CD-14 Daysail

I finally got back on the water for a day, but in a sailboat rather than a canoe, and carrying oars rather than paddles. Unfortunately, while I had planned to take the camera as always, I somehow walked out of the house without it, so I’m sorry, but no pictures.

My son and I had put new bearings on his boat trailer a couple weeks ago. He had been told by the previous owner, when he bought the boat, that the bearings had just been done. I don’t know what was done to them, but inspecting, greasing, and replacing worn parts were none of the things that were done to the trailer. The bearings were shot. The races were pitted and gouged. One hub was all but destroyed, so we replaced it with a new hub, race, and bearing set. The right hub looked passable. Although when we finished, the new Bearing Buddy would not seat in the old hub, indicating that it was worn and would also need to be replaced.

We made an early start on the day, bought another replacement hub, race, and bearing set, and replaced the worn hub. We took a ride around town, stopping every couple miles to feel the hubs to make sure they were staying cool, meaning that we had gotten them properly greased. With that done, we headed for Kaw Lake with a lunch stop with the granddaughters in Ponca City.

The Cape Dory 14
Their boat is a Cape Dory 14. It is 14-ft 6-in overall, 51” beam, 6” draft board up, and 36” with the board down. It is gunter rigged, and one of 652 built between 1964 and 1973. My son was looking for a good pulling boat that could also be sailed. He loved the lines of the classic Whitehall, but with a $12,000 price tag on the Whitehall, decided the Cape Dory 14 much more within reach of his wallet.

When we arrived at Kaw Lake, we didn’t need a calendar to tell it was Labor Day Weekend. There were easily a hundred boats buzzing about and beached on the shorelines. We charged forward, however, and launched as planned. There was barely a breath of air even though we are in a state where a 20-mph wind is normally called a calm day. We sat becalmed in simulated ‘storm-at-sea” waves generated by the wakes from all the passing powerboats. No sooner would a zephyr attempt to caress the sail than a wake would flail the sail around and smack the zephyr in the face. We did move, however slowly, and got plenty of practice sitting on the leeward side to hold the boom off to the proper side. After a couple hours and a couple miles, we came about for the slow drift back to the ramp. We arrived at the ramp at 6 pm, and of course you know what that means. Everyone was wanting off the lake at the same time to make dinner, so it took us an hour of sitting in line waiting to gain access to the ramp.

This brailing line is on a gaff-rigged sloop, but nicely illustrates
how it works.  Credit:
In spite of all this, it was a wonderful day. The girls had a good time, as did we. We got on the water after being aground way too long, and planned a couple new projects for the boat to improve handling and convenience. I’m trying to talk my son into installing a brailing line. As the rig is now, when the halyard is eased, the boom and sail fall into the boat or overboard where it lies until the sprit is all the way down. You then pull all the sail, boom and sprit back aboard, where they are in the way of everyone and every thing. The only recourse then is to stand teetering in the bow while holding the boom and sail up while lashing it all to the mast. A simple line from an eye on one side of the mast would come down and through an eye on the bottom of the after part of the boom, then back up to a cheek block on the opposite side of the mast, and then down to a cleat. To pull into a pier, the beach, ramp, to have room to row, or just to stop and eat lunch adrift, all that would be needed would be brailing up the boom and sails, and everything would be out of the way and secured in place. When needing to get underway again, just throw off the brailing line, pull the sheet in, and off you go. Even one of the girls could brail the sail up when not needed.

So, we had lunch out on the way to the lake, and after the sail we had dinner out. I didn’t get home until 11-pm. All told, it was a nice change of pace and a chance to be on the water. What could be better? Well, maybe a breeze, but we need not get picky. Today, its blowing 25, gusting over 35, so unless a few folks have holed up in a creek somewhere, I doubt much of anyone has gotten on the lake today.

Minor Repair to a Paddle Blade

This is a common repair, but one which should be tended to right away before water intrusion rapidly deteriorates the blade further. If you know how the blade was damaged, most of the mystery is solved as how to best prevent its recurrence. It becomes a question of whether the wood was damaged by some accident or checked. Checking is a natural opening of the fibers usually along the grain. It can, however, start following one grain and make an irregular diagonal jump to follow another grain depending on the forces working on the wood. Checking usually occurs because the wood was not completely seasoned, and is now contracting, or because of weathering from not being properly protected from the elements. In something as thin as a paddle blade, the check will normally be evident on both sides of the blade.
A 4 1/2" crack that split the wood and varnish.
The blade is cracked when an external force is applied, the wood is bent, and the fibers on the convex side of the bend are unable to endure, and a crack occurs there first along the fibers. Initially, the crack may only be visible on what was the convex side, but, of course, if the force continues, the wood will fail completely. My paddle blade only showed a crack on one side, splitting both the varnish and the wood, but not being evident at all on the other side. We don’t know how it happened, but apparently pressure caught the blade in an unsupported position and flexed the blade.

