Of course you should keep the human powered watercraft separate from the motor powered vessels.
Side note: Another Arctic rowing challenger with a 17.5 foot Norseboat named "FAIRMONT'S PASSION" preparing to depart Inuvik yesterday, down the MacKenzie River, decided to cancel their farewell celebration because of forecast strong winds... disappointing I'm sure... but what stands out... ROWBOATS ARE A POOR CHOICE FOR TRAVELING ON ARCTIC WATERS! YOU CANNOT ROW IN WINDS ABOVE 10-15KTS. Paddle into 10-15kts? Yes, but for how long might be another question to ask kayakers. Bottom line - humans against the Arctic - you must pick your battles if you expect to survive and live to see the end of the voyage.
When Roald Amundsen was asked how he made his historic Northwest Passage he said "I observed how the people who have lived in the Arctic have survived for thousands of years. I simply followed their tried and proven ways. I adapted and thoroughly enjoyed myself."
I've never seen a native rowboat in the Arctic. Well, except when brought here and being rowed by "outsiders." On the other hand you see native built bone and skin kayaks that have been used in the Arctic for hundreds of years.
Undoubtedly Amundsen was right - When in Rome do as the Roman's do!
That said... lets see how it goes in 2013 for rowboats, kayaks, sailboats and motor yachts challenging the Arctic.
