Recently, stand-up paddle boards (SUPs) have found their way out of “Obscure Sports Quarterly” and into the mainstream. Numerous companies manufacture this tender-meets-water toy, but the six-inch-thick Adventurer inflatable paddle board ($699) by Tower may be the best bet for boaters looking to give the sport a try. Two inches thicker than most SUPs, it provides extra stability with a load capacity north of 400 pounds. The soft rubber composition of this practical platform allows crew members to detail a yacht’s hull without leaving a scratch or scuff. This 12-foot-long by 30-inch-wide board can be deflated and rolled up like a sleeping bag for easy stowage in the lazarette.
