On Aug. 7 the fastest racing boats in the world will go whooshing across the surface of Lake Washington past a crooked, colorful line of some 800 pleasure boats tethered along the course (opposite) in pursuit of the biggest prize of the racing year—the Gold Cup. For five straight years the Cup has been won by Stanley Sayres of Seattle and his two flat-nosed hydroplanes, Slo-Mo-Shun IV and Slo-Mo-Shun V (next page).
To win again this year the Slo-Mos will have to outspeed a formidable list of invaders, including Guy Lombardo's brand-new Tempo VII, considered by some to be the sweetest boat this side of heaven. But the roughest competition of all may well come from another Seattle man, Ted Jones (see page 17), once Sayres's chief designer but now his most intense rival, who has conceived two new boats to beat the Slo-Mos.
Spouting rooster tails 30 feet high as they roar down the straightaway at 150 miles per hour, Stanley Sayres's Gold Cup champions "Slo Mo IV" (top) and "V" (right) lead Detroit challenger "Miss United States" around Lake Washington's 3¾-mile oval course
"Gale IV" nestles serenely in a Seattle rose garden after skidding out on the north turn and booming over the sea wall to intrude on a quiet lawn party given during the race by Dr. F. A. Black. Luckily no one was hurt, but "Gale IV" and Driver Bill Cantrell sat out rest of race.
