SPOKANE (Special) - Dave Heerensperger, owner of the Pacific Northwest's Pride of Pay 'n Pak unlimited hydroplane, said here today that his crew chief has completed the design of a revolutionary propeller which should add from 10 to 15 mph to the boat's assault on the world water speed record for one mile. The attempt will take place on Lake Guntersville, Alabama, May 19th.
“Jack Cochrane ordered three of these propellers, each with different degree of pitch. One will do the job, of that I'm sure," Heerensperger said. The propellers will be hand-forged in Italy to the specifications laid down by Cochrane and by Joe Mascari, internationally renowned propeller expert. Mascari expects to make a personal trip to Italy supervise completion of the wheels.
Heerensperger explained that the new propellers will be an improved version of the familiar "elephant ear" design now in use on several unlimiteds. "These elephant ears will look like they come from African elephants, they're so big," said Heerensperger. The particular design provides for much more blade surface than conventional propellers, with a corresponding increase in thrust potential and speed.
The Pay 'n Pak owner said propellers with 19.21 and 22 inches of pitch have been ordered. All will be 13 inches in diameter. "Slide rule calibrations indicate to us that the 22 inch propeller will be the one to use. After all, we're trying to break a record of 200.419 mph.
"I'd use the biggest wheel we can to get as much top speed as possible," the owner stated. He also revealed that Cochrane and Pay 'n Pak crew members have completed work on most of the 12 engines reserved for the record attempt.

Pride Has Weakness
Reprinted from The Daily Chronicle, August 26, 1969
SEATTLE (Special) - David Heerensperger, President of Pay 'n Pak Stores, Inc., announced here today that he has temporarily retired the trimaran Pride of Pay 'n Pak unlimited hydroplane due to a structural weakness discovered in the hull, and replace it with a new thunderboat purchased this week from Les Staudacher, Kawkawlin, Michigan builder.
The new hydro, which retains the name Pride of Pay 'n Pak, will also sport the team's Indian red, gold and black colors and U-25 racing number when it debuts in the APBA Gold Cup Race, September 28 at San Diego, California.
Tommy Fults, 1968 rookie-of-the-year in hydro racing, continues as the driver with Jack Cochrane crew chief, Heerensperger said.
"A thorough inspection of the present hull this week determined that one of the spars connecting the hull to the outrigger sponson has a severe head crack and must be replaced. Since there is not enough time to completely tear the hull down, fix and test it before the Gold Cup, I decided to temporarily retire the outrigger boat and buy a new racer, even if it's just for one race," Heerensperger stated.
The Pride of Pay 'n Pak outrigger hydroplane, a radical new development, did not realize its predicted potential on the hydro circuit this season. Its principal problem was one of dragging too much boat in the water. The crew made many modifications attempting to correct the fault. Nothing worked sufficiently, although all help alleviate it to a degree.

Pride of Pay 'n Pak
Reprinted from Sea and Pacific Motor Boat, July 1969
Dave Heerensperger's revolutionary new hydroplane has had a change of name, but her objective of breaking the world water speed record of 200.419.5 mph for a propeller-driven racer over a measured mile remains the same. Originally called Miss Eagle Electric as a sentimental link with Heerensperger's previous hydro, she is now officially named Pride of Pay 'N Pak after the 22-store group headed by Heerensperger. But she will still carry the Eagle's colors, number and fighting spirit.
Pay 'N Pak was scheduled to make her assault on the speed record at Lake Guntersville, Ala. May 19-24. The existing record was set in 1962 by Roy Duby, driving George Simon's Miss U.S. on the same lake.
Her unconventional design features outrigger sponsons jutting out from the main hull structure. At racing speeds, only these devices and the bottom blade of the propeller touch the water. Her engine is a Rolls Royce Merlin V-1620. Her propeller, designed by crew chief Jack Cochrane and propeller expert Joe Mascari, is almost its revolutionary as her hull design. The design provides for much more blade surface than conventional propellers, with it corresponding increase in thrust potential and speed.
Her driver, Tommy Fults, 1968 APBA unlimited Hydroplane rookie-of-the-year, described the boat its "fabulous". He said, " I don't seem to bog down in the turns with this boat. It hits a turn hot, sets up easy and moves around fast, all with it great feeling of ease and security."
Heerensperger summed up Pay 'N Pak this way: "We feel we have achieved the goal of all unlimited racers — speed with stability and safety."