Using a Dremel tool with triangular bit, a "V" groove was cut
half-way through the paddle.
On plain paddles, the crack would normally go all the way to the end of the blade, since the wood is diminishing in both thickness and strength as the blade tapers. To start, I carefully highlight the crack with a pencil so it is easier to follow while sawing. The crack is sawed through to remove any broken wood fibers, and also to open the crack enough to effect a repair. I use a saw blade just wide enough to remove the damaged fibers and no more. Scotch tape is applied over the crack on one side, since epoxy won’t adhere to it, and slightly thickened epoxy is then forcibly brushed into the crack to remove all air. As described below, masking tape is put on either side of the crack on the working side of the blade.

The groove was epoxy filled, sanded smooth, and while probably
not necessary, a single layer of fiberglass was applied to the entire
back of the blade.
On this blade, a Bending Branches BB Special Bent-Shaft paddle, the RockGard epoxy edge that is applied around most of the blade’s edge, protected the blade and kept the crack from running all the way to the end. Since the blade was not cracked through, nor to the end of the blade, I routed a “V” groove about half-way through the blade. Masking tape was used to outline the crack both in width and length. This does two things---it greatly minimizes mess and the sanding time required later, and since epoxy shrinks a bit as it cures, it allows the epoxy to stand a bit above the surface of the paddle. This makes it unnecessary to come back and add a touch more epoxy later. Once the epoxy becomes tacky, so it will no longer run, the masking tape is removed. Don’t let the epoxy cure with the tape in place.

Finished with several coats of spar varnish, the repair is
hardly noticeable.
Other than varnishing, this is really all that is necessary. However, I have a long history of always wanting to do something extra. This habit has gone on long enough that it is now impossible to ignore. So, I applied a single layer of epoxy and fiberglass to cover the entire back of the blade. I doubt the materials required added as much as an ounce to the weight of the blade, but backed up the repair and strengthened the blade so that I can now either paddle with it or use it to dig trenches. Once everything is sanded smooth, just apply as many coats of varnish (minimum of four) as your patience will allow.

River-Running Sphinx Moth

The sphinx moth, also called a hawk moth or hummingbird moth, is huge, and its behavior closely mimics the hummingbird. It flies erratically, darting about so rapidly that it is often difficult to follow with the eye. Part of this, however, is that it feeds most commonly in the evening when light conditions begin to fade. They are big, often having as much as an 8-inch wingspan, and feed on flowers with a proboscis (feeding tube) that is anchored in its tail end and still extends as much 10-inches from its head, so certainly an amazing creature. They love pink, red and orange Four O-Clocks, a self-seeding and very, very prolific flower that will take over a flowerbed. They also love petunias and evening primrose.

There are many varieties.  This one is a pink-spotted sphinx moth
because of the pink spots on its lower wings to either side of its body.
This one visited Jean in the yard, so she brought it inside for me to see. Here it appears to be helping me find camping spots on a Mississippi River map.

Running The Amazon

Running The Amazon, by Joe Kane, pub. by Alfred A. Knopf, NY, 1989, 277pp.

No one had ever done a source-to-sea expedition of the Amazon. A few had paddled or rafted short sections, but a previous attempt at running the entire river in 1976 ended when the expedition leader died within the first three minutes of having his boat in the water. About a half-dozen other attempts were made, two more people died, and none succeeded

The river gradient is five times greater than the Colorado River, and drops 13,000 feet in one 300 mile section. The American Whitewater Assoc. classification for rapids has six levels. Level six is labeled ’extreme.’ It reads, “These runs have almost never been attempted, and often exemplify the extremes of difficulty, unpredictability, and danger. The consequences of errors are very severe, and rescue may be impossible.” The Apurimac ran from threes to many sixes or off the scale.

The river’s source is in a snowfield high in the Andes Mountains. At 18,000 feet on the side of Mount Mismi, South America’s continental divide, their first challenge would be altitude sickness. The Apurimac River would shortly begin after a few miles of following the snowmelt stream. It led them into Black Canyon, one of the world’s deepest gorges, at more than twice the depth of the Grand Canyon. At one point the canyon rim perches two and a half miles above the river, or over 10,000 feet deep. The roar of the cascades is so great that the native Quechua name for the river translates to “The Great Speaker of God.”

The expedition started with a team of ten, nine men and one woman, the team doctor. It ended with four members by the time they had completed the 4,150 mile run. They introduce the reader to the river, jungle, small, sleepy native villages, drug-smuggling plantations, being shot at by guerilla gunmen, violent storms, equally violent confrontations among team members, and pretty much everything else you could expect from such an expedition. This is definitely a good read.

Stumpy Lake - 2

The cypress swamp showed nature in full bloom.
In the southwest corner of the lake, I encountered a channel that led west. Investigating it carried my deep into a cypress swamp. The air was filled with the songs of birds, and wildflowers grew everywhere. I went as far as I could until I was just about to run out of room to turn around.

