I NOW some of you guys love to "do the math", "use your experience" or simply "make a best guess" !! 
Assume hulls 1.,2. and 3. are the same hull. Weights of all 3 hulls are the same.
One of my "virtual DEs" can swing up to a 28" prop.
Here is the known data (1. and 2. ) of same hulls
1. 440 hp 3300 rated 2:1 gear 24X26 with #4 cup
2. 420 hp 3000 rated 2:1 gear 24X35 no cup.
3. Bill D's "virtual hull"
480 hp 3400 rated 2.5 : 1 gear..... what prop ??????????
Hulls 1. and 2. go plenty fast enough @ cruise.
My virtual DE hull does not require "more cruise speed" but I'd prefer to put a "more efficient prop" on this build"
