If you're planning to get a new deck on your boat, and you've chosen teak, a composite deck, or a cork alternative, this guide will walk you through the full process, from digitization and manufacturing to final installation so you’ll know exactly what to expect from start to finish. TEAK DECKS Digital Templating The first stage involves one of our technicians digitally templating the area using the latest in precise measuring technology. Our team digitally templates vessels all around the world. Engineering Our experienced designers are masters of creating beautiful and technically precise decks using CAD construction program, importing data provided by our digital templating team. Our designers’ exceptional ability to create visual symmetry ensures impeccable finishes and beautiful aesthetic decks. Manufacturing TDS panels are manufactured in our factory utilizing jigs that are adjusted to conform to the vessel’s shape. Teak planks of the required thickness and width are carefully hand inspected, scrutinizing each plank for grain orientation, mineral deposits, or imperfections such as a small knot. The planks are placed into the jig in such a way that the finished deck will have a uniform butt joint pattern. Creating a Watertight Barrier A phenolic or fiberglass backing is securely vacuum bonded to the teak, using our own epoxies that guarantee durability, flexibility, strength and reliability. The exceptional bonding strength, ensures your deck stands the test of time. After the epoxy cures, the newly formed panels are removed from the jig, and the seams between the planks undergo routing, cleaning, and caulking. Margin Trim Once the caulking is cured, the final step involves laying out the teak deck and laying all the margin trim. Upon completion, the finished deck undergoes a thorough quality inspection, ensuring it aligns precisely with the template. Transport & Installation The finished deck panels are placed in custom-made crates and then shipped and installed worldwide. Prior to the arrival of the new deck, the old deck is removed. Our installers inspect for any issues such as water intrusion, delamination, or corrosion on the vessel’s surface. If such issues are found, the areas are repaired before the new deck is installed. Caulking & Sanding Once the deck has been bonded to the vessel, it is time to caulk using our own proprietary, UV, and chemical-resistant caulking TDS SIS-440. After curing, the deck is then ready to be sanded. The entire deck is sanded with 36 grit to remove excess caulking, followed by 60 and 80 grit to enhance the look of the deck. COMPOSITE DECKS Digital Templating The first stage involves one of our technicians digitally templating the area using the latest in precise measuring technology. Our team digitally templates vessels all around the world. Engineering Our experienced designers are masters of creating beautiful and technically precise decks using CAD construction program, importing data provided by our digital templating team. Our designers’ exceptional ability to create visual symmetry ensures impeccable finishes and beautiful aesthetic decks. Manufacturing Every composite decking panel is custom made to perfectly fit the areas to be covered. The panels are delivered with completed seam pattern, sanded and ready to be glued down on most structural surfaces. In the case of SeaSole, the deck is installed using the “peel and stick system”. We use a combination of our TDS bedding and bonding adhesive, along with TDS two-part, flexible epoxy fitting glue, to secure the panels in place. The caulking in the seams is our TDS proprietary patented filler, an enduringly elastic, solid rubber polyurethane joint sealant. Our team will first carry out an inspection of the boat to identify the best application method for each area. Quality Control Once the caulking is cured, the final step involves laying out the composite deck and building all the margin trim. Upon completion, the finished deck undergoes a thorough quality inspection, ensuring it aligns precisely with the original template. Installation The finished deck panels are placed in custom-made crates and then shipped and installed worldwide. Prior to the arrival of the new deck, the old deck is removed. Our installers inspect for any issues such as water intrusion, delamination, or corrosion on the vessel’s surface. If such issues are found, the areas are repaired before the new deck is installed.

