The Pacific canoes and cats are lanteen. You still have to have a center board to reduce leway.

What everybody used to do was sail down on a latitude. All of your land masses run north south and all of your wind runs east west. This how they got back and forth. I don't even think the Vikings had figured it out as far as sailing against the wind. I think someone in the Middle East came up with the way to do it./p>

I think the technological hurdle that must first be addressed is that of the massive center board. Once you've got that in place, any time you are out with two sails you're going to figure out the lanteen part.

No doubt the riverine tribes in North America and along the Amazon in South America had little use for center boards~
