Rigid Hull Inflatable Boats – The Ultimate Guide

Introduction to Rigid Hull Inflatable Boats

Rigid hull inflatable boats—or RHIBs—are designed to combine the strength of a hard hull with the buoyancy, stability, and shock absorption provided by inflatable tubes. This fusion creates a craft that is lightweight yet robust, making it an ideal choice for tasks that demand reliable seaworthiness. Originally developed for search and rescue operations, RHIBs have since branched out to everything from leisure cruising and fishing to law enforcement and commercial transportation.

Novelli Boats takes this proven RHIB concept a step further by incorporating advanced hull designs, computer-aided engineering (CAE), and premium materials like 5083 marine-grade aluminum. Our mission is to produce rigid hull inflatable boats that not only excel in performance but also deliver a luxurious, comfortable experience for every passenger.

The History and Evolution of RHIBs

The concept of a rigid hull with inflatable collars began to gain traction in the mid-20th century, largely attributed to rescue and patrol organizations needing a dependable boat that could handle various challenges. Traditional inflatables offered high buoyancy but lacked the structural integrity required for rough seas, while standard fiberglass or metal hulls provided durability but didn’t have the same buoyancy advantages. By merging these elements, marine engineers created RHIBs.

Over time, advancements in materials such as Hypalon, PVC, and aluminum alloys have further improved RHIBs, making them lighter, stronger, and more versatile. Today, RHIBs are ubiquitous in professional maritime scenarios—used by coast guards, military forces, dive operators, and adventure tour businesses worldwide. Novelli Boats stays at the forefront of this evolution, integrating AI-driven design and robust construction to create future-ready RHIBs.

Foam-Filled vs. Air-Filled Tubes

Traditional RHIB designs rely on air-filled tubes, known for being lightweight and easy to deflate for storage. However, foam-filled tubes are gaining popularity for their robust and nearly puncture-proof qualities. Novelli Boats offers foam-filled collars because of the added safety and buoyancy they bring. Even if the outer material is compromised, the foam remains intact, keeping the vessel afloat.

While foam-filled tubes can weigh more, the trade-off in reliability is often worth it, especially for rescue, commercial, or offshore applications. The added insulation also dampens noise, delivering a quieter, more comfortable experience for passengers.

Engine and Propulsion Choices

Most rigid hull inflatable boats use outboard engines, though inboard or jet propulsion systems can be applied in specific, usually larger-scale, builds. The ideal engine depends on factors like boat size, typical passenger or cargo load, and intended usage (speed, distance, or specialized operations).

Novelli’s approach to engine selection involves matching horsepower to the hull’s weight and design. Because our aluminum hulls are lightweight, you can achieve impressive performance without overspending on high-powered engines. This balance translates into cost savings both at the point of purchase and throughout the lifespan of the boat via fuel efficiency.
