for a continuous luff support system, was derived by contracting head stay
and airfoil. Since the early seventies Head Foil® plastic luff support
systems, have, and are giving a competitive edge on small racing sloops to
large ocean racing sailing yachts.
Due to the improved light-weight honey-combed construction and refined
aerodynamic shapes, Head Foils have easily migrated to the new carbon and
FBO forestay rigs as a result of their light weight. Most recently
'Teton' (81' Reichel/Pugh) won this year
race. New developments continue to be underway to offer that
competitive edge for discerning sailors.
Refining Head Foils for aerodynamic superiority is our most important
objective. Two J/24s were used in sea trials for comparing the performance
of hanked-on jibs versus various shapes of Head Foils. Boat speed
calibration was preformed using "identical" sails and crew weight.
Significant boat speed increase was observed when a Head Foil® is applied to
one boat. The Head Foil®
test section is then switched from the faster boat to the "slower" boat,
again, with the same result. This observation was followed by water tunnel
experiments using dyes released upstream of aerodynamic sections being
tested. More details will be offered in our Product Development
section, with videos of the actual sea trials and water tunnel test
sections. This to be published in an updated site with newly developed
products where aerodynamics and Head Foil weights are compared with other
systems. Please refer to our product section to see our current
