There are an unlimited amount of cool aftermarket products to customize the Panther. The seats are off road suspension seats that are designed to absorb the big bumps and smooth out the ride no matter how rough the water or terrainmay be. The seats are made of stainless steel and marine vinyl so it is ok to get the interior really wet. But as with any marine product, corrosion is a major challenge. The WaterCar team has recognized and addressed the corrosion challenges from the very conception at every level possible. Everything that can be built with stainless steel is, everything else is epoxy coated or built out of non corrosive materials. The Panther is designed to be used in salt water as long as strict wash out and salt water maintenance procedures are followed.
