I've been reluctant to post James Wharram as most of my readers are already aware of him. You may not be aware, however, of this little beauty, a tacking proa with crab claw sail which he initially designed for the Melanesians with an eye to conservation of the trees the Melanesians typically use for creating dugouts: "The 'MELANESIA' is to be used in the traditional manner as a small inter island sea truck, for daily commuting to their gardens, for out to sea fishing or just paddling around to see friends, families or nearby islands." I'd love to hear from anyone who's built or sailed one of these and also a Hitia 17.
Mr. Wharram and Hanneke Boon, his partner in design and life, are recognized as two of the most influential designers to bring the Catamaran into our era, and one of the most effective proponents of the self build community. They have a large and loyal group of builders and are responsible, at least tangentially, for much of what actual seasteading is done today.
PS. Just recieved a link from Creed O'Hanlon @ A Tiki in Thailand on the latest update/letter/whereabouts/and goings on from Mr. Wharram and Ms. Boon here.
