![]() He also designed a pressure hull that remains watertight as the rest of the model fills with water. A solenoid valve vents air out and allows the sub to dive a second solenoid valve releases propellant from a copper holding reservoir and allows the model to surface. He designed and built a ballast system to allow the model to submerge and surface. “The entire project was a true engineering challenge,” Ryder said. Foster and others at WHOI provided enough info for Ryder to start building the model of Alvin as it looked in the late 1970s when Foster had piloted it. He correspondended with Dudley Foster, who retired in 2006 after a 32-year career as an Alvin pilot. He needed detailed descriptions of the sub, so naturally he turned to Woods Hole Oceanographic Institution (WHOI), which has operated Alvin since it came on line in 1964. “As a diver for many years, I have always had an interest in underwater vehicles,” he said, “and I have followed Alvin’s exploits since I was young.”Īt his home in Western Springs, Ill., Ryder, then 62 years old, set out to build a 1/8-scale fully operational model of the 23-foot-long Alvin. He decided to make a one-of-a-kind model of a one-of-a-kind vehicle: Alvin, the iconic research submarine whose 50-year resume includes some of the greatest discoveries in and about the deep sea. So before he retired in 2005, he looked for a project that would not only “keep me out of my wife Marcy’s hair,” as he put it, but also give him something he could really sink his hands, heart, and mind into. Ryder is also one of those hands-on guys who enjoys building model boats-radio-controlled ones with lots of details and moving parts. His experience ranged from searching for murder weapons on the bottoms of lakes to collecting specimens for the Shedd Aquarium in Chicago.
