I don't think that Progression was popped from any other boat. Their hull configuration is pretty unique. Looking at the transom reveals a 24, 23, and a 22 degree progressive deadrise from keel to chine with the strakes being the seperation points.

Body Shot--- Don't know much about Inferno, except that it has quite a few years on it, Richie Sutphen would be a better choice for info.
Phantoms -- definitely original designs, and I like the little canopied "A" boats. They are the only racing vees that make any sense to me....very entertaining...identifiable as race boats and not "runabouts with numbers on the side"....and somewhat safer than open cockpit , stand up designs.
Bulldog---There are idiots driving vees and cats ,true, but that does'nt mean that some products and designs are not better than others. You are wrong regarding me not liking anything I have not driven or owned. I dislike a lot of boats I have driven ....On the other hand call me crazy, but I don't buy anything I don't like.....do you? For instance I don't own 40 year old big blocks..... I use 3 year old design 2.5 liter race outboards.
Twin 29--- I'm grateful you don't dislike me.
Now I can sleep nights. One other thing..... I recall using "penile substitute" in my post( what else do you call a fifty foot long, eight foot wide, pointy object with a too much horsepower)...but "moronic" is eluding me?????? also, I too have run in the 1000 Island Poker Run.... as a passenger.... until I was pressed into service to recover an outboard Velocity that had been so badly mistrimmed and handled that it broke the pelvis of the owner's wife and gave him a concussion.... after hitting an ore boat wake at full throttle. Come to think of it...there's an opportunity to use the word "moronic". Finally, while 70-80-90 is in fact Vee bottom speed..... Cat's cruise there.... Vees don't.
Screamin-- Cobra designer Jean Claude Simon, Cigarette designer (originally a 32' Cary called "The Cigarette" by the ubiquitous Don Aronow) Harry Schoell. The Cobra had/has a deeper Vee especially forward.... as I recall 2 degrees more deadrise.
Now please no more hull trivia... I was out all weekend in my Skater (my son even throttled for a while... look out Joey , he's coming)...on Barnegat bay....and I am verrry content.

This was posted by T2x on the cat thread and I thought it really belonged here......
====================

Ron P.--My thoughts on "spinning" in..... Simple physics.... Right hand rotation propellers,torque (lean) the boat to the left. Left hand rotation propellers torque the boat to the right. In a twin engine boat spinning outboard or , RH on right side, LH on left, the torque of the propellers tends to return the boat to level when one side or the other leans outward. When props are spun inboard RH on left, LH on right, or counter rotated the torque tends to make the lean worse. This occurs because as a boat(Cat or Vee) leans to one side, the prop on that side buries deeper and exerts more force, while the prop on the other side rises (in some cases out of the water) and exerts less force. So...... If a RH prop is spinning on the right side of a boat leaning to the right, the prop tends to push the hull back over to the left. (spinning Outboard). If, however, the left hand prop is on the right side in a right hand lean , the prop tends to continue to roll the boat over. I submit that this is why there has been such a dramatic increase in barrel rolls (even in straight-aways) in races in recent years. When I flew over races for 16 years, I could always spot the counter rotated boats, because they behaved very differently (and definitely not better)than their properly spun (outboard rotation) competitors.
The reason that many people spin them "backwards" is the fact that on some hulls the boat may gain a mile or two per hour at top speed....or..... the boat has a bottom tune that needs more bow lift. The speed can generally be achieved in other ways without using an unnatural rotation as a "bandaid" (This is particularly problematical on stepped bottom boats that skid first, then catch suddenly, then roll outward......get the picture?)
One can re-tune most bottoms to add rocker to provide bow lift without resorting to ill advised prop rotation changes.
Counter rotation is adviseable on SINGLE engine race boats when the courses change from counter-clockwise to clockwise. LH props like right turns and handle better, RH props like left turns. Since the Bravo drive allows for a simple flick of a lever to reverse rotation, one would expect that Factory 1 racers would have a supply of left and right props depending on the course ....... up until this year most F1 racers don't...... I guess nobody has "invented" this yet.
It's T2x....NOT "Tx2" please

OK, since I have everyone gathered in a couple of places 
, how about addressing the impact, or lack of impact, from abroad. That could mean both from the fairer sex as well as from Europe, Asia, etc.
Do we, in NA, have a corner on the market for this quest for speed over the bumps. Notice the "over the bumps," because there are much faster floating devices out there than offshore boats. Does the world speed record still belong to an Englishman, didn't a couple of people get to 300 mph in some rocket on water?

WHAOOOOHHH!!! Take it is easy... T2x has brought some of us some valid information no matter what he owns...Besides, most of us all started out in a Vee-Bottom, I'm sure he did too. Yes, I run in 4-6,and someday I may retire my boat to be a jacuzzi. The boat never sees a lake, only the Atlantic Ocean or BARNEY BAY. It just doesn't matter what you run, we are all here to learn a little and have some FUN!!!
