To each their own as we all value certain options, performance and our investment differently.
I've yet to hear anyone claim a quad 39 capable of 90mph. My guess is more like 85mph.
I would say the length, weight & CG of the 39 overcome the lift.
1050 h.p. behind a 34' boat trimmed up so that's allot of leverage coupled w/ the air trapped under the top in front of the windshield.
IMO 1200 h.p. or 150 h.p. more behind a 39' boat that weighs more doesn't have the ability to get the same lift.
I also don't believe the large top affects or contributes to the lift, it's the air that is stacked up under the top at the windscreen that causes the lift. The shape is the same regardless of whether you opt for standard or large top.
The large top is beneficial if you opt for 2nd row seating on a 39. Better wind / weather protection for more passengers.
We had 4 on board returning from the Bahamas in 4-5 footers w/ rain and whoever sat on the cooler behind the helm got drenched w/ the rain that rolls off the backside of the standard top.
