A former saloon car racer and Dutch Formula Ford champion, and a protege of Toine Hezemans, Boy raced the ex-James Hunt March 731 in F5000 in 1975 without realising much by way of results, and thus switched to Formula 3 in 1976, a year which saw him make a promising GP debut at Zandvoort.

    With backing from his loyal sponsors, Hayje secured a seat in the RAM March team for 1977, a move which was to prove disastrous for all concerned, the Dutchman departing abruptly following his non-qualification at his home Grand Prix. He then took his backing to Fred Opert in Formula 2 for 1978, again with little reward.

    Thereafter Hayje perhaps found his true level and success came his way at last, racing in the European Renault 5 turbo championship.
