I just reserved a kayak from Sydney Harbour Kayaks, they supply Boreal Design kayaks, I asked for the longest thinnest single they have, I am hopeful that it will be the Ellesmere which looks like a nice kayak. I am renting all the equipment and will have to revert back to the Euro paddle as I have not been able to find anyone that can rent me a Greenland Paddle.
I have found a couple of contacts through a facebook friend who I am going to work with to go on a guided paddle in Argentina, it looks like there are some wonderful paddling opportunities in some of the massive river deltas. more on that as it firms up.
