Types of boat teak decking: natural, plantation, synthetic and alternatives
Quick answer
There are four main deck options: old-growth natural teak (densest and most expensive), plantation teak (more affordable and sustainable), PVC or composite synthetic teak (low maintenance, lower price) and marine cork (light and cool). Natural teak gives the best feel and resale value; synthetic the least upkeep.
Natural teak (Tectona grandis)
The traditional deck timber. Natural oils and silica make it highly resistant to water and rot, and non-slip even when wet.
- Old-growth teak (Burmese/Myanmar type): very tight grain, high density and stability. Trade is heavily restricted, so it is scarce and expensive; make sure it has proof of legal origin.
- Plantation teak: grown in Asia, Africa or Latin America. Faster-grown with a more open grain and slightly less oil, but more affordable and sustainable (look for FSC certification).
Synthetic teak
PVC or composite panels that imitate teak, made to measure and bonded like the real thing.
- Pros: almost maintenance-free, no sanding, lower price, uniform look.
- Cons: gets hotter in the sun (especially darker colours), different feel and less added resale value.
Marine cork and other alternatives
Cork is light, insulating and cool underfoot with good grip. Less common but growing on modern boats. Alternative timbers (such as iroko) are used for interiors or non-exposed parts.

Which should you choose?
- Classic or high-end boat: natural teak; it adds value and buyers expect it.

- Tighter budget and sustainability: certified plantation teak.

Frequently asked questions
Is natural or synthetic teak better?
It depends on use. Natural teak has a better feel and grip and adds value but needs more care. Synthetic costs less and needs little maintenance, although it gets hotter in the sun.
Can synthetic teak be sanded?
Usually it doesn’t need to be; clean it with soap and water and, for stubborn marks, a very light sanding as the manufacturer recommends.
