Same here it will lean in if you go fast enough.... Above 45-50...

Here is how it looks in mine. At about the 4 minute mark running 85-90 mph.

I think they were testing a new 30' Cat twin screw without interior at Lake Castake CA.
I did not find the answer but Drivers found one Motor & drive 15 feet from the boat and the Hull had a hole in the side. It was guessed at the time they were doing 80 mph when it happened. 4 of the 5 aboard Died.

Tunnel Hull

The Skater caught and passed the Apache with both boats running airborne contuously.

The old Cats in calm water/Vee's in rough water nonsense ended in the early 80's when we figured out that simple plywood was the wrong material to build cats ....or vees....out of. The next fable that needs debunking is that cats can't turn as quickly as vees. Attend one tunnel boat race and you will never utter those words again.

There are two problems with all of this however.....

1. The faster you go in any boat, the higher your skill level needs to be...aside from docking of course.

2. Not all Cats, nor vees for that matter, are created equal. There are any number of cats that I wouldn't be caught dead in....no pun intended. So to say that "Cat's can or can't do this or that." is a mistake. The fact that a Skater or Victory can do such and such is no guarantee that a "Hollywoodcraft" can do the same.

My first boat was a 16 foot Magnum Tunnel Hull that was raced by Stan Coburn. I found out on my own that you could do 70 mph and crank the wheel and be doing 70 mph the opposite direction 3 seconds later! I have never experienced this kind of excitement since. That was 1972, and a Senior in High School! At 70 mph only the last 12" of the Sponsons were in the water. It truly rode on Air and was the smoothest ride of all the Boats I have owned
Now 6 boats later and I look back. I was Nuts back then. I had that boat out of the water 2 different times at least 5 feet! I could of had a Blow over many times.
The Lord was my Co-Pilot I believe.
They Canceled My insurance and said it was a Race Boat, not a Pleasure Boat. That was 3 years after I bought it.

The rigger used engine mounting bolts that were too small is what I understand. One or more of them snapped.

Also, making the wrong move at "slow" speeds can cause a major incident. I have seen veteran racers flip boats at 1/2 the speed their boats are capable of. What happens to the guy with 1/10th of the experience in a similar situation.
There is no substitute for experience and also proper training from someone who knows what they are doing.

Aqua Mania in Key West is a good example of a low-speed barrelroll.

Depending on how many people are in the class, you can be paying less than $150 his travel. 4-8 hours???? Dude, 8 hours is the first day ALONE. Thats just classes by the way. Another hour or so traveling to your boat and doing pre-checks on your boat to make sure your equipments ready. Sounds like your going about this all wrong. You cant trust the guys pre-sets, his driving skills and yours are completly different. Also, no accredited boating course is going to help better your driving skills. Jesus, even the Coast Guard hired the boat school to teach them!!!:lolhit::party-smiley-004:


Wow, I just noticed that his thread is still going...! First, I have to travel a lot myself and if I and I alone have to pay for travel expenses ( At the time I thought it was myself, maybe one other person) from Florida to Tahoe and back including lodging and rentals - $1500 extra seemed reasonable. flights can easily be $400 - $500 each way.

Anyway, everything has changed. I signed up for the Havasu course on 4/25 and 4/26. Expenses are not to exceed $350. Still a whole lot of $$$ to pay for a safety course, but if it keeps me from doing the wrong thing the course is worth much, much more. Hey, most of us are still recovering from the economy taking a dump too. This was a difficult decision for me - not because of the value of the course, but because of having to spend this amount of $$$ on a sport...

Best decision you've ever made.

Rick

I would think the car is safer at the same slower speed, and at higher speed blowing over & hooking might be the big issues.
