inevitably reveal problems.

Of course, most yacht problems are primarily aesthetic. However, it's important to get to the root of the matter. Why is there mold on the teak deck? Why is rust gradually eating away at the plumbing? Why is the bilge so damp for no apparent reason? These and many other questions are far more important than cracked paint in the cockpit.

The deck and decking are particularly challenging. Visually, the decking, including the aforementioned teak, may appear to be fine. However, if a careless boat builder doesn't install the decking completely tightly, this will inevitably lead to problems with the deck and its integrity. Therefore, don't be fooled by the idyllic picture of a perfectly level deck.

What is hidden beneath the sea?

Another important part of any yacht maintenance is an inspection of its underwater section. It's the part of the hull below the waterline that can have serious structural defects caused by years of constant use. 

There's a significant advantage to refurbishing this part of a boat: work performed below the waterline is usually a one-time, long-term commitment. Therefore, if you need to replace just one seacock, consider replacing them all at once with higher-quality ones. By the way, what about the hose leading to that seacock? It will likely need replacing as well.

Careful attention should also be paid to repairing/restoring the keel and rudder blades. Skimping on keel base washers, for example, is definitely not a good idea, nor should you neglect additional anti-fouling treatment or osmosis. 

Don't skimp on components

The key to truly extending the life of a yacht is using high-quality, certified equipment. It doesn't have to be brand-name, but it definitely needs to be of good quality. The longer components and consumables last, the fewer problems you'll have with subsequent repairs and maintenance.

Batteries and accumulators

Lead-acid and AGM batteries typically last only 3-5 years, after which sulfation sets in. However, lithium LiFePO4 batteries, with proper care, can provide stable operation for another 10-15 years.

Standing rigging

Stainless steel cables are typically replaced every 7-10 years, and this is often required by insurance. Modern Dyneema rigging (specifically, the creep-resistant DM20), when properly insulated and protected from the sun, can last ten years or even longer.

Sail

Standard Dacron lasts about 7-10 years with moderate seasonal use. Materials reinforced with Hydranet or Dyneema last significantly longer—sometimes up to 12-15 years—before shape loss makes replacement inevitable.

anchor chain

With active use, a galvanized chain usually requires replacement after 5-10 years, while stainless steel can last for over two decades.

Kingstons

Brass seacocks can lose their integrity after just five years, while bronze models or Marelon valves often last as long as the yacht itself.

Deck equipment

The same principle applies to fittings: inexpensive plastic units quickly wear out and start to jam, while a well-maintained bronze or stainless steel winch is an investment that pays off in longevity.

Electronics

Magnetron radars lose efficiency after about 5-7 years, while solid-state Doppler systems do not have such age-related problems.
