Turning in or out
Turning in (the starboard prop turning starboard) gives more bowlift, and is normally faster. However, turning in is more unstable than turning out. V hulls normally use turning in to get more bowlift, and cats turns out to add stability. Cats do not need bowlift either due to natural lift.
Only looking for some views here, since there are several P25's running twins out there.
