Aronow Hydroplane

[Bobcat]

This from Facebook Fernando Arca.

So, Don Aronow didn't like when they canceled a race because the water was too rough, so he decided to build a boat to compete with the unlimited hydroplanes. Here's a quote from Don.
"''I love the rough water,'' Aronow said. ''There is a thrill about going out in water as rough as possible and racing. To me that was offshore racing. Now they call the races off if it's rough, and they race in lakes. If they want to go calm-water racing, let's go to unlimiteds. And that's what I'm doing.''
From what I read, Don Aronow and Gary Garbrecht came up with it, Gary designed it and Bill Seebold built it. It originally had 850 hp high reving Cosworth engines, it hit 175 mph according to Don, but it was sluggish in the turns. It was then upgraded to Keith Black Chryslers putting out 1,175 hp each, but I can't find much more information about this boat, how it ran, or even if it competed. If anyone out there knows more, let us know!

Aronow Introducing Unlimited Catamaran

For 17 years, Don Aronow has been the biggest kid on the block. And why not? It's his block, after all, the swampy stretch of 188th Street in Florida's North Miami Beach. With his fortune made in real estate, Aronow returned to the first love of his youth -fast boats. And he started on 188th Street by creating a Formula boat company.

Since then, Aronow has formed a string of high-performance boat companies - Donzi, Magnum, Cigarette and Squadron XII - all on the same block. No matter that he stopped racing offshore power boats 11 years ago after capturing two world and three national titles. Aronow's influence in the sport dominates. But now, the 53-year-old designer and builder has merged his Squadron boats with his recently reacquired Cigarette Racing Team, and he's preparing to invade new territory - the unlimited hydroplane circuit.

Aronow, in conjunction with Gary Garbrecht, the former head of Mercury Marine's racing program, has created an unlimited hydroplane that is revolution in design as well as power. Tests are scheduled to begin on Lake Havasu, in Arizona, this week with the craft, called the Aronow Unlimited, expected to make its debut on the thunderbolt circuit by the end of July. Buck Thornton, a tunnel boat driver from Richmond, VA., has been named the driver.

The unlimited hydroplanes are the fastest boats afloat. Riding on the tips of two sponsons and half a propeller, they are capable of reaching speeds over 200 miles an hour. Traditionally they are powered by a single, massive World War II airplane engine capable of generating 3,000-horsepower.

The Aronow Unlimited is the first unlimited of the catamaran design. It is considerably lighter than the traditional unlimiteds and is powered by two engines, supercharged Keith Black Chryslers producing 1,170-horsepower each, and connected to MerCruiser sterndrives. In test runs last year with smaller Cosworth engines, according to Aronow, the 30-foot-long craft reached 175 miles an hour on the straightaway but was sluggish on the turns. Now with the larger engines and the sterndrives, for greater low-end torque, the new craft is expected to roar around the ovals with a lap speed of 140 m.p.h. This would be fast enough to upset the unlimited establishment, because the fastest recorded lap is the 140.6 m.p.h. set by Bill Muncey in Atlas Van Lines last year.

To change from offshore powerboats to the unlimiteds, Aronow said, ''is like changing from Formula One to stockcar racing. And to master both is very difficult.'' Part of the impetus for the shift is that the deep V hull, which Aronow had developed to perfection in offshore competition, has reached its maximum potential.

''You can't grow anymore with the deep V because we're limited to the power we have,'' he explained. Instead, Aronow sees the offshore circuit evolving into two-boat teams, with a deep V craft used in rough water and a catamaran in calm water.

''I love the rough water,'' Aronow said. ''There is a thrill about going out in water as rough as possible and racing. To me that was offshore racing. Now they call the races off if it's rough, and they race in lakes. If they want to go calm-water racing, let's go to unlimiteds. And that's what I'm doing.''

For Aronow, who began racing Jersey speed skiffs as a teen-ager growing up on the New Jersey Shore, the challenge with the unlimiteds is to find new ways of adapting power to hull shape. As he points out, super-charged engines, sterndrives and catamaran designs have been around for quite a while, ''but no one has been able to put them together before and make it work.''

From 188th Street, production versions of the Cigarette race boats are shipped to kings and Presidents. Vice-Presidents, too. George Bush just had his re-powered. Owners include the rich and famous (such as Ringo Starr, Vitas Gerulaitis and H. Ross Perot) as well as drug smugglers. The sale of Cigarette T-shirts and jackets alone is bringing in $100,000 a year.

But for the biggest kid on the block, the fun isn't in the ledgers. It's on the race course. And that's where he's headed once more.

To add..... The failed success of the Aronow was the Mercruiser stern drives. We went through them like eating potato chips. Even though I was just a full-time crew on the Seebold craft, I always wondered why we didn't use the Arneson Surface Drive. We would have blown the doors off the competition with them mounted on the boat.

Hey! I remember the Aronow!! We were in Howard Arneson's shop installing the KB Hemi's. ( at the time I worked for Howard)... Howard allowed me to take a leave of absence to haul the Aronow to all the races. ( We went to Tri-Cities first).... I know that boat very well. ( I am trying to develop old negatives of the boat)

It appears he then converted it to outboards?

Go-Fast Blast From the Past: USA Racing Team, Quad outboards challenge the Unlimited status quo.
By Boating Staff



A rig of four big outboards is a common sight today but caused a sensation in 1983 when Don Aronow and Gary Garbrecht brought their USA Racing Team tunnel boat to the 1983 Unlimited Hydroplane World Championships on Clear Lake near Houston. The 30-foot boat was the first to apply tunnel-boat design to a hydroplane-scale hull, and the original hull, which was designed by Garbrecht, debuted in 1980 and reportedly weighed just 1,000 pounds. That boat was powered by a pair of Cosworth Indy car engines. In 1991, the New York Times reported on the continued effort of Aronow and Garbrecht to challenge the Unlimited status quo, with the boat now powered by a pair of 402 cid, 1,170 hp supercharged Keith Black Chrysler Hemi V-8 engines and MerCruiser sterndrives. The boat could hit 180 mph on the straights but bogged in corners. For 1983, the boat was reworked to accept four of the 450 hp Johnson V-8 racing outboards and entered as U-19 Don Aronow and Gary Garbrecht’s USA Racing Team. With tunnel-boat champion Jimbo McConnell in the cockpit, the boat placed second at the UIM World Championship at Houston to Milner Irvin in Miss Renault, a traditional hydro powered by a supercharged Allison engine. Of 18 boats entered, only three finished the final. The tunnel hull aired out beautifully and could hug the corners. See it in action in this video of the Houston UIM Heat, where McConnell won his first heat in U-19.

In 1980, the twin-Cosworth-powered ARONOW/HALTER SPECIAL (later known as ARONOW UNLIMITED) qualified for the Madison Regatta with a fast lap of 113 MPH. This was 12 MPH off the pace set by the Merlin-powered ATLAS VAN LINES.

The ARONOW was the first tunnel hull to appear in the Unlimited Class. It used a pair of Chryslers in 1981 and '82 but was plagued with mechanical difficulties. In 1983, it used four Johnson Outboard motors and placed second in the UIM World Championship Race at Houston, Texas.
