Watertight riveting in kayaks and boats

Updated October 6, 2017

Pop rivets are widely used in the construction of boats, canoes, and kayaks.
Sealing rivets can be useful as a measure of extra precaution in case they come in contact with the water through which your kayak or boat goes.

How to better seal the rivets

Here are some tips for watertight riveting of kayaks and small boats made from Polyethylene –

  1. Polyethylene is the most widely used polymer resin (namely “plastic”) in kayaks, and it’s softer than aluminum and fiberglass used to produce other small boats. For this reason, it is recommended to use special aluminum rivets designed for riveting jobs in kayaks. These special rivets split in three, which increases their grip on the surface around the rivet. You can get these rivets in outfitters stores, and online.
  2. Drill holes of exactly the same diameter of the rivet that you use (3/16″), and preferably slightly smaller holes (5/32″).
  3. Apply a dub of Goop adhesive on the hole, and push the Goop into the hole. Goop is a powerful watertight adhesive used for plumbing and marine projects. The Goop you squeeze into the hole will coat its sides, and come out on the other side.
  4. Before you insert the rivet into the hole, coat its end with Goop. As you push the rivet into the hole, its tip will come out on the other side, and it will be coated with a thick layer of Goop. The sides of the rivet will be coated with Goop as well.

    As you pull the rivet’s mandrel, the rivet will split in three and it will attach the two plastic walls while being coated with Goop. Excess Goop that will not come out on the other side or coat the sides of the hole, will remain on the outer surface and get squeezed by the rivet’s head. This way, the rivet’s parts that come in contact with the plastic will be coated with Goop, which will make them watertight.

  5. After you’re done riveting, coat the rivet’s head and the surface area around it with a generous amount of Goop. This will prevent water from touching the rivet, and in case of saltwater, it will prevent corrosion.

It wasn’t just about the fish

More from our trip to the Hebrides –

The W500 we took with us performed very well not just as a fishing boat, but also as a paddle craft for our family and friends.



The W went with us practically everywhere



Are we stranded? I don’t think it’s even possible with this kayak



This tandem crew doesn’t appear to be particularly alarmed by the situation



Should I paddle forward or backward?



The water here is so shallow – How about some poling?



Now I have this boat all to myself!



Don’t worry, I’ll be back



This place looks like the end of the world, and in a way it is



A second mother and son tandem kayaking crew!



This time with the motor mount in the right place

As far as fishing is concerned, here’s a video showing some of our local competitors:

W Kayak For Fishing and Bird Watching, by Russell Dodd, Western Australia

Due to back problems, conventional kayaks and canoes have become unusable for Russell, so he ordered a W500 for himself to paddle solo and in tandem with his wife Wendy:

It got a first run up the Canning River. Wendy & I got in straight up and pushed off – I must say it very stable and everything I expected it to be.
Paddling double up required some focus, as I am used to a Canadian Canoe which is what we used in Zimbabwe.
As a fishing and bird watching platform the W500 is certainly is a great unit. The bird watching from the kayak has been great.

Most of my focus has been directed towards sorting out a pulley harness to store the kayak in our garage roof and make it easy to load when we go out.
Also thinking about installing a forward mount electric trolling motor that’s foot controlled and leaves your hands free for other things – used to be great for bass fishing in Zimbabwe.

Everything is fine – have not used the kayak as much as I would have liked.
I am still taking things very slowly still.
Wendy and I have had 2 great trips on the sea out to Penguin Island and Seal Island just south of Rockingham which we loved. On the last trip I had a session standing and paddling on my own which certainly highlighted why I went for the W500, plus how much less drag there is opposed to carrying 2 up.
On Saturday I took a friend up the Canning which he loved.
Plans in April / May to go up to Denmark, 450kms south of Perth to test it on the inlets there & hopefully will get some photos for you.
The only photos I have taken to date are of mostly of birds and some of the seals and for that the W500 has proved to be wonderful – it gets you right into the zone. Within a year or 2 we should also get back up to the Ningaloo reef off Exmouth again which is what I really wanted the Kayak for – To get us out to the whales just on the edge of the reef and the fishing.
I have made up a roof extension frame to help load up the W500 onto our Grand Vitara roof – thanks to the good advice from your site and current project is to make some trolley wheels so I can manage on my own.
At least the w500 gets me into spots that are good for the soul.

Gary’s Seven Hour Kayak Fishing and Wildlife Observation Trip Report, Florida

Here’s a new report from Gary Rankel:

Was out for 7 hrs yesterday in hot weather and sun.

Ran into lots of redfish yesterday, but most were pretty spooky.

I did manage to get this beautiful 10 pounder on top water just as the sun was coming up.”

Also got a few sea trout and jack crevalle.

I just missed my “West Coast Slam” as a nice snook shook my topwater lure while airborne about 20 feet from the W (sorry I couldn’t snap a picture of that).
I also ran into a visitor who was really interested in your new W 500 (I think he thought he had just found the perfect mate). He entertained me for a good 20 minutes, repeatedly coming right to the side and of the W to get a good look.
