9 feet to 12 feet Rigid Inflatable Boats With or Without Front Storage Rigid inflatable boat is defined as a hard-hulled boat with air inflatable collars. RIB hulls are made of fiberglass, aluminium or composite materials. The soft bumpers called "sponsons," can be air tubes with a number of air chambers inside, or all foam systems. These boats are powered by a variety of motors. This boats are width 930, Over length 2700, Hull length 212cc, Number of passengers ride 4 to 6. Hypalon material is used when conditions require heat resistance such as in southern climates. Rigid inflatable boats are more like traditional boats, with V hulls supported by a rigid material. The main benefits of these boats are light weight, superior performance and easy assembly. To assemble, one simply has to inflate the tubes. However, storage can be a problem because they can't be made smaller than the rigid portion of the boat. Many yachts use a davit system to bring launch and bring it back onto the larger boat.
