This is Te Aurere,a traditional polynesian voyaging canoe with hulls hewn out of totara logs, moored in Mangonui harbour Northland NZ.
She has voyaged to Rarotonga and back, and came in for some criticism for accepting a tow. I thought the criticism unfair, as they were trying to meet a deadline for a festival. A situation the old voyagers never had to worry about.
It made me think that in concept wharrams arent too far removed from the originals.
I dont know what the rig is called,the the three sided sail sets between the two booms visible on the aft mast with the apex down.. It looks like the booms (for want of a better word) on the forward mast are not currently on the boat.
That is the steering oar at the stern.
Traditional boats can come in many forms.
Not great pix I'm afraid, cheap cameras and late afternoon on gloomy days dont go together too well.
