Lightweight sailing craft with outrigger - has tubular A=frame supporting mast and outrigger with hull ends joined by horizontal strut

摘要

The lightweight proa type of sailing craft has a flat tubular A-frame with the wide spaced ends secured on the main hull and the closely spaced ends on the outrigger. The main hull ends are also joined by a horizontal bracing strut which supports the mast as well as the centreboard. The centreboard is pivoted from the mast and can be set at different angles before and after the mast to trim the craft for different wind directions. The craft can be sailed with the wind on either side, with further trim achieved by tilting the mast.
