Ripple Rock

Every year when the captain (my captain, that is) takes his commercial troller from Vancouver Island to the Queen Charlotte Islands on the northern coast of British Columbia (and back again), he has to go through a tight passage called Seymour Narrows.

Located just north of the town of Campbell River, this stretch of water was described by Captain George Vancouver as “one of the vilest stretches of water in the world.”

Whenever I have accompanied “my” captain through the narrows, I’ve nearly given myself an ulcer beforehand, as Seymour Narrows has such a terrible reputation. Yet each time, going through the passage has been a piece of cake, with calm waters. That’s how it should be, if you wait for slack water, between tides.

The passage through Seymour Narrows is now much safer thanks to the removal of the tops of Ripple Rock,  a submerged twin-peak mountain that lay just nine feet beneath the surface of Seymour Narrows. According to Wikipedia, it was a serious hazard to shipping, sinking 119 vessels and taking 114 lives.

In the case of the William J. Stewart, when it struck Ripple Rock  in 1944, I’m not aware of any loss of life, and the ship was beached and later restored. It was due to be scrapped in 2017.

On April 5, 1958, after twenty-seven months of tunnelling and engineering work, Ripple Rock was blown up with 1,375 tons of Nitramex 2H explosive. It was quite the project.  A 500-foot vertical shaft was built on Maud Island, and then a horizontal shaft of 2,370 feet  was drilled out to Ripple Rock. From that point, two vertical shafts were drilled up into the  peaks, with shafts for the placement of the explosives. Very advanced technology for 1958.

I think those columns of smoke are blowback  from the explosion, coming out through the drilled shafts.

The explosion spewed debris almost 1000 feet into the air falling on land on either side of the narrows.  After the blast, the two peaks were 13.7 m (45 ft) and 15.2 m (50 ft) underwater.

Some very smart engineers had the foresight to detonate the charge at a time when the tide was running its fastest, so the rocks  blown off the tops would not fall straight back down onto the peaks, but rather, be swished along beyond them.

Even after the top of Ripple Rock was removed, it remains a challenging route. In March 1981, the Star Philippine, a freighter, ran aground in the narrows.

When the captain was coming home from a summer of trolling, he took pictures of his navigation instruments as he went through Seymour Narrows quite close by Ripple Rock. The red triangular icon represents his boat as he is heading south, just past Ripple Rock. Arrows show the direction of the tidal flow at that time. You can see the depths of the peaks as 15.2 m, and 13.7 m.

In the monitor of the depth sounder below, you can see the twin peaks of the rock. The reading is taken on the far right where the scale is marked. This tells me that the boat has just passed the second of the peaks of what is left of Ripple Rock.

Even knowing that the rock has been topped, I still have a healthy respect for this stretch of water. The colour photos (near the beginning of this post) of the swirling eddies are recent, well after the explosion of Ripple Rock, so you can see that going through Seymour Narrows when the tide is running full is still not a good idea.

My preference is to stay on land whenever possible.

Tide Out, Fish In

At first glance you might think it’s a sandy beach, but your nostrils will tell you that iodine  breeze holds the smell of low tide.  That sand would be very soft to walk on and I wouldn’t advise it. When the tide comes in, all that “sand” will be under water. Meanwhile, there’s no telling how far you would sink into that sea bottom.

This is the east side of the causeway that divides the wharves where fish boats can tie up. It is what they call the new side, more recently dredged to provide more moorage and shelter for local boats.

The older side is more crowded because “the old salts” tie up there. It is busy with fishermen getting their boats ready for a summer of salmon and halibut fishing, often far enough from home that the men and their boats may be gone for many weeks.

You can see the roof and the rigging of the Captain’s boat on the bottom right-hand side of the photo below.

The new side is also busy, but is more convenient for boats that come and go more frequently.

Those who have fish for sale will want to moor on the new side. It is handier for the public to visit for dockside sales of whatever is in season. It might be prawns, shrimp, salmon, halibut  or other. Today it is halibut. The customers lined up on the dock know that they have to buy the whole fish. The price is high, but they gladly part with well over $100 for a small halibut. These flat fish have a delicate white meat which, though highly priced, is also highly prized. If you could see what the fishermen have to risk and endure to catch and bring these fish to harbour, you would say the price is a bargain for the customer.

As you can see, there is no shortage of people wanting fish for their supper.

I have removed the name and number of the boat to allow some anonymity for the boat owner.

A Proper Prop

No wind or rain today! Here’s a chance for the Captain to put the troller on the grid and exchange the old prop for a new one while the tide is out.

026

He’ll have to work fast before that water rises again and floats the boat. As soon as the tide has dropped enough to give him a working surface on the grid, he begins.

013

The old prop needs to be pulled off, but that isn’t so easy. Nor should it be. It’s meant to be on there good and tight. Not something you want to have wobbling on the shaft or twirling right off the shaft and whooshing away into the deep. It’s hard work but the wheel puller (fishermen often call the prop a wheel) that he puts around the propeller puts physics to work and with a bit of elbow grease and a few grunts, the old prop pops loose.

005

This boat is going nowhere until the new propeller is put on. You can see the gadget that helped pull off the old prop lying on the ground next to blue kneeling pad. The propane bottle on the left was used to heat and expand the hub of the propeller, making it easier to release it from its tight fit on the shaft. Like holding a stubborn jar lid under hot water to make it easier to open.

015

The new propeller is placed on the shaft. It’s a bit like changing a tire only harder work. The blocks of wood under the bottom blade will stop the prop from wanting to turn as the wheel nut is tightened to hold it in place.

017

020

Whew! That was hard work. The Captain drops the pipe wrench on the ground while he stretches his legs and gives his arms and shoulders a rest. But OH! Look at the back of his coveralls. Which washing machine will want that mess in its tub? Bottom-of-the-boat scunge and copper paint. So much fun for Ahab’s wife.

024

The annual spring cleanup of the hull of the boat is yet to come. A proper shipyard will be needed for that job. For now, Ahab’s wife will try to enjoy how shiny the new propeller is and forget about how grungy her Captain looks after a hard day’s work.
