    Our current project is a 50' Wharram. It has design displacement of 33,000 lbs
    Power is two 150 hp Yamahas mounted amidships with 30" legs. I am wondering if Kort nozzles or ventilation plate wings will offer significant improvement in top speed.
    Wharrams are doubled ended with a tendency to pitch. I am wondering if some horizontal fins aft or on the rudders would help this and als help the boat use some of this power.
