From the Coastal Trekking Pahi 26 to the impressive 63' flagship of the Wharram fleet 'Spirit of Gaia' - the PAHI shape is more evocatively 'Female' than the Classic Wharram designs.
Constructively, they are simpler to build, using epoxy fillets instead of more difficult wood joints. They are designed to use quick growing softwood plys, coated and glassed with epoxy to achieve a durable finish.
The PAHI designs were the first to use rope lashings to attach the crossbeams, giving a shock absorbing effect, without the need for metal fittings.
The Pahi 42 'Captain Cook' design set fresh ocean cruising standards when she was designed in 1979.
The Pahi 63 was designed in 1986 and launched in 1992 to become the new ocean going flagship for the Wharram family. During the construction of 'Spirit of Gaia' many unique new solutions to plywood and epoxy building methods were developed, which were later incorporated in the larger TIKI and ISLANDER designs.
The Pahi Building Plans were drawn in the late 1970 and 1980s. They follow a sequential drawing layout, drawn to scale on large sheets, showing the boat at different building stages and clearly showing which parts are added at each stage.
