"Island Packets all have Full Foil
Keels®, which were developed by Bob Johnson
in the 1980s to gain the practical benefits
of a full keel with the lift characteristics of a
foil-shaped keel. The end result is a keel that
will take a grounding easily and will protect
the propeller from flotsam while at the same
time providing the boat with an easy motion
through the water and excellent directional
stability. In an age when lightweight hulls
with fin keels and spade rudders are the
standard, the Full Foil Keel® stands out as a
unique innovation."
