SwellUP works a bit like magic, but we’ll call it science so we don’t freak anyone out. It uses a unique system with a storage base and inflatable structure (yes, inflatable) to evenly tighten your boat cover across the entire surface. Water pooling? Not on SwellUP’s watch. It can’t tip over, and don’t worry about getting it perfectly centered. It keeps your boat cover secure and free from rips or tears in all kinds of weather. Oh BTW, that’s not all… #3 is worth a read.
