Question on Duoprop moved from General Boating

Hello, I'm new to this forum so please excuse me if I'm not doing this correctly.
I posted this question on the General Boating section (please look) but now think that it is more appropriate here. I cut and pasted most of it below.

I'm hoping someone can explain to me the difference in planing characteristics, if there is any, of a boat using a VP Duoprop vs that of a single prop; all things being equal other than the drive.
I have been told that a boat with a DP planes at a slower speed and at a more pronounced "bow down" attitude or that the stern is less prone to "digging a hole". Help me to understand this. If two boats are going the same speed (SOG)and everything is the same other than the outdrive, then is there really any difference in the "angle of attack" (for lack of better words) of the two boats, and aren't they both planing equally?
Wow, I know this sounds stupid but I won't rest till I understand!!


Thanks in advance for sharing your knowledge and experience.

Ayuh,.......

A dual propped outdrive creates More Stern Lift,........
Hence,.... It'll be Planing Sooner......
