The hazards of Dixon Entrance include complex currents and fog -- a
nuisance from July to September -- when it can be a problem of several days
duration. Swells move into the area from the west and southwest, and even on
calm days the swell is presento


The main exposure to the swell and weather is reduced by crossing from
Prince Rupert into the lee of Dundas Island. Thus, open seas are faced only in
the 10-mile passage between Green Island (near the north end of Dundas Island)
and Tree Point Light (past Cape Fox). Powered vessels may find sea conditions
more of a problem on the return because following seas wil1 be experienced on
the section between Dundas Island and the entrance to Prince Rupert. Radio
beacons for the crossing include:


Prince Rupert - 218 kHz (range 100 miles)
Triple Island - 308 kHz II and V (range 50 miles) ---

The swell itself is not a problem, but with any wind the sea state is
affected considerably. If the wind or swell is running contrary to the current
races of disturbed water occur at several places, and the crossing of these
areas can be uncomfortable. As in other crossings, anchorages are noted where
one may wait for the best time for a crossing. In addition, harbors are
indicated that provide a refuge if conditions deteriorate during a passage.


Open Water Passages of Lesser Extent


There are short periods of exposure as one enters into or crosses some of
the sounds or passages which are open to the ocean, such as Milbanke Sound.
Also many of the inner waters such as Chatham Sound and Stephens Passage are
broad and long and thus offer fetch and conditions comparable to open water
crossings. One may also ha ve routes passing around an open sea cape, such as
Cape Chacon or Cape Decision, where weather and sea conditions are usually
disturbed.


Usually the open water exposure in these smaller crossings is sufficiently
limited as not to be a problem. This does not mean that they should be treated
casua11y. but the discomfort of any exposure is not of long duration. There
are alternative routes that offer more protection at the expense of longer
distances. Caution in choosing the time to cross and careful navigation should
eliminate or reduce problems related to open ~ater exposure.

~~ATHER FORECASTS

North American sailors are fort~nate in being provided with weather fore-
casting services that relate specifically to small craft, both pleasure and
commerciaI. But in the area of this guide the remoteness of smal1 communities
does affect the overaii coverage available. Since the area is also very moun-
tainous, radio reception can be variable and though relay stations are used
there are many areas with spotty or inadequate reception. Considering the
costs and problems involved. the system is admirable, and provides a much
needed service.
