Douglas N. Privitt

Douglas N. Privitt was born in Inglewood, CA in 1931.  He grew up in rural Missouri, near the town of Osgood, on his parents’ farm.  He was an entrepreneur from an early age and pursued his entrepreneural dreams all his life. One if his first, was to build a glider to fly down the hill in front of his parents’ house (unknown if it ever was completed or successfully launched).

He graduated from High School in ~1949. He achieved a high school education and never went to college.
(no one in the Privitt family had ever gone to college before, they were all farmers.)

Doug's first business was a machine shop and welding shop, which was next door to the gas station on the main road into Osgood, Mo. off Route 139. The building and lot (Lot 4 in Block 1) was sold to him for $500 on April 3, 1952 from his parents Clarence and Oma.

He partnered with the gas station owner next door to start J&P Oil Company (Johnson and Privitt) which was also a Junkyard.


The building by the telephone pole was the gas station (with the Coca Cola sign).


The Junkyard out back

Doug decided to try to find coal on his fathers farm (his father owned the mineral rights). So, with Donald Ray Woody (Jaunita's younger brother), they built a drilling derrick and drilled for coal. They did not find any. Coal deposits have been found in various locations throughout Missouri, so it was possible they could have found some.


The derrick by the barn on Clarence and Oma's farm. (that is Donald on top of the derrick).

His next business was a radio repair shop (in a shed next to his home in Osgood). It's unknown if he also fixed TVs. Later after he moved to California, as a side job he fixed B&W tube televisions at Swifty's TV Repair in Compton, near the Compton airport where he kept his Bellanca airplane.

He moved to Inglewood, CA in 1956.

He worked as a tool and die maker at Research Tool and Die in Gardena, CA and eventually became the shop foreman. Research Tool & Die Works (RT&D) was founded in 1944 as a tool and die job shop. (That is Doug’s 1957 Ford Ranchero in front of the building).

Motorcycle Racing

He was also a winning scrambles racer (now Motocross) riding a 1957 Bartali 125cc 2T motorcycle purchased new, still in the crate and needed to be assembled.  He still has part of the original crate in his garage.  The motorcycle club he was a member of was called “Bogus”.  Other members were Keith Stack, Don Schue, Wayne Kinny, and Donny Thompson.  He raced for a number of years and finally quit after being run over by one of his own Bogus club members (we believe it was Keith Stack).

Submarine Designer

Doug Privitt has designed and built submersibles for more than 70 years. His “Submaray”, “Nekton” and “Delta” submersibles have logged over 12,000 dives off 5 continents and 30 countries. Doug began his submarine career in Torrance, California in the 1950s.

Keith Stack, a fellow motorcycle racer, introduced Doug to Ed Armstrong, who had built a one-man sub, “Explorer” (one conning tower). Doug became interested in submarines and started working with Ed.


|The "Explorer"

Doug helped Ed build a second single person sub called “Aqua-SUB” (one conning tower) in 1959.

Next were the "Sportsman DRY Subs” (which had two conning towers) in the early 1960s. The Sportsman actually went into production at the Armstrong-Blevans Sportsman Dry Submarine, Co., Inc. It's unknown how many were actually built, but we believe it was about ten. The cost was $3,600.

"Sportsman DRY Sub" Brochure

September 1962 Mechanix Illustrated, Fun with "Sports Cars of the Deep" p. 55

After working with Ed on several versions of his submarines he decided to build his own two-man submersible. Construction started in the back of Research Tool & Die Works where he worked as a die maker and shop foreman. Every submarine that Doug built always started as a cardboard mock-up to see how it “felt”; was it comfortable; did it provided good viewing, etc.

"Dolphin"

1958 the “Dolphin” cardboard mock-up and parts under construction, the white conning tower is the forward hull from Ed Armstrong's “Explorer”.

The “Aquasub” and “Sportsman” subs placed their ballast tanks of the side of the sub, this was a little unstable, but workable if you were cautious. Initially the ballast tanks were tacked in place on the side of his new sub as well, but Doug changed his mind and decided to put them on the front and back.  By having a greater separation, he theorized that it would make the sub more stable. This started a dispute between Ed and Doug and the two separated and stopped their submarine building collaboration.

