If you're currently in the market for a new boat hull liner, you may be wondering which material is best for your boat. Below are descriptions of the most popular liner materials that will help you make an informed decision when purchasing your new liner.


As a result of being extremely lightweight and highly dirt-resistant, polyester is among the most popular boat hull liner materials currently available. In addition, polyester liners are able to stand up to excess UV rays better than other varieties of liner material. Furthermore, this particular material is very resistant to mildew and won't stretch, even in extreme temperatures.


While it is not as dirt-resistant or able to handle UV rays as well as polyester, cotton is a great material for anyone shopping for a boat hull liner on a budget. The type of cotton used for boat hull liners is fairly resistant to water, but as a result of not being able to withstand extreme heat or cold very well, cotton liners are primarily recommended for boats that are stored indoors.

Sunbrella Fabric

Sunbrella, a company famous for manufacturing durable, resilient outdoor furniture and awnings, sells a number of boat hull liners made from their special fabric. Like polyester, hull liners made from this unique fabric are able to stand up to extreme weather conditions and are guaranteed to give you many years of use, though they can be a bit pricey when compared to other liners.
