Tom; I may have come across a bit harsh with my earlier comment about taking another look at the chart. I was then and still am, wondering how you came to believe you were working with a falling (ebb) tide?

Tom, The flood flows north and the ebb flows south at Dodd Narrows. When you get a little further north ( Campbell River/ Desolation Sound), this will reverse and the flood will flow south and the ebb will flow north. All that water needs to get out from behind Vancouver Island and will flow either south or north, depending on where you are. When you get further north, the currents run all different directions. Best to check your cruise guides or turn on your current arrows in your navigation program if you have that feature.

I would encourage you to keep your radar on at all times as you will be sharing those waters with cruise ships and ferries. Those big guys are going 20 kts. or more and can sneak up behind you real fast. You got a taste of it yesterday.

Possibly looking at tide tables, not the current tables???
Had a sailor come into Browns Bay Marina a couple of
days ago complaining that the timing for Seymour Narrows
was off by about 2 hours, was going to write gov't a letter.
He didn't understand that tide and current change weren't
simultaneous.

Excellent points. Mitlenach Island in Georgia Strait, between Oyster Bay and Hernando Island is where the N-S floods meet. Mitlenach to the Coast Salish means "calm waters."

Yes, see it all the time. You'd think sailors would be all over current info. I used to enjoy sitting in Pirates Cove watching the confused sail boats hitting Gabriola Pass a couple hours off. Skookumchuck is a crazy one to nail down.

I doubt Tom was confusing tide and current. His timing was early but close enough for Dodd; it was his current direction that was askew. Needs to get a handle on that. I don't see arrows on his digital chart picture...I guess we need him to tell us.

Might not hear from Tom for a bit. Probably waiting at the dock for the night crawlers to come do their laundry in the drink.

Tom:

Great stories. We like the Dinghy Dock pub too, First I have heard that it makes ladies lose their pants!
That sailboat ahead of you at Dodd, reminds me of one of the first transits I made there, in my 30' sailboat. We were heading north, so I timed it to arrive at peak flood current We went through in a flash, then promptly did a 360 before getting set firmly into Northumberland Channel. Great fun. Another time, in my 37' sailboat, we needed to be at Thetis Island in a hurry, so pushed through against the flood. Didn't know till then that there is an overfall of about 6" on a strong flood, but hey, we needed to get through, so pushed the old 55 hp Lehman to "overheat speed" and climbed that overfall in about 10 minutes, just till the overheat alarm started to wail. All good.
Thanks for your stories. Keep them coming.

Tom, I just have one question--did she give you any Klondike Bars for rescuing her?

Like you said, welcome to Nanaimo and good for you; Tom to the rescue.

Now, you might want to take another look at your chart for Dodd Narrows. You were travelling with the flood. Albeit the tail end.

Also, not to encourage you but, with your power, you could have pretty much gone through there any time. Good you felt your way the first time though.

I was not around much on the weekend or maybe would have wandered by. Never quite know what to do with strangers though. Intrusions and all.

At one point I did see you two lollygagging along outside the wine store. I had a notion to call out to Kay and leave you wondering what guy in a strange town knew her...and why.

I took 5 pics of you leaving and can send them to you, if you like, just say how.

If you do go up to Louisa, do yourselves a favour and stop in at Egmont, if there is room. The 2 mile walk from there to Skookumchuck Narrows is well worth it. Especially if you can see the ebb. It's like a giant water slide. Impressive.

Also a preview of what lies ahead, north of Desolation sound.
Thanks Hawg. That would have been great for Kay to have a stranger call her name! In fact it would have been entertaining!

Oh no worries my friend. It would appear I misread the current book (Ports and Passes) for Dodd Narrows. It stated for May 24th:

SLK MAX F/E
12:35a 3:03a +4.1
5:51a 9:04a -5.8
12:14p 3:24p +8.0
7:10p 10:09p -5.4


So from the above I thought I was going to a low tide slack at 7:10P because the F/E was a negative number.

So where did I go wrong?

Help Please....


NOTE:Well my chart stuff won't format properly.

I will look for the current features and turn them on. In the Ports and Pass book, it does have a diagram showing the direction of the flood and ebb. You are also correct I need to get a handle on this.

So from the current predictions above in my other post, how would you know flood vs ebb?

Hell no! The cops had to haul her and her friend to the hospital. By the ring she was wearing, hubby will not be a happy camper when he gets the call. I feel like I was cheated!!!

So in talking to our friends it would appear the reason Dodd narrows was still in flood was i had arrived EARLY by an hour.

The positive numbers are the max current during a flood tide and the negative is the max current on the ebb tide. At 12:14 it was slack after the ebb, so a low water slack. Then the flood started and the max flood current was 8 kts at 3:24. Then high water slack occurred at 7:10. Up until 7:10 the tide was flooding north.

Ok, let's see if I can do a decent job here.
I don't have Ports and Passes at my finger tips but in any event, let's work with what you gave me.

SLK MAX F/E
12:35a 3:03a +4.1
5:51a 9:04a -5.8
12:14p 3:24p +8.0
7:10p 10:09p -5.4

To get really simple, let's work backwards:

7:10p 10:09p -5.4
This is the 3 hour period AFTER the slack you aimed for.
7:10 = slack
10:09 = max
-5.4 = rate of current of an ebbing tide at the 10:09 max.

You had the time right and yes you were an hour early, as I noted in a previous post.

Now, this is just for general information.
Because I am old school, I would be working with paper.
A CHS chart for flood and ebb arrows.
A CFO Tide Table
A CFO Current Table.

Dodd Narrows May 24 2016;
CHS shows flood running to the north.
Tide table puts high tide at Ladysmith, south of Dodd, at 8:10PM (PST)*
Tide table puts high tide at Nanaimo, north of Dodd at 8:21PM (PST)*
Current table puts Dodd slack at 6:10PM (PST)*

All 3 references confirm state, direction and times.

*Time data can vary between PST and PDT depending on publication. Always confirm.

In the olden days, we did not have current tables. Just a reference tidal point.

For example, Skoocumchuck Narrows slack could be up to 4.5 hours after the high or low tide at Point Atkinson, over 50nm away. Hence the confusion refered to by Ted and Keith.

So, anyone not up to speed with tides and currents could legitimately ask how slack in the above post could occur two hours before high tide.

Current and tide are two entirely different animals.
Looking at Dodd narrows, slack occurs when the water level north and south of the narrows equalizes.

Because, in the case of the flood, the north fills from many areas, it equalizes ahead of high tide. The tide then just continues it's overall general rise for another 2 hours.

True slack water occurs for only a few minutes. However the rate of current is so slow before and after slack tide that it may "appear" to be slack for a long period of time.


Growing up on Malaspina Strait we liked to fish the slack, which could vary from 30 minutes to a couple of hours, depending on tide range and location.

It is fun and interesting to track the tides and times through Juan de Fuca and into/out of Georgia Strait.

Next lesson:
The Rule of Twelfths and how to crack a beer with a cod jig.