At 14 feet long and 3,200 lbs., it could dive to a maximum depth of 350 feet. The “Dolphin” was sold to Martin Toggweiler who changed its name to “Submaray”.  It was a play on words and was named after Mart’s boat the Maray.

Does anyone know where to find online this episode of The Wackiest Ship in the Army?

The last known picture of the Submaray. It is unknown where it is now located, somewhere on the East coast.
( The water looks very murkey on the lake and they were likely not able to see the bottom from any of the ports)

Submaray was last reported to be in Vancouver, Canada. While welding on the hull's battery box the hull was warped. We suspect this could be repaired, but the status is unknown.

Airplanes

Doug's first airplane was a Bellanca which he co-owned with Dave Walker and tied down at the Compton Airport.
The Bellanca 14-7 Cruisair and its successors were a family of single-engined light aircraft manufactured in the United States from the mid-1930s onwards.

"Nekton"

“Nekton” refers to the actively swimming aquatic organisms in a body of water. It was called Nekton because a submarine is free swimming.
In the mid 1960s, a group of geologists from southern California who had been using the Submaray, asked Doug to build a two-man submersible for them that could dive to a depth of 1,000 feet.


Jim Vernon, a geologist, in the “Submaray”

At the time Doug was currently working at C & D Tool & Mfg. which was a machine shop and a partnership with his nephew Craig DeWeese.  The geologist group created General Oceanographics and hired Doug as the VP of Engineering and financed the project to begin construction.

Again “Nekton” started with a cardboard mockup
 
 

Doug and Craig with the help of Jim Vernon, the president of General Oceanographics, designed and built “Nekton”. 

Model testing to verify its capability to dive to 1000 ft.

The innovations besides the increased depth (1000 ft.) included more ports and a small conning tower for the observer. The observer conning tower did not work very well (your breath caused the ports to fog up).

In 1968, it was tested to 1,500 feet (it just fit in the chamber) at the US Navy engineering facility in Port Hueneme.

1969 Santa Barbara Oil Spill
On January 28, 1969, a blowout on an offshore oil drilling rig 6 miles off the coast of Santa Barbara led to the release of over 4 million gallons of crude oil into the Pacific Ocean.  The source of the spill was a blow-out on Union Oil's Platform A in the Dos Cuadras Offshore Oil Field.  The spill ultimately spread across 800 square miles, creating a 35-mile-long slick and coating some 100 miles of mainland California and Santa Barbara Channel Islands coastlines in a black, viscous goo. “Nekton” was used to see the actual blow out’s location and estimate the seep rate.

Rescue of the Deep Quest, October 7, 1969

The GSF Explorer, formerly USNS Hughes Glomar Explorer (T-AG-193), was a deep-sea drillship platform built for Project Azorian, the secret 1974 effort by the United States Central Intelligence Agency's Special Activities Division to recover the Soviet submarine K-129. The Deep Quest was placing cement cylinders on the bottom for the Glomar Explorer to practice picking them up (to simulate and practice picking up the Soviet submarine). There were polypropylene lines (which float) attached to the cylinders and the Deep Quest "ran over one" snarling the line in its propeller, essentially tying it to the bottom with a heavy cement weight. The Deep Quest could have surfaced, but with the cylinder attached to its stern it would have come up vertical and created a very uncomfortable orientation for the crew. They decided to call for help. There is an implicit agreement between all submariners that if you get a call, you will drop whatever you are doing and immediately go assist with the rescue.

Following "Nekton's" success, Doug built two additional submarines “Nekton Beta” and “Nekton Gamma” for General Oceanographics that were launched in 1970 and 1971 respectively. With now three submarines they renamed the original “Nekton” to “Nekton Alpha”. 

The difference between Alpha and Beta/Gamma was the forward conning tower was removed and replaced with forward looking ports inside the ballast tank. The basic hull design was unchanged and the all were capable of diving to 1000 ft.

