Thanks, Tor. Yeah, I've got all the books and reports of pretty much every NWP expedition from the 1600's to present, including the more recent attempt by kayakers, sailors and rowers. What we're discussing right now is whether it is best to wait until mid-late July to determine if the more northern areas (Victoria Strait up through Prince Regent Inlet) will be open or to get a jump on the season and depart Tuk in late June (west-east) and hope by the time we get to King William Island the above-mentioned sections will be open.
In the first case, we will reduce the risk of yet another partial trip, by ensuring the NWP is open - but we take on the risk of having less time before winter sets in. In the second case, we cover the distance as soon as the southern portion is open - but run the risk of being stopped by ice halfway through.
So, I'm asking for thoughts on the subject. I appreciate your references and we're unable to rely upon past human powered attempts, due to multiple variables (lack of experience, speed, poor planning, etc...) and the fact that only one kayak expedition has attempted east-west.
