From Personal Belly Boats to High Performance Racers - An Overview of Inflatable Boats

Inflatable boats, also called rubber boats or dinghies, have been around in one form or another for thousands of years. They now come in many different sizes and models and include inflatable kayaks, sport boats, and inflatable catamarans. Their versatility and relatively low cost have contributed to their popularity, and more and more water enthusiasts are discovering the advantages of owing an inflatable boat.

Evolution of the Inflatable Boat

Historical records indicate that the first inflatable boats were animal skins filled with air. Over the years, many cultures have created various versions of inflatable watercraft, and in 1839, the Duke of Wellington tested the first inflatable pontoons. In the decades that followed, many new designs were introduced and some of them were utilized by European military forces.

The inflatable boats were used to transport torpedoes and other cargo. They also allowed troops to make discreet landings in shallow water, and their compact size and storability made them easy to bring with, even on overland marches where it would not have been possible to bring a traditional boat.

One of the models, the Zodiac, grew to be very popular with the military and contributed significantly to the rise of the civilian inflatable boat industry, both in Europe and in the United States. After World War II, surplus inflatable boats were sold to the public and the general population had a chance to experience how easy and enjoyable these boats can be.

Since then, inflatable kayaks, sailing inflatables, inflatable canoes, sport boats, and belly boats have been added to the mix. Some inflatable boats run 45 feet in length or more and may include inboard steering, luxury features, and even full cabins. Inflatable boats have evolved so much that today, the only thing inflatable on some boats is the collar around the perimeter gunwales of the deck.

Hull Designs & Types of Inflatable Boats

Inflatable boats come in rigid hull design and soft-bottom style. Soft-bottom boats have floors made of fabric and slats (usually wood) running across the beam. This design is generally found in smaller inflatables ranging from about 6 to 8 feet in length only.

Rigid hulls, or RIBs, were introduced in 1967 by Tony Lee-Elliott and advanced by Admiral Hoare and the Atlantic College in Wales. As opposed to soft-bottom boats, which have a fabric hull with inflatable or wood keels, RIBs have hard fiberglass or aluminum hulls and large, inflatable tubes. This allows for a combination of the best features from both types of boats.

Some RIBs incorporate the V-shaped bow similar to that of a traditional boat. This design consists of a separate inflation tube running the length of the boat beneath the floorboards. Once inflated, it pushes the floor materials down to form the V-shape that helps in steering. The flotation collars on many RIBs are removable, making them easier to store and to clean.

RIBs typically range from 10 to 30 feet in length and are propelled by either by an outboard motor or an inboard motor turning a water jet or z-drive. They were first used as lifeboats in 1970, and later as dinghies or tenders on larger pleasure yachts. Many of today