At the Isthmus of Catalina Island, off of Bird Rock, is a sailing ship wreck in over 200 ft. of water. Several artifacts, including many portholes, were recovered from the wreck. This is the wreck from the 1935 movie the Mutiny on the Bounty. The Bounty replica was burned and sunk as part of the movie.

Mutiny on the Bounty (1935) - IMDb Actor James Cagney was sailing his boat off of Catalina Island, California, and passed the area where the film's crew was shooting aboard the Bounty replica. 


Artifacts from the sailing ship wreck, from the 1935 movie Mutiny on the Bounty.

Most of the wood from the wreck is now gone and it is mostly a large pile of ballast, with some artifacts. To generate business General Oceanographics would give demonstration dives for clients at the Isthmus of Catalina Island. Doug found an old trunk lid at the swap meet and decided to build a "Treasure Chest" and planted it on the wreck. During the client dives they would casually drive past the planted treasure chest. The client would see it and exclaim "Stop" but they just continued on past. Then they would tell them that they had been had. The tell tale sign was the rope handle that would have been disintegrated long ago.

"Nekton Alpha" current condition

When General Oceanographics was dissolved, Nekton Alpha was sold. It was renamed the SeaHorse, and used for a number of years to inspect the intake and outfall tunnel of a nuclear plant in New York. They installed the guard rails, wheels and extra thrusters, presumably to protect against bumping and rubbing against the outfall tunnel in dirty water.

This is the last known picture of "Nekton Alpha"
It was up for bid on eBay in Worcester, MA on October, 7, 2006, but did not sell because the reserve was not met. The last bid was for $100,100.

It's currently in a wreckers yard in New Hampshire, owners and location unknown.

"Nekton Beta" current condition
The location and owner of "Nekton Beta" is unknown. It is suspected it was destroyed and sold as scrap metal.

"Nekton Gamma" current condition


“Nekton Gamma” as it is today.

Hank Pronk restored and made several “improvements” to “Nekton Gamma”.  The forward and rear ballast tanks were removed and placed on the sides.  A spherical port was added at the front (spherical ports have significant distortion compared to a flat port). An escape pod was added, and two vertical thrusters were added to provide depth control/keeping.  It was sold and is now somewhere in the San Francisco Bay area.

“Hang Gliding”

Doug found an ad in the back of a Popular Science magazine for plans for a “Hang Loose” glider that cost $3.00.  He sent in his money and received the plans.  Doug contacted Jack Lambie and he gave us directions to where his crashed Hang Loose was located (behind an office building off La Paz Road in Irvine, Ca.).  We went there to take a look at the original hang glider.



Doug and Ken built their version with some modifications: we used pine strips for the ribs instead of bamboo that was indicated and included a wedge to create more or an airfoil and hopefully give it better lift and started building.  Doug received a call that there was going to be a gliding meet in Irvine, CA. so we finished up our glider and tested in the street in front of our house.  We pushed it along and it would generate enough lift to get the pilot off the ground.  So,  with little to no experience flying it , we packed it up and took it to the meet.  We named ours the “Swing Low”. When we got there we found out it was the " Otto Lilienthal Universal Hang Glider Championships".

1971 Universal Hang Glider Championships at Irvine, California

Hang Gliding History article,


Every flight resulted in a crash, which were sometimes severe.  So, we would just take it back down the hill, patched it up, waited for the glue to dry, and took it back up to the top of the hill for the next short flight.


Our last flight of the day, and as usual, resulted in a crash.

1972 Manned Powered Airplane based on the “Hang Loose” design with tricycle undercarriage and propeller, Gardena, California


The propeller was hand made.

We used the 1962 Puffin propeller design as the basis of our propeller, but we adjusted the diameter to fit our plane. From the Puffin propeller we had the angles and thickness at various distances. We made our propeller using a hand saw, disk sander and jig to hold and measure it. We used the jig to measure each stations angle and thickness, if it was off we sawed/carved off some wood to eventually make it a rectangle with the proper angle and thickness. We blended it between the stations. Once we had the proper twist, we marked it at 1/3 and hand cut the airfoil shape using the disk sander.