What to expect from TDS when you order a deck Once you have decided to order your new deck from us, we have a process in place to ensure that the whole manufacturing and installation goes as smoothly as possible. With a commitment to transparency and customer satisfaction, we have put together some guidelines outlining the most important key steps from the moment that you commit to a new deck from us. 1. Customer Inquiry, Quotation Process and Formal Quote When we are first contacted by a customer, we ask that they send us photos and a layout of the boat via our contact page on our website so that we can understand their specific requirements. Our team then conducts its own research by reviewing the layout and photos provided, as well as gathering information about your boat. Based on this information, we develop a budgetary quote, and if the customer is satisfied with it, we provide a formal quote. The formal quote outlines all the essential details, including design specifications, materials, price and timelines. It is crucial that you read through this document carefully. Taking the time to review it not only helps you understand what to expect but also gives you an opportunity to ask questions or clarify any uncertainties before signing. Once the quote is acceepted, we issue a pro forma invoice for the templating/digitizing, after which we will organize a date to digitize the deck. Once we have the digital file, our sales and project management teams meet to review both the quote and the digitized layout to ensure that the quoted square footage is accurate. Should there be any discrepancies, we adjust the quote accordingly and will call you to explain the changes. 2. Securing Your Order with a Deposit After both parties agree on the final numbers, we send an order confirmation for your signature and will then send an invoice for 50% of the materials cost and the cost of digitization so that we can begin building the deck. Once the funds are received, we start production, later invoicing for the remaining 50%. Travel costs associated with the digitization are invoiced separately after the activity has concluded. 3. Project Management and Timeline Confirmation We will assigns a dedicated Project Manager to your deck, and they will be your primary point of contact throughout the entire process. Your Project Manager is responsible for confirming the production and installation timeline and ensuring that every phase of the project is scheduled appropriately. They will communicate any updates, answer your questions, and address any concerns that may arise during production. 4. Final Payment and Scheduling Shipment Before the deck is shipped and installed, we require that the full remaining balance is settled and we can then schedule shipment and installation without any delays. 5. Installation You will have received an estimated quote for installation. Once the deck is installed we ask the captain or project manager to walk the deck with our team and get a sign off and release for the deck and then we invoice them for the final amount along with any associated travel, travel time, accommodation and subsistence. We will invoice you the final amount once the installation has been done.

The yachting community has long held the belief that viable teak must come from very old, natural forests, with much of the industry still adhering to the notion that teak must be 100 years old. Despite the environmental and humanitarian controversy surrounding teak, many owners worldwide continue to request it. This guide explores the different wood materials currently available , helping industry stakeholders and owners to make informed decisions about the best option for their deck . The information is divided into two sections titled "Wood we work with" and "Wood we do not work with." It is intended solely for educational purposes, providing detailed information on the characteristics, merits and concerns of each type. As a leading deck builder and installer, TDS remains completely impartial with no vested interest in any of the products discussed in this guide. MYANMAR TEAK The importation of Myanmar teak into Europe has been illegal since 2013 under the European Union Timber Regulation (EUTR), which aims to prevent the sale of illegally harvested timber. In 2021, additional sanctions were introduced that further restricted its availability, extending the ban to the USA as part of broader efforts to curb deforestation and human rights violations linked to the Myanmar timber trade. That same year, the Council of the European Union imposed targeted sanctions on Myanmar’s military regime, specifically restricting its ability to export timber that serve as key revenue sources for the junta. Despite these restrictions, Myanmar teak continues to be traded in countries that do not enforce such sanctions, including India, China, the UAE, Turkey, and Australia. Note, these restrictions may change at anytime. WOOD WE WORK WITH PLANTATION TEAK Characteristics Less dense than old-growth, natural teak. Younger trees aged between 30-50 years. Is resistant to insects and rot. Merits Despite the shorter and narrower planks, we can still get 20mm thickness and planks up to 2.2m. By using scarf joints or finger joints we can create 4m battens that are glued together. Shorter planks also reduce the purchase price. A guarantee that the forest is managed in an environmentally responsible and sustainable manner, including practices such as replanting trees, protecting biodiversity, and minimizing environmental impact. Verifies that the teak is sourced from legal and well-managed forests, reducing the risk of illegal logging, and complying with international law. The teak undergoes rigorous quality control measures, ensuring it meets certain standards for durability, strength, and appearance. Social Responsibility is at the heart of the activity, including fair labor practices