Benefits of the Hydroflight^® Foil System

• Mitigates shock at high speeds in rough water
• Extends life of a watercraft
• Increases fuel efficiency and reduces fuel cost
• Reduces potential for injuries
• Reduces cost from equipment damage
• Increases stability and top speed
• Increases station holding capability
• Decreases pitch and g-loading by 50%
• Less wetted hull surface
• Compatible with v-bottom and Catamaran hulls
• Retrofittable for new and existing watercraft   more >>

Recommendations

"The foil system as tested appears to improve craft's performance in a seaway. The foil system prevents the bow from diving in a following sea or pitching in a head sea; reduces the g loading in a beam sea; and finally, increases the craft's speed at the top end. We recommend that the foil system concept be considered for application and evaluation of future U.S. Navy hulls."

- Quoted from NAVSEA Combat SYSENG-STA, Report No. 60-225, entitled Trial Results of 23 ft. Hydroflight with Foil System

How It Works

HFS attaches foils and tunnels to a V-bottom or Catamaran hull pursuant to a sophisticated patented design: Water lifts the bow hydrofoils which creates dense spray. This lifts the hull to create a cushion and suction effect that, compared to existing watercraft, testing has shown appears to significantly mitigate shock at higher speeds in rough water, reduce the potential for crew injuries, increase fuel efficiency, and reduce the cost of equipment damage.....more >>