“Delta”

It took approximately six years for Doug and his son Kenneth Privitt to design and build the “Delta” submersible at MARFAB in Santa Ana, California.  Design started in 1976 while Ken was in the BS Engineering program at UCLA and was launched in December 1982. Ken used a General Automation Spec-16 computer which he built with the help of Greg Atkins and Mel Jones of A.J Computer, located at Langford Machinery a few doors down.  The computer had 16K of core memory and the calculations were programmed using the Fortran programming language under the General Automation DBOS (Disk-Based Operating System). Since the design calculations were the last thing we ran on the computer, the program is still in the core memory card, which Ken saved as a memento.  We called this submarine “Delta” because we could not use “Nekton”, it was owned by General Oceanographics.  So we just used “Delta” to continue the prior “Nekton” numbering sequence (Alpha, Beta, Gamma).

The sole proprietorship company that Doug and Ken made a living from was called MARFAB, short for Marine Fabrication.   We worked during the day refurbishing machine tools for sale at Langford Machinery and at night (after 5:00 when Langford Machinery closed) we worked on "Delta", sometimes until late in the evening.  One evening we worked until about 2:00am, we had started welding one of the main battery box seams and once we started, we had to complete it while it was still hot.

The Logo was designed by Robert Kingston when he was living in Venice, California.  The name is under the waves to indicate the company’s under water capabilities.
Construction on “Delta” began around 1976.

The structural design, port design, electrical system, life support system, motor and propeller design was done by Ken using his engineering knowledge gained as a graduate (BS/MS) of UCLA's School of Engineering. Doug and Ken constructed most of “Delta's” supporting equipment including the underwater communications and tracking systems, transducers, the mechanical and hydraulic arms, the submersible lights and the camera housings.  Delta included an additional right-side port and a center forward looking port for the observer in the forward ballast tank. A total of 19 ports, which provided excellent visibility, better than all the previous subs. "Delta's" targeted depth was increased to 1320 ft of sea water (1/4 mile). It can go deeper in fresh water. This depth was selected because 1/4 mile covers 80% of the Conintental Shelf and would provide a sufficient number of clients that would be interested in leasing the sub.

Submarine Design - How to design a submarine

Grounded vs. Ungrounded Electrical Systems for Use in Manned Submersibles - Marine Technology Society Journal, Fourth Quarter 1981 Vol. 15 - No. 4 

Several scale models were made and tested to destruction to verify the calculated design depth.  It was somewhat with a heavy heart when we put them into the pressure chamber to crush them, since one had taken us over two months to make, within 0.001” tolerance on the dimensions (as close as we could make/measure it).


Crush depth of each model (respectively):
2793 ft.               2838 ft.
2763 ft.               3086 ft.
2882 ft.               2725 ft.
3041 ft.               3625 ft.



The internal rings were made as a “T”, to increase their stiffness and to decrease their weight.

“Delta” cardboard/sheet steel mockup. Every sub started with a mockup.



Construction progress in 1980.

We placed .100 deep holes all along the bottom plate of the Battery Box (the holes in the red spots). The plate was made .125” thicker to compensate for this.  These would be used in the future to measure how much wear occurred as the sub was moved about and the plate would wear with the friction across the floor.

"Delta" Testing and Launch

“Delta” was tested at the Navy Hydrostatic Test Chamber, Port Hueneme California (the same facility where the “Nekton”s were tested)



We designed “Delta” it to just fit into the 72” diameter pressure chamber with about 3” clearance (without the hatch, it wouldn’t fit with it in place, we tested it separately).  Delta was completely filled with water and a hose connected to the outside of the chamber.  When external pressure is applied and the pressure vessel is compressed, water (which is incompressible) would be extruded out the hose.  We plotted the applied pressure against the water displacement. It would be linear until the metal started to yield (bend and move) and the graph would begin to bend down, indicating that the material was actually yielding.  This was not something we wanted since it could damage the sub and all the work we had put into it. So, to prevent this the sub was filled with water to prevent it from collapsing. Also. since we only tested to 1.5 times the rated depth, we never came close to yield and the graph was always straight line and “Delta” was never in danger of any damage.

