We have always avoided Seymour Narrows on our trips north and would appreciate
some local/experienced insight into the best approaches and timing...we might
try it this year. Assuming a start point of Campbell River and going north at
7 to 8 knots, I would normally plan on hitting the rapids at slack and when
going north, would be looking for a turn from flood to ebb...this normally
allows you to approach the rapids slowly against the flood...then go through
at slack...and then complete the passage with the ebb. Agree? Should the
timing be based on hitting slack water in the vicinity of the old Ripple Rock?
Is one side better than the other/...do you have a choice? We would appreciate
any comments and advise including a southbound passage.

Thanks,

I've been through Seymour Narrows a couple of times in my 6.5 knot
boat - I planned to be at the Narrows (at the <A> on the chart) at
slack, and had no problems - don't recall how close to slack I
actually was. Beware that there is up to 7 knots current off Campbell
River at max flood or ebb! (I tried to keep right both ways...)

I agree completely with Peters approach to Seymour Narrows - just remember,
like Peter says, there is a great tidal run all the way down Discovery
Passage right south of Cape Mudge. If you keep the long run of tidal current
in mind when timing the transit of the rapids you will have no problems.
With our 6.5 - 7 knot boat I generally stay overnight at Campbell River,
usually at Discovery Marina which is the furthest north, and head thru the
narrows the next day. Been doing that for over 10 years with no problems.

< there is a great tidal run all the way down Discovery
Passage right south of Cape Mudge.>

True. One year we were heading north, against the current, in Discouvery
Passage just off Mudge in our 7.5 kn boat. I glanced at the little green
boat on the Nobeltec screen and it was pointed south!. We were going
backwards at 0.5 kn so the computer thought we should be pointed that way.
We moved over towards the west shore where we caught a back eddy and we were
soon going north at over 9 kn. We too, usually stay over at Discouver
Harbor, provision up, etc and then head trough the narrows timed for slack
+/- 30 min, or so. Never any problem. This year on June 2,3,4 & 5 will be
the biggest tides in 50 years. Max current at Seymour predicted at almost
16 kn so they are nothing to fool with. For our non-NW boaters -- there
once was Ripple Rock, just under the surface at low tide in the narrows that
claimed many, many vessels and lives over the years. I say "once" because
they tunneled under the narrows and up into the rock, packed it with
explosives and blew it up in the late 50's. It is still considered to be
the largest non-nuculear explosion ever. I remember it on TV as a kid.

There's a web page on this which is quite interesting, and shows photos of
the explosion (http://www.vancouverislandabound.com/tamingof.htm), but I
assume that must only be the largest man-made non-nuclear explosion. I think
the final explosion of Krakatoa in 1883 is estimated to have been about 200
megatons...

Best regards, Robert Bryett.
