| Fine Tolerance and the North West Passage. Newsletter No 6. 03.00 Zulu Tuesday 10th August Position : 69 deg 16 mins North. 117 deg 09 mins West We are currently inside the Northwest Passage proper, after travelling 4000 miles from where we wintered in Port Townsend in Washington, USA. While the transit of the Northwest Passage by boat is generally taken from the Arctic Circle on the Pacific Side of the America's to the Atlantic side the actual Northwest Passage itself is that section from the Beaufort Sea to Baffin Bay. Our position right now is in the middle of Dolphin and Union Strait which so far has been treating us rather kindly and only throwing up the odd blocking floes of ice which up to now haven't presented to much of a problem. However it is the eastern half of the strait that still has heavy ice so only time will tell how we will take it. Once through we should then have a pretty clear run up along the south shore of Victoria Island to Cambridge Bay. Well, here's hoping so anyway. We left Tuktoyaktuk with a good forecast and made 20 nm in the first 3 hours but unfortunately the wind shifted around to blow hard on the nose again. With it up came the short, steep, sharp seas as well and before long we were under a double reefed main and the small storm jib. This was the point of no return, we both felt it. To continue past Cape Bathurst was the final commitment to go through to the other side. As Fine Tolerance ploughed into the cool waters burying her nose and covering her foredeck time and time again the thought was definitely there, 'are we ready for this'. After all we are not your macho sailor types, just your average cruising couple. What should have been a pleasant 20 hour sail to Cape Bathurst turned into a very wet, upwind battle and it wasn't until the next afternoon that we sighted the Cape. As we neared the Cape the wind dropped away some and I guess, probably through inaction we continued onward and as we rounded the Cape we put the engine on once again. The last ice chart we had seen told us of a 3/10 water surface coverage by
ice in this area but we were hoping that the wind and the previous few
days
had diminished this relatively high number somewhat. One thing with ice is
that it dampens all swell and we could feel a small bit of swell under
the
boat still. Also in the clear conditions that now existed we had a
refracted
light. This is an abnormal refraction of light at sea produced by an
inversion of temperatures in a layer of air, which in turn creates
variations in density of the air. Light rays passing through this layer
are
bent or deflected in excess of normal conditions. In real terms this gives
us a double horizon. The one we usually see at around 3 to 4 miles and
another one that can be ten or twenty miles away. (One of the reasons that
Franklin, his men and ships were not discovered for 10 years after they
went
missing was that all the charts of the time showed a mountain range
blocking
the end of the sound that he had sailed down. In actual fact there was no
mountain
range and the sound led on into what we now know as the Northwest Passage.
Researchers now believe that it was the refracted image of a mountain
range
many hundreds of miles away that caused this error on the charts.) In our
case, when we can see ice on the horizon and a dark refracted image above
it, it indicates to us that there is open water on the other side of the
barrier
immediately in front. If the refracted image has patches of dark and light
then it is an indication that there is a mix of open water and ice. All
white, of course, means
all ice. The horizon in front of us showed a lot of dark patches and so
rather than hug the shore of Franklin Bay, thereby adding another 40 plus
miles to our distance to travel, we decided to gamble that we could cut
straight across the Bay to the other side. The worst that could happen was
that we would have to backtrack and then follow the coast.
Generally we each do shifts of 3 hours at the helm and after retiring
below
for a nap I emerged on deck to find Liz just rounding a large ice floe
that We'll leave you with a description of the layers of clothing we each wear to go up into the cockpit to steer Fine Tolerance. Liz: thermal underwear (long john's & long sleeved spencer), long sleeved wool jumper, long sleeved polar fleece sweat shirt, polar fleece sweat pants, down jacket with hood , 2 pair of socks, a pair of ug boots, scarf, polar fleece hat, a wind helmet which is polar fleece type of balaclava & over everything an insulated working suit & gloves. Phil: thermal underwear, long sleeved warm top, polar fleece sweatshirt, polar fleece sweat pants, two pair of socks, wool beanie, down jacket with fur hood, insulated working overall suit, gloves and boots.
