The DDC is a revolutionary new hull design that incorporates two hulls
in one. The forward Delta Conic hull has a developed conical entry with
a constant delta planing. It also incorporates wide lipped chines. The
aft hull develops a constant planing surface that displaces a delta
pattern when on plane. The forward hull creates a bow wave under the
hull, along the aft hull to "ride the wave". As speed increases, the
wave moves aft thereby lifting the stern. The hull then lifts to planing
attitude without climbing over the "traditional hump".
At rest or on plane the trim attitude is
nearly the same as during acceleration (no hump). The DDC has a high
degree of lateral stability as a result of the forward chine notch. As
planing speed is achieved air is vectored under the running section
thereby reducing suction loads, as illustrated in the graph on this
page, The forward and aft hull planes at optimum angles. The aft hull
"surfs" on the bow wave at high speeds. This performance characteristic
eliminates the need for trim tabs or wedges. Thus the DDC achieves
higher speeds, greater efficiencies and stability, soft ride and
effortless control. |