Parts of the lake were carpeted with millions of floating seeds.
As I paddled up the west shore, I drew close to a couple of kayakers. I was about to speak to them when the man ran the bow of his kayak into low foliage of a small, young cypress tree sitting right on the edge of the shore in front of a cabin. Any chance of a conversation was ended when a man came running out the door of his cabin yelling. I first thought he was wanting them to get away from his property, but instead I heard him warning that there was a water moccasin in the cypress tree. The paddler backed away as he looked about, and said that he didn’t see anything. The man approached the tree and said that he had just been out there a few minutes before and saw it entwined in the branches of the tree. After looking about, he agreed that it didn’t seem to still be there. A bit put off by the wildlife in the immediate area, the paddling couple decided to move on down the lake.

Gliding through the cypress swamp.
E-Z Launch.  This is a single boat launch.  The one at Stumpy
Lake could handle two boats at once, one off either end.
There were no good places for launch and take-out from the shore, but they had built a beautiful metal pier, float, and launching wharf. The wharf, attached to the end of the pier, is called an E-Z Launch, made by E-Z Port. The company made a name for itself making launch floats for PWC, or jet skis, allowing them to be literally driven onto the float and pushed off. This launch is for paddlecraft, and includes a seat the slides out over the canoe/kayak to enable disabled or elderly people to get into a canoe. This one was a double launcher, meaning it was long enough that two craft could be placed on the ramp and loaded, then launched simultaneously. Your canoe would be placed on several cross pipes covered with PVC. Once loading, you’d pull on the side rails and pull yourself onto the sloping ramp and into the water. It is fantastic for plastic boats. I saw several launch, and they shot out onto the water’s surface like a launched watermelon seed. I used the launch, since there were no alternatives, but found it greatly lacking for my light Kevlar canoe. The cross bars are far enough apart that the boat flexed alarmingly, and buckled as it passed over each pipe. There’s an area where the canoe is half on the launch and half water-borne where it is totally unsupported in the middle. The canoe clearly exclaimed that it was not having a good time. Returning, you’re supposed to just run the bow up onto the ramp, use the side rails to pull yourself up the incline and onto the flat section, and then disembark. I chose to just get the bow onto the ramp, and then stepped onto the side rails. Once I got up far enough, I stepped onto the end of the ramp, and just scooted the canoe up between my legs. I’m glad no one was taking pictures. There was nothing graceful about it, but I didn’t want to stress the canoe any further. Again, fantantastic idea and great for plastic boats, but for ultra-light craft, I’d recommend finding some alternative. Had it not been for heavy growth alongside, placing the canoe in the water alongside the float and boarding from the pier would have been the best option.

With Buddy loaded back on the Ram, I grabbed my packed lunch and waterbottle and settled at a picnic table for a quiet, leisurely lunch. It was a short trip, but everything I could want from a paddle.

Stumpy Lake, VA

I didn’t have a lot of time, but Stumpy Lake was nearby and accessible for getting on the water. I was a bit concerned about the name, and when I met a fisherman launching ahead of me, I took advantage of the chance to question him about it. He assured me there was plenty of water unless I got close to the shores. In fact, I found plenty of water everywhere, and only rubbed one stump slightly.

Stumpy Lake, quiet and beautiful.

A very low single-lane causeway bridge connecting the highway
and a golf course and residential area.
The lake was a nice pale green color, and it was evident why fishermen were launching throughout the day. The lake was surrounded and peppered with mature cypress trees. The sun filtered through the beautiful foliage and dappled the water’s surface. An added advantage is that only hand-propelled craft are permitted on the lake. Paddling slalom in and out among the cypress reminded me of my days paddling Trap Pond in Delaware with David Sockrider.

Two female mallards, one by a cypress tree.

As usual, I paddled the entire circumference of the lake. Near the dam, seeds were being transported on the breeze. They were a bit smaller than a grain of white rice and surrounded by a tuft of down a half to ¾ inch in diameter. At times it looked like a snow storm, and toward the south end of the lake, the water was covered by large blankets of white. I wanted to be able to identify what I was seeing, but local workers in the park had no idea what they were. Indeed, they hadn’t even noticed them. So, I contacted the Virginia Department of Conservation and Recreation. I described the seeds, and said that if I was home on the plains, I’d swear they were cottonwood tree seeds, but didn’t think there would be cottonwoods in the tidewater regions of Virginia. I am grateful to their chief biologist, J. Christopher Ludwig, who responded with the following: “I am fairly sure your seeds are from the Salix Caroliniana, the Carolina Willow, a fairly common tree on the borders of the lake. By the way, Willow and Poplar are in the same family--Salicacease--so your guess on cottonwood was right on.” So that told me two things I didn’t know before---the cottonwood is a poplar, and willows and poplars are of the same family. Cool!
