That is how many boats are made, they use resin and reinforce with fiberglass. To put it simply, it’s plastic that has been reinforced. They later started adding it to more models of PWCs, and now it’s more than half it’s line uses this material. The Sea-Doo Switch is different from other boats and pontoon boats as it uses a Polytec hull and not fiberglass or aluminum.Ī Polytec hull is not something new, Sea-Doo has been using it on the Spark since 2014.
