Steaming at a cautious two knots, d'Iberville crept through the approach to the St. Lambert lock. Just astern came the icebreaker Montcalm, and after her four shoebox-shaped canalboats, veterans of the St. Lawrence's old 14-ft. waterways and sentimental favorites to head the procession of Canadian, American and foreign cargo carriers into the seaway...
...opening race of their climactic series, Mosbacher put Vim across the starting line ahead of Columbia -but to leeward. Shields merely tacked to get free air, and walked away from Vim to finish with the wide lead of 4 min. i sec. Next day, before the gun, Mosbacher got astern of Columbia as Shields maneuvered toward the starting line. Both boats were on the starboard tack (wind over the right side), and Shields was trapped. He could not come about onto the port tack to get to the line without violating Mosbacher's right of way under racing rules...
...opening gun. But many experts still like Columbia, and 51-year-old Skipper Cunningham, with an eye toward the bad weather that often roils New England waters in late September, feels that "heavy weather is Columbia's long suit." He admits his yacht is weakest with the wind astern but adds, "she's a bear cat to windward." And the saying goes that if a boat can go to windward better than the others, she does not have to do anything else. When polled, six experts who have seen all the races had some interesting observations...
...roll and yaw. The X-14 can hover indefinitely at any level, supported by the deflected thrust of its engines and balanced by its nozzles. When the pilot wants to fly horizontally, he merely adjusts the Venetian blind so that the gas stream from the engines shoots directly astern. Then the X-14 flies like an ordinary jet plane, supported by the lift of its wings and controlled by its conventional ailerons and tail surfaces...
...boundary layer control." After elaborate tests with models in wind tunnels, Northrop engineers fitted the wing "of an F94 jet fighter with a "glove" containing twelve slots running lengthwise along the wing. A suction pump driven from the main engine pulled air into the slots and pushed it out astern with the rest of the jet's gases, adding a little to the thrust. The reduction of drag was extraordinary, even when the power consumed by the pump was added as drag. A more advanced system with 69 slots worked even better...
