Aluminum rivets in fishing kayaks and boats

You may have an outfitting project in mind, such as attaching a rod holder to your kayak, or you may just wonder how strong are Wavewalk kayaks and boats built.
More generally, how well do aluminum rivets work when used in kayaks?

Before going further, we need to explain that nearly all modern kayaks are made from Polyethylene, a polymer (plastic resin) softer than steel and aluminum, and even softer than fiberglass, which is why it requires the use of special rivets that split in three and provide a better grip over a broader surface.
These rivets go under commercial names such as Tri-Fold, Tribex, etc.

Alumium rivets are used for attaching kayak parts together, such as the 14 rivets that attach the W700 Saddle part to the Twinhull part.
They are also used for attaching accessories such as handles, pad-eyes (eyelets), etc.

Here is a little experiment we did –

We riveted together two pieces of Polyethylene that we cut from a part of a Wavewalk kayak. We used just one rivet for this.
We hung one end of the joint pieces of plastic from a basketball pole, and on the other end we hung a fish scale.
We hung a travel bag from the fish scale, and filled the bag with bricks.
We stopped after ten bricks, because the dial on the fish scale had ran full circle, and stopped at 50 lbs.
At this point, neither the plastic pieces nor the rivet showed any sign of stress.

Needless to say that the effectiveness of a rivet depends on more than just the force applied on it in lbs, and additional factors are very important, such as the angle of the force (vector), leverage (a critical factor), the temperature of the plastic (hot plastic is softer), etc.
If we had attached the parts in this experiment differently, we would have seen different results.

Wavewalk 700 with an outboard gas motor, and with an electric trolling motor

By Joe Stauder

 

We took our W700 Demo unit out and had a blast running our little Honda 2hp (gas) & our 36lb thrust electric around.
This is the only kayak I know of that has the ability to be used with a paddle, or an electric trolling motor, or a gas out board for propulsion.

 

My son just loves to paddle, and as we all get older a little help getting back to the launch with an electric or gas outboard sure comes in handy.

Happy “Sunnie” Labor Day

By Jill Toler

Due to a host of things; such as an infection, a tree on my house, storms, and heat indices that hovered somewhere near “pit of hell”, it has been a while since I have been on my W700. That was all remedied today with a trip to Upper Broad Creek with my other fishing buddy, Marla. Marla knew that I had been kayak fishing and thought she might want to get in on the action so, one day she purchased a kayak from a friend. She needed a maiden voyage and now that Hermine had finally left town, today was the day.

We got launched and Marla was looking comfortable so I pulled out my fly rod and tossed a popper towards a little stump. The water was very high and the wind had kicked up pretty good but, it only took a few seconds before I had a strike. And a miss. Okay, let’s try this again. Get in position, sling about 40 feet of string to the right of the stump, and SWIRL! Another miss. Really!!! Nothing to do but change the popper. I chose a smaller popper in the same chartreuse color and tossed it at the very edge of the reed grass since I figured the high water would have the fish up in the grass. SWIRL, STRIKE, and TIGHT! Hot diggity dog, I caught a fish. A very cute little pumkinseed.

I checked on Marla then started working a stretch of bank that had reed grass, stumps, and some downed timber; in other words, sunnie paradise. Toss, strip, FISH! That happened a whole bunch of times and I was very happy. Most of them were very photogenic and agreed to pose for a quick pic. I fished a little cut out of the wind and landed one of the biggest sunnies I ever caught. She was nice and chunky and pulled like a souped up John Deere. Just fantastic.

Marla and I had a great afternoon of kayak fishing and more than once she said how awesome my W700 looked and how much she liked it. Next time I might ley her try it out. When she does there just might be a two owner, green, sit-in kayak for sale here in Eastern North Carolina.
