Hi, where I can see this new hull design you are writing of?
About planing-tail hull I read NACA reports on www.NASA.gov, you can easily find about 15 reports, here some links:
From my researches we can say that:
>Planing tail pro:
- great advantage in porposing range
- planing speed lower than conventional hull
- minimize trim range during take-off run (almost costant)
- high trim in take-off run, reduced field of vision during this critical moment.
- no rotation at take-off means or highest speed at take-off (with longer run) or best wing setup for take off but not optimal for cruise (I think, but a sperimental test should verify that last point)
>Conventional hull pro:
- low trim during plan
-rotation on Take-off means possibility for low take-off speed, and wing best setup imposed by cruise.(Here should be great to understand how long would be the run lenght for a conventional hull to reach minimum TO speed compared to the one for a planing-tail hull with wing setted up for cruise ).
>Conventional hull disadvantage:
- low stability range
- elevator control required for balance during planing run.
