Mai Tai and Pumpkin Eater are two different boats. Last time I saw it (12 -17 years ago) Pumpkin Eater was called Growler and based in Botany Bay. Lach Percy owned her. She was very soft and only lightly built. I knew one of her builders (Peter Garden) and he used 10oz cloth as the laminate.
Mai Tai was based nearby for a while. She was moored in Kogarah Bay and for a while was called Miranda Hi fi. She had beam problems back in the 80s and cracked the rear one when pushing hard against Bullfrog.
Both cats were sisterships - Shockwave 37s. They would be getting very old now - as they were lightly built they must be getting close, or past, their fatigue life. I ran into Growler (Long story but they were on port) in a very light breeze. Rather than whack them with a fast moving Twiggy float bow I slowed down and touched with my main hull
bow. No bank, crash or crack, just the gentle sound of a thin laminate bending out of the way - left a crease but no break in the laminate - very very thin. I would not like to be out in one of the these old boats in a blow offshore
