One of the reasons the GT20 {probably} gets flighty would be the flared bow farther forward than the less flared bow of the V21. The V21 also has a more raked shape down the chines. At the Stern the V21 is more flared out from the keel line with a more straight edge to the rub rail. That in combination with the more swept back profile helps the V21 to fly at a higher speed with a more aerodynamic shape than the GT20. The GT 20,s big frontal area though would help her to fly at a reasonable High speed with less power isn't really the shape of choice for really high speeds like above 100mph. Also the stern area of the GT 20 were the flare from the keel to the rub rail comes out is more rounded. This looks nice and has some flying function but not as aerodynamically efficient as a wider flare and straighter edges. The best example on any Vee Bottom boat made today is the Allison RR. Very small very swept back frontal area, super wide wing flared stern ,shallow free board light and super fast. 120+++MPH. Basically a stealth wing with an outboard on the back! lol https://s-media-cache-ak0.pinimg.com...2ef957edb9.jpg
That all makes perfectly good sense, especially the part about being designed to go fast (lots of lift) with less horsepower. There weren't many motors back in the mid to late 70's that could even push that boat to 100, so it makes sense they wouldn't be designed with that in mind. The XR2002 that replaced it took care of that issue when higher horsepower motors were available. Like I said, I've always liked the way the Triad looks.Quote:

Merc V6's had been out for a little over a year when the first GT20 arrived, but Paul may well have designed it around the inline 6. Don't think it was truly designed as a race boat though. I have an article around someplace to that effect.
That blue RR is a pretty boat.I just can't fit in it!
The XR2002 was introduced in 83 so I'd guess the design phase was '82-'83, well before the V21. The XR is faster than either the V21 or especially the GSQuote:

I always wondered why there was never a sport/race boat version of the XTB21, especially given there was the XB2002 and XR2002 which shared the same hull. The XTB21 was definitely capable of triple digit speeds.
The XR2002 and XB2002 aren't the same hull
I always thought they were. Had a XR2002 and have driven a XB2002. What's the difference in the hull?Quote:

Interesting. I just always assumed it was the same hull with a different cap as I never measured them. Would have thought the narrower pad would have been on the XR.Quote:

I've still found myself drooling over the new ones, but I figure I'll keep my GT forever... or until the new, super secret model is about 10 years old! LOL
A couple of shots of my XR.

That's the boat I originally wanted.
