Why yacht builders are scrambling to replace teak decking

/ Technology / By

Teak has been the gold standard for yacht decks for decades: it grips when wet, resists rot and salt, and signals “luxury” from across a marina. But the yachting industry is now being pushed—by law, by supply constraints, and by reputation risk—to find alternatives.

The basic problem is that the highest-quality teak historically came from old-growth forests in Myanmar, and that supply is now entangled with sanctions, legality checks, and sustainability concerns. As stockpiles dwindle, builders are testing materials that try to mimic teak’s performance without the same supply-chain baggage.

Why teak became the default in the first place

Teak isn’t just pretty. Its natural oils and dense grain make it unusually durable in harsh marine conditions. It handles:

  • Constant wet/dry cycles
  • UV exposure
  • Salt spray
  • Foot traffic and abrasion

For deck use, those properties matter more than “wood as decoration.” A yacht deck is a working surface that must stay safe, stable, and low-maintenance.

The Myanmar problem: legality, sanctions, and traceability

The BBC reports that old-growth teak is harvested from natural forests in Myanmar and sold through a military-linked sector. After the 2021 coup, sanctions hit the trade, and importing Myanmar teak is illegal in the UK, EU, and US.

Even when a buyer claims teak is “plantation” wood from elsewhere, verification is difficult. In practice, wood can move through intermediaries and be relabeled—so yacht makers have to prove not only what they bought, but where it truly originated.

That’s why the story around high-profile yachts matters: a single investigation can become a case study in whether the industry’s due diligence is real or performative.

What “alternatives to teak” actually means

There isn’t one substitute; there are categories, each with its own compromises.

Thermally modified wood

Thermally modified woods use heat (and sometimes additional processing like resin impregnation) to change the behavior of a different wood species so it acts more like teak.

The BBC highlights Tesumo, developed via a research effort involving the University of Göttingen and the Lürssen shipyard. The approach aims to deliver teak-like looks and durability while using a fast-growing hardwood rather than slow-grown old-growth teak.

Why builders like it:

  • Can be made to look similar to teak
  • More consistent supply than old-growth teak
  • Potentially better thermal behavior on deck (cooler to walk on)

What can go wrong:

  • Long-term marine aging is everything; small differences show up after years
  • Repairs and refinishing can be less familiar to yards and owners

Synthetic “teak” (PVC and similar)

Synthetic decks (like PVC-based products) replace wood with a material designed to resemble it.

The upside is predictability: you don’t have grain variation, knots, or traceability issues. The downside is that owners who want “real wood” often don’t accept it, and there are broader concerns about plastics in the marine environment.

Engineered teak laminates

A clever middle ground is using plantation teak more efficiently. By slicing and laminating thinner pieces, you can “use more of the log” and produce boards that visually read like higher-grade teak.

This doesn’t eliminate teak from the supply chain, but it can reduce pressure on scarce, high-grade stock.

Why culture change is as hard as material science

A recurring theme is that buyers ask for teak by default. That demand shapes what yards offer, which shapes what suppliers stock.

The industry’s shift may therefore hinge on two things:

  • Owners trusting that alternatives aren’t “cheap”—they’re responsible
  • Builders proving performance with real-world installs, not showroom samples

Bottom line

The yacht industry’s teak scramble isn’t just about decking—it’s about traceability, sanctions compliance, and whether luxury goods can adapt when their traditional “premium” materials become legally and ethically fraught.
