In the 21st century, yachts and their decks are built of metal, composites, or wood. Most structural deck surfaces are designed to be covered in custom decking and then permanently bonded with strong flexible adhesives to the structural decks. An intermediate layer of closed-cell foam-board or marine plywood is sometimes added between the metal and teak deck as an interface and/or to increase the insulation and sound reduction. These surfaces are known collectively as ‘substrates’.
THE DECKING PROCESS
Introduced by Teakdecking Systems in 1983 Modular deck systems are teak planks that are assembled as large panels with seams that are pre-caulked to form sections. Templates are fabricated on the vessel to ensure a perfect fit. These templates may be created digitally or by a traditional method of hot gluing strips of thin plywood together.
Once the panels are assembled and cut to shape, they are delivered to the boat’s location and the modular deck is completed by fitting and cutting the trim boards around the perimeter of the deck. This process revolutionised the industry and is today’s standard.
MAINTENANCE PROCEDURES & PRODUCTS
Once installed, oxidation and UV load will take their toll over time on the deck’s surface, along with normal environmental soiling, plus, the sealants and adhesives that hold the deck together.
A silver patina is the natural state of teak in the marine environment. Trying to reproduce the look of ‘boat show teak’ that has never been in the sun is a profitless endeavor. Teakdecking Systems recommends maintaining decks in a natural state without oils, sealers, or other topcoats. If deemed necessary, waterborne or low V.O.C. products are recommended such as Teakdecking Systems Sealer and Protector, along with ECO cleaners.
