Hull & Tubes

Superior hull design

The modern Tornado hull design is the evolution of more than 40 years of testing, upgrading and modification, which has resulted in a Tornado range of boats consisting of 4 different models to suit every need, from the small lake runabout RIB to the 12m Commercial Tornado RIBs currently operating in some of the harshest environments. This wide range of use is especially due to the strength of the hull, which is in the fiber reinforcements and not directly in the resin (but the resin must be strong of course, as this is what binds it all together), and at Tornado Boats we use a combination of polyester and vinyl ester to get the strongest and lightest boats.

Tornado’s advantage

What gives the Tornado RIB an advantage over all other RIBs on the market, is the classic V-design of the hull. This design has demonstrated its durability and strength for over 4 decades, mainly because it maximizes the speed of the RIB while economizing fuel consumption, as well as providing supreme safety, maneuverability and versatility.

Extremely durable tubes

Choosing the correct material for the tube construction is one the most important decisions when building a RIB, which is why all Tornado tubes are made of the best PU fabric available. PU or Polyurethane material has far superior qualities of abrasion resistance and the ability to cope with extreme temperatures, and this PU material (in 2 different weights) has the unique advantage, that it also allows any general fittings, strake, cladding, handles or lifelines to be glued to the tubes. To add to the quality of the production, all our seams on these high class RIB Tubes are welded, a production method that makes the seams almost as strong as the fabric itself and far stronger than glued seams.

Best materials available

As with all Tornado production, we have chosen the best production methods and materials, not the easiest and cheapest. Every custom-built Tornado is hand crafted using the highest grade marine materials on the market, and as one of the few RIB manufacturers in the world we manufacture our own pontoons from 100% Polyurethane fabric. A material that is far superior in every way to common fabrics like Hypalon and PVC, which is also why Polyurethane is especially recommended by military experts for professional RIBs. In 1993 the U.S. Naval Surface Warfare Center did a study on polyurethane and the advantages of using it for Rigid Inflatable Boats. The Technical Memorandum concludes: “The data shows that the Urethane coated fabric is considerably stronger than the Hypalon® coated fabric.”

The Memorandum also states that: “(. . .) Polyurethane is more correctly defined as an elastomer, meaning, it can be repeatedly stretched and still recover to show its original properties – a significant benefit for RIB tubes that are often subjected to major stresses during wave impact.”

And it recommends: “Urethane coated fabrics should be adopted as a replacement for Hypalon® coated fabrics in tube construction on U.S. Navy RIBs.”

Another study, also by the U.S. Naval Surface Warfare Center, confirmed those results in 2001 and further stated that: “Tubes constructed of polyurethane coated fabric exhibit better key physical properties than tubes constructed of Hypalon coated fabric (…), better tensile strength, tearing strength, puncture resistance, coating adhesion, and abrasion resistance.”

Polyurethane facts:

– Polyurethane has a very long service life.
– Very high mechanical strength against wear and tear as well as point loads.
– High resistance to UV.
– Exceptional air-tightness.
– Rarely punctures.
– Easier/less time-consuming to repair compared to other materials.
– Resistant to most solvents like oil and petrol.
