What's up Due???:D Hope the new project is going well. E

Yeah thats a cool pic, that boat is currently for sale, located in LOTTO I think.

Here's a link to the listing.

E Man-
Nice to hear from you!! The Project (like all of mine) is much greater than orginally anticipated, but we're moving forward (see Jaguar forum). The slowdown is because the composite shop is having the busiest "off season" they've ever had. So the Jag keeps being put on the side for more profitable work.
Say hi and let us see that CC when you're finished!!

My engines are going to the dyno this week.
(note the "special" 2" blower pulleys are for sale)

Hi Steve:

With that power the top speed potential is well over anything we planned back in the day....... Be careful.... but you knew that....and anything you are associated with is always first class and well thought out......just watch your speed... I'm not so concerned with lift as I am with dropping a sponson in a straight away and bow steering into a barrel roll.

Say hi to your dad....... he was one of the driving forces behind the Chris Cat project.

Wasn't "American Express" a Chris? Remember it well in "Big Seas 85"! Lots of air on that tape!
Sonny's Cat is a Chris and still running. There is another in the area as well. We had to change the bottoms to stop the porposing. There are also a couple of Shadows here.

Re: T2x
 

Yes, American Express....both of them...were Chris Cats. The first was Stu Hayim's...The second was Bob Molinari's...... two different boats.

Remember the words on the tape? "Don't lose her, don't lose her!"

Wow.......... Great memories ! Thank's Guys !!!!!!!!:cool:

T2X-
What causes a cat to "drop a sponson"?
Due

Due, powering thru a quartered sea and essentially riding on the stern of one of the sponsons, can load the opposite bow down into the water allowing the cat to 'push' on the radius of the hull and turn the boat.........That's why you have to be real careful with tunnel tabs, as they can accentuate a bow down landing, especially when you unexpectedly land in a hole. :eek:

Thanks for the explanation. I've never had the problem in my Chris Cat or Daytona.
Does the tunnel tab create more of a problem because it's uses a "down" position to help "load" the tunnel at higher speeds, whereas K planes are usually "up" at higher speeds?

My cat currently has K planes, but I was giving a tunnel tab some thought.

Due

Flash,

Are you running a tunnel tab? I remember T2x mentioning the tab reduced or eliminated the hop. Thanx for the pics by the way, great numbers too. I am glad you kept the arch.

Due,

Did you run a tunnel tab on your Chris?

rbtnt,

Saw the ad on the Chris at the lake, great looking boat with 525 Hawks I believe but a little pricey at $75K. There was one at the same broker 6 months earlier that was all white with 454's and 3's on the transom. The interior had completely been overhauled in white with a white dash and new white gauge package, they were asking $39k, sounds like a pretty good deal if the boat was dry and intact.

i have a tunnel tab on my 31 ao and i love it. but you have to respect it;)

T2X, Wasn't Smilin' JACKS < LIL" RHINO< BUSTIN" OUT< WD MARINE< ALL OF THEM CHRIS CATS"! THANX DB

I am not runing a tunnel tab, although I have thought about it. I think Spectre offers them as a standard item on the their 30' cat, so they cant be all that bad. I think you need the tunel tab more if running on a big lake where the flat water conditions are more likely to produce the hop, especially running high constant speeds for a period of time. If the lake gets rough enough to worry about droping a sponson, I should not be running at high speeds, as it would mean that there is to much traffic on the lake to be going that fast anyway. I would be reluctant to run a tunnel tab in the open ocean, under conditions where you would be more likely to stuff it. I really dont think that porpoising would be much of a factor in the ocean, because its just totally different conditions. Your in and out of the throttle so much, porpoising would not seem to be a big factor. This is just my opinion.

Whirly-
I've never used a tunnel tab, but my friend with Hot Pursuit has one. His tab is shorter than the latest iterations like Dana Marine's and the one Spectre uses. He was going to build one for my Chris, but then I sold the boat. He used modified K Planes.

Here are some chris cats

shadow?

Extractor
 

...is a Superboat Cat

:cool:

Post 72 is a 30 Shadow, "Love It"- I think

This is a Chris Cat. (1985)
It now belongs to Andy in the Midwest.
Due

wouldn't even just a wind gust at that speed be enough to blow over?

I think he's just a lucky "Cajun"!

Yes...with the possible exception of "Bustin' out"..... That one I'm drawing a blank on........

T2x

Bustin' Out
 

Not a race boat, it is privately owned by a guy in TX. Does Oil Field Equipment, hence "Bustin Out" is when a blow out occurs from a gas pocket- hairy stuff.

BIG set of monster motors 632 CI blown, etc. about 1000 hp on 92 octane, >1200 hp on Nitro- ? Speedy 3A's

Claims to have seen 140 mph on the latter. Wow

What was the max speed the hull was designed for ?

I still want one of these bad boys, I think the design was way ahead of it's time.

Re: Bustin' Out
 

WITHOUT a DOUBT! The Shadow and Chris Cats as well as the old Jesse James race boats were DECADES ahead in their design and function. Even with todays hot rides like in the 30 feet range, i.e. Skater, Spectre et. al. that extra weight those things had and their rough water handling I THINK are as good or better than todays lighter faster hulls. It is MY belief that although the fit and finish on todays boats is obviously far superior and the composite materials have helped to make them alot lighter and hence faster, one ride in one of those "old" boats will quickly convince you that they were truly designed to run FAST IN THE ROUGH!

Thanks GJL and T2x for your forward thinking design and invention.
