When deciding on the right RIB, consider the design and material of each rib boat you look at is important. Hull layout include single-skin and double-skin. With a single-skin RIB, you walk on the inside of the hull bottom. But if you have a double-skin RIB, you walk on a flat floor inside the boat. Most manufacturers use aluminum or fiberglass to build RIB boat hulls. Aluminum RIBs are lighter than their fiberglass counterparts. However, aluminum rib boat tend to be noisier and even too light for rough waters. Many boaters enjoy the fact that aluminum is quite resistant against abrasions, making it a better choice over fiberglass rib boat.