and community engagement, supporting local communities, and ensuring workers' rights are respected. Plantations are managed with long-term sustainability in mind, ensuring a reliable and consistent supply of teak. Well-managed plantations, act as carbon sinks, helping to mitigate climate change by absorbing and storing carbon dioxide from the atmosphere. If properly maintained a deck will last 15-20 years. Concerns Some plantation teak is harvested too early for quality yacht decking. Less growth rings, resulting in lower grain quality. Less density that can give rise to warping and bowing. Pin knots are a consequence from pruning lower branches. Plantation managers, governments are reluctant to direct resources towards certification schemes. Where to source it? India, Indonesia, Tanzania, Benin, Brazil, Thailand, Sri Lanka, Costa Rica, Trinidad Note: there are other countries with younger 15-20 year teak. CERTIFIED GREEN TEAK Characteristics Uses parts of 30-40 year-old trees that would normally be rejected due to knots and imperfections. Sliced into thin veneers and glued together, to form a modified material with superior strength. Lengths up to 4m and allows large widths due to laminations Aesthetically attractive, with a plank like finish. Excellent durability as the laminating process enhances its stability and dimensional integrity. Is resistant to insects and rot. Merits The veneers are similar to the vertical grain of natural teak. Yield about 85% of the log vs 2-15% of log for Vertical Grain Renowned for its hardness, strength, and durability. A test panel currently on a yacht, had a 10kg scaffolding pole dropped onto it, causing only a 2mm dent. Limited susceptibility to cracking and warping, when cut and dried correctly. Non-skid surfaces. Extra insulation in hot and cold climates. A well-maintained deck should last 15-20 years. Concerns It may have variations in color and texture due to differences in the wood grain and moisture content of individual layers. Ensuring the quality and integrity of the bonding process is crucial, as poorly bonded laminations can lead to delamination, weakness, and structural issues over time. While lamination can improve the stability of green teak, the overall durability and longevity of green laminated teak may still be inferior to properly seasoned teak. It still requires careful moisture management to prevent swelling, shrinkage, or damage over time, especially in environments with fluctuating humidity levels. In some cases, the adhesives used in the lamination process contain chemicals. Where to source it? Thailand THERMALLY MODIFIED WOODS ACCOYA Characteristics Certified sustainable fast-growing softwood “Radiata Pine” is its base material. The wood is acetylated using acetic anhydride and water. It makes the wood virtually unable to absorb water, expand and rot. Merits Extremely durable, they guarantee it will last 50 years for use above ground and 25 years for use below ground. The wood can be reused, recycled, or burned as biomass (fuel). A great option for certain vessels such as catamarans. Very low maintenance. Concerns The color is different to what the industry “expects”. Its not as hard as teak, as it still has a lot of softwood. Where to source it? The Radiata Pine is harvested in New Zealand and shipped to the Netherlands for the modification process. TMT MARINE LIGHT Characteristics Significantly cooler than teak. Much lighter than teak. Similar abrasion resistance as natural teak. Merits Very dimensionally stable. Resistant to shrinking and swelling due to humidity, temperature, and moisture content. Resistant to decay and insects. Large logs that produce long, wide boards with tight, vertical grain. Can be used for interior applications, accepts stains and finishes. Fast-growing, sustainable species. Durable, slip resistant surface that is excellent for marine conditions. Concerns Much lighter in color, almost white before weathering. Soft wood that needs to be carefully sanded to remove scratch marks. Limited availability. Prone to splitting, chipping, and splintering requiring high quality tools and sharp blades when working. Where to source it? Western United States and Canada. WOOD WE DON'T WORK WITH THERMALLY MODIFIED WOODS AMERICAN HARD MAPLE Characteristics Specifically created for the marine industry Thermally modified by a controlled pyrolysis process of the wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components; lignin, cellulose and hemicellulose which increases its durability. Merits No chemicals are used during the modification process. It looks like teak. It weathers to grey in the same way as teak. Claims a zero-carbon footprint. Concerns Cracking. The color of thermally modified maple can vary depending on the specific treatment process and wood source, which may affect its suitability for certain design schemes. Where to source it? USA. TESUMO Characteristics Fast-growing African tree that matures in 50 years. Sourced from certified managed forests. Modified using heat, resin infusion and drying. Merits Developed as part of a research project conducted by Lürssen Shipyard and the German University of Göttingen.Can be disposed of by burning. Tested for years on land and at sea. Similar appearance, dimensional stability and rot resistance as teak. Concerns Limited amounts available. Where to source it? Germany. IROKO Characteristics African hardwood native to West Africa. Is resistant to rot and termites. Long, wide boards. Merits Similar color to teak. Economically priced. Concerns Extremely hard wood to work with: produces an enormous amount of fume and dust, prone to splintering and blunts work tools. Susceptible to cracking. Requires a lot of maintenance. A deck will last 5-6 years. Where to source it? West Africa. LEGAL DISCLAIMER This document is for informational purposes only and does not constitute professional, legal, or environmental advice.