“Delta” was completed and tested shortly before Christmas 1982.



“Delta” was launched in Redondo Beach Harbor on December 21, 1982. 


"Delta" ready to launch

Three attempts were made to get “Delta” submerged.  1) For the first attempt the calculated correct amount of lead weights, Weight and Displacement calculations, was loaded (additional lead was brought, just in case), but approximately ¾ of the Conning Tower was still out of the water with both ballast tanks empty.  2) The volume and displacement weight of ¾ of the conning tower was estimated and all the available lead was put in, but approximately 10” of the Conning tower was still above the surface.  3) With no additional lead to use, the steel jack from the Dunkle Brothers Machinery Movers truck was put in, Delta finally went below the surface to a depth of 15 ft.  The dive lasted 15 minutes.

The defination of a submarine: the weight of the submarine must exactly offset (equal) the weight of the water displaced.
If it is less, it is a boat and will float on the top of the water (and cannot sink).
If it is more, it is an anchor and will sink to the bottom.
If it is equal (Goldilocks, Just Right), it can freely glide up or down in the water and will stay put when stopped (not drift up or go down).

In operation we target the sub to be about 50 pounds negative, so it will sink but still be close to neutral bouyancy. When the pilots and observers are swapped out after a dive they must be weighed and the difference in weight be brought in ( lead bars) or taken out of the sub.

The first and second try for the first dive.

The first “real” dive was 140 ft. at the Isthmus of Catalina Island.  Doug and Ken ran a check of all the systems, and everything worked perfectly.  As we were moving along, I exclaimed “there is a large lobster”, Doug said use the arm and try to catch it.  I carefully moved the arm behind the lobsters’ head (this is the best place to catch them, which I learned from snorkeling and catching them by hand) but I slightly bumped the lobster as I was trying to grab it, and it “squirted” away.  I said, Damn I missed it, and Doug said that’s OK, there are plenty of them, so we traded places and Doug (who had caught lobsters with the Nekton’s arm) picked the biggest one and caught a 5 lb. Lobster.  That day we caught four lobsters and one abalone, which we ate for dinner that night.

“Delta” is 15 1/2 feet long, weighs 4,800 lbs, and can dive to a maximum depth of 1,200 feet (this was reduced from 1320 by the ABS because of a temperature dependancy of the steel). “Delta” has logged over 6,700 dives worldwide, with no dive days lost except to bad weather, and has a perfect safety record.

The S.S. Brother Jonathan was a steam paddle wheeler that set sail from San Francisco to Anchorage, AK on July 28, 1865. It struck an uncharted rock (now called Brother Jonathan Rock) near Point St. George, off the coast of Crescent City, CA, on July 30, 1865. The ship was carrying 244 passengers and crew, with a large shipment of gold. Only 19 people survived, making it the deadliest shipwreck on the Pacific Coast of the United States. Based on the passenger and crew list, 225 people are believed to have died. It was carrying: the annual treaty payments in gold for Indian tribes, Wells Fargo shipments consigned for Portland and Vancouver, U.S. Army payroll, and gold carried on board by the passengers.  The gold alone (not the rare coin value) is valued at $50 million in today's dollars.

1993 Brother Jonathan Discovery
On October 1, 1993 the Brother Jonathan was discovered off Crescent City, CA by Don Sieverts in the submarine Snooper near Crescent City, CA.

1996 Brother Jonathan Treasure Discovery
On August 30, 1996, "Delta" found 875 gold coins from the 1860s in near-mint condition. Over time, the salvors recovered 1,207 gold coins, primarily $20 double eagles.

Notice it took three years to obtain the salvage rights.

Gold Recovered from the Brother Jonathan:
These coins were sold at auction for approximately $2,000,000.  

One of the $10 Gold Eagles sold at auction for $100,000.

Doug and Don Sieverts with their subs

This bag contains 564 coins (all Double Eagles, $20 gold pieces).
That is Doug Privitt's hand holding the first recovered treasure, which is worth approximately $2.8M.
The coins were MS 65, MS 66 and MS 67 (MS = Mint State)
In fact they were all essentially just made, they were still in the original oil-paper rolls and had never been circulated.


