The 57-SK was the Bill Dunsmore and Tony Maricich team. Don't recall Bill doing much driving, but Maricich was a great wheel-man (another local SoCal fireman). I never ran the twin engine outboard at the Catalina Ski Race, first time was 1966 in the 16' Tahiti jet pulling Women's Open class (took second, about 1 hour 30 minutes, Janie Welch beat us by about 3 minutes). Only pulled Chuck Stearns at Catalina (2 overall wins and another overall title with Jeff Wooten) with the 24' Schiada. Also got 4 overall wins with Chuck at the around Ana Capa Island Ski Race out of Oxnard Marina -- although a shorter distance than Catalina, a tougher race IMO.
