VFI Tech- nologies

VFI means Ventilated Flow interrupter, or stepped hull design. This is a unique stepped hull design with a solid profile, allowing the boat owner to have a much better performance than any other similar rib in its class.

Roughneck has applied the VFI technology to the whole range of its Ribs.Not every 'step' hull is created in this unique way, the right sea keeping characteristics are important. This requires an excellent understanding of water movement and boat design. With this technique Roughneck have manage to perfect and it has shown by the enormous international acclaim in recent years that has been expressed about our products.

The 555 (5 meter version) was a winner in 2003 and it is still the fastest product rib in the world. 636 (6 meter performance) was named best workable offshore Rib in 2005. The 808 (8 meter version) was recently in the news as the Roughneck factory boat came in first place in the 2009 European tour of the Offshore Ribrally. Winning by performance proves that the VFI technique works - Roughneck starts where others stop.
