The ADVANCED ELEMENTS Dropstitched Inflatable Kayak Floor features drop-stitch technology that creates high pressure forms that are extremely rigid. Once a drop-stich floor is placed within the kayak, it creates a hull with chine, which is what enhances the tracking and hull speed. The Drop-stich floor provides the best in rigidity and stability and, once you install it, it stays put. There is no need to remove or re-install it with each setup and breakdown of the kayak. Additionally, if you are paddling a lot of shallow waters with hidden "surprises" beneath the water's surface or, if you'll be landing in heavy surf, the Drop-stitch floor is the way to go.