They recovered the Purser's safe.
They had visions of opening it on the Geraldo Rivera Show (TV Series 1997-1998), like he did live for the Al Capone vault.
They had hoped it would contain $5M in gold coins, but it only contained a wool blanket, one coat, and a purser's hammer.

After the discovery, Deep Sea Reasearch (DSR) went to Federal court to obtain salvage rights for the Brother Jonathan.. This started a long legal battle with the State of California. Resulting in seven consecutive rulings against the State of California: the Federal District Court (three times), the Ninth Court of Appeals (twice, 2-0 and 3-0), and the US Supreme Court (twice both 9-0).

Settlement with the State of California on the Brother Jonathan

It is ironic that after considerable expense on both sides that the settlement with the State of California was for 20% of the gold coins that were found. This was less than what DSR had been originally offered to settle with the State of California and begin the salvage. Multiple millions of dollars in legal fees were needlessly wasted..

In total 1207 coins were recovered, 200 went to the State of California, 1006 sold at auction for over $4,000,000 and one was donated to the Del Norte museum.

The encrusted $10 Gold Eagle in the lower right corner has been donated for display at to the Del Norte Museum in Cresent City, CA. The museum contains many of the artifacts recovered from the Brother Jonathan.

Cars

Doug bought this 1957 Ford Ranchero brand new and has owned it ever since.
He has restored it twice, the second time in 2017, it still runs and is in excellent condition.

Bicycles/Tricycles/Walking Machine

A project that was started but never finished was a walking machine. Doug started it in approximately 1965 while at General Oceanographics and was a pile of various parts in a box. He never figured out the mechanism to go from a pedal and chain to moving legs, there were going to be six of them. It was sold with the Marfab shop contents.


This is our Chopper bicycle that was built in approximately 1968


This is the tricycle that we built and considered going into production with.

His second airplane was a Cessna 182 which he co-owned with Kurt Bourhenne.


(Doug's Cessna, at the Cameron Park airport, Ca.)

He was building his own airplane, a 1/20 scale replica of a B-17 Flying Fortress Bomber.

This was a 1/20 scale model of a B-17 that Doug built and intended to fly. The cockpit was just big enough for him to sit in and with a battery, motors and propellers he expected to be able to take off and fly. It was never completed and was sold with the Marfab shop contents.

Another project was a single place Scorpion I Helicopter that he built. He purchased the plans in the 1960's and always intended to build it, but it took him over 50 years till it was finally completed. He took several years of Helicopter flying lessons until he could actually fly one, he said that they were tricky. When his Scorpion I was completed, he started it up outside his shop, took off and hovered to about 3 feet off the ground, then landed and shut it down. The engine had a coolant problem and was overheating. It never flew again and was sold with the Marfab shop contents.

Doug was always very "Thrifty"

Doug would never throw anything away. He would rather fix something than discard the old one and buy a new one. He would say "there is still a lot of life left in this." For example his regular car was a Honda Civic (again purchased new) that he drove till it almost died, then restored it and continued to drive it for many years, it became a classic. He finally got rid of it when Jaunita passed away and he started driving her Honda Accord, he no longer needed the Civic so he finally sold it.

Doug would dumpster dive at his shop and pick out the "good" things his neighbors were throwing away. He took any metal he could find and would sell it for scrap, he actually made some money. He would keep nuts and bolts, motors, parts, metal, fittings, tools, electronics, etc. anything that was "still good" and that he might find a need for in a future project. The only things he threw away were things that could not be scrapped and couldn't be potentially repaired.

He once found a battery powered wall clock that didn't work. He took it apart and put in a second battery to double the voltage to the motor and it started working. He put it up on the wall in his shop so he could see what time it was. Doug had enough parts and supplies in the storage area in his shop to work on almost anything and a lot of that he found in the dumpster. Even his shop neighbors would drop off their discards in front of his shop so he wouldn't have to dumpster dive.
