Dan Scott Taylor built his first submarine, Viperfish, in the late sixties. It took him four years to build while holding down a full-time job and without a single blueprint. "I just started building," he explains. "No designs. What didn't work I did again." The twenty-foot, five thousand-pound one-man vessel could make seven knots. He painted the outside yellow because yellow is "kind of the international underwater color." Though he had no plans for the boat, an article in the Atlanta Journal gave him the idea of joining with Dr. Roy Mackal, a professor at the University of Chicago and the American head of the Loch Ness Phenomena Investigation Bureau. After a short phone conversation, Dr. Mackal secured the sponsorship of Feild Enterprises, publishers of the World Book Encyclopedia. Their money sent Dan Taylor and Viperfish to the Loch Ness for six months in search of the mythic Monster. During one dive, the sub's hatch got caught on an after-dog and wouldn't shut. "There was a stream of water running down the back of my neck," Taylor says. "I rode that boat all the way down trying to shut that hatch, cussing and carrying on." Fortunately, Taylor eventually made a safe landing at the bottom of the loch, "which is good and soft." There he was able to shut the hatch, pump the water out, and make it back to the surface safely. Although at one point he had four moving contacts on his sonar screen, the sluggish Viperfish never did catch up with a Nessie (it was Taylor and Mackal's suspicion that many monsters, possibly sturgeon relatives, inhabited the loch). Taylor died in July, 2005 while working on Nessa, a forty two-foot sub that weighs thirty tons and can make twenty knots. He planned on taking Nessa to the Loch Ness for a return voyage. "You know, I just feel like I never did finish that job."
