What company manufactured the sailboat used in the movie 'Dead Calm'?

Stormvogel, a 73' ketch was built for South African owner Cornelius Bruynzeel. She raced in several Transpacific Yacht Races (LA to Honolulu) as well as other major ocean races, turning in outstanding times. She was bested in the amazing 1967 Honolulu Race by Bob Johnson's stripped and lightened 73' ketch, Ticonderoga, one of the most beautiful sailing vessels of all time. I believe the naval architect for Stormvogel was Giles VanDeststant. Approximate build date would have been 1965. Probably was built of fibreglass.
