D Gordon's letter ‘Mysterious Maori Navigators' where he holds the opinion that the waka voyage of Jack Thatcher and his crew toward Rapanui is a total fraud.
I have some months at sea on the bridges of various Merchant vessels between Tauranga, Korea, Japan, East Coast of the US and Europe as well as some decades as a small vessel sailor including around 10,000 blue water miles on Gemini Galaxsea. I have been lucky enough to have enjoyed tutorship on Polynesian Navigation methods delivered by Jack Thatcher. I am proficient at navigation in the European sense and I found the subject of Polynesian methods as explained by Jack to be fascinating, the icing on the cake as it were.
Jack's crew will be given the opportunity to put many of the methods of Polynesian navigation into practice while engaging with the everyday rigours of existing on a small waka for some months over a long stretch of ocean. They will be able to check the two navigation methods, European and Polynesian, against each other, and have a GPS for safety.
There is absolutely nothing fraudulent about Jack Thatcher, his leadership, his motives or this amazing voyage he is taking a few very lucky adventurers on. I reckon, without much effort, the very negative and suspicious D.Gordon would be able to suck the colour out of a rainbow. Piffle to him, I'll put my money on Jack anyday.
