Duo Delta Conic High Speed Planing Hull
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.
