Few of us would want to put our inflatable dinghy through such a test, but in fact, the daily rigors of being tender to a cruising boat are probably no less brutal. Ultraviolet radiation, rocky shores, and barnacle-covered pilings are notorious dinghy eaters. Oil, fuel, and other chemicals that we carry in our tenders can wreak havoc with most fabrics. With an eye on durability, we took a look at eight midsize inflatable boats that fold up or roll up for stowage. From five different manufacturers, these boats are just a small slice of whats available in this category, but they present a good cross section of the various types on the market. Along with the manufacturers featured here, the manufacturers of rigid-inflatable boats (RIBs) discussed in "Surviving the Great RIB Hunt" (October 2003) also offer several similar models of roll-up or fold-up boats.
