#467 IMS 53
YELLOW JACKET (x Bribon) was our fourth design for Jose Cusi-Ferret to
be skippered by HRM Juan Carlos of Spain. Their requirements
were a boat comfortably faster than the current 49 footers
in the 12 to 18 knot wind range typical of Palma. The key
characteristics that set this boat apart from our previous
generation of IMS designs are the short-footed headsail rig
with in-line spreaders, the cruiser/racer interior and deck
layout and the hull shape developed using the results of an
extensive testing program that employed the CFD program SPLASH.
The result is a 53’ boat that has the rig flexibility
required for the ever-changing wind conditions of the Med
and handicaps that fall in the middle of the 49 foot fleet.
The rig combines the handicap and handling advantages of the
short-footed headsail with the advantages of in-line spreaders,
runner and checkstays, namely better upwind sail-control and
the ability to let the mast forward downwind.
