Perimeter deck lines

Submitted by Rich Greenberg on Tue, 07/30/2019 - 15:26

Hi, I am new to this forum.  My wife and I have a couple of skin on frame kayaks.  They are beautiful and are built in a very traditional manner with no perimeter lines. As we venture out into Puget Sound more, I think I'd like to install perimeter lines.

Submitted by paradisepete on Sun, 06/09/2019 - 08:15

i am new to paddling and boat building.  currently building 2 sof canoes for the wife and i.  i run across from time to time videos from "mess abouts" or other gatherings where people gather to show the boats they have built and paddle around ect with other boat builders.  looking for events in the midwest region, although if there was a "can't miss" "super bowl"  event i would consider traveling farther.  any help or recommendations would be appreciated.  again brand new, so im sure i am not using the right terms. 

Modified lacing technique

Submitted by TomL35666 on Tue, 04/23/2019 - 13:30


I modified Tom Yost's lacing by looping the hull lacing over about 3/16" dia. trimmer line.  When the deck skin is complete, to remove the lacing, all you need to do is pull out the trimmer line and the lacing just falls away.

Skin around deck coaming

Submitted by TomL35666 on Tue, 04/02/2019 - 14:00

Has anyone tried to make a gasket around the coaming similar to the one used on the Trak 1600? I am skinning the deck on a somewhat modified Tom Yost kayak and would like to use a similar gasket around coaming. I am most interested in the type material used for the gasket.

Thanks, Tom

Glacier Bay - Alaska

Submitted by Sharli on Mon, 01/28/2019 - 19:44

I was wondering if anyone has tested the self-made kayaks in some weather conditions like in the Glacier Bay.

I found an article about Glacier Bay in Alaska and I am fascinated to do such a trip, If possible with a self-made watercraft.

I like the iqyax design, but do not have the right drawings. If anyone can assist I will appreciate it.

Willow Ribs

   Has anyone tried using willow or red dogwood shoots on a SOF kayak? Hillary Russell shows them in his book on building SOF Double Paddle Canoes. The technique interests me since I have seen some red dogwood growing along our local roads here in Greene County, NY.

Fast and stable flat-bottomed kayaks

Submitted by Rick.T on Wed, 11/21/2018 - 22:10

So, I’m about to start a new skin on frame kayak build, and I’m really fascinated with the Mackenzie River delta kayaks that the Inuvialuit built. I’ve never built one because money has been tight and I wasn’t sure if they would be a particularly useful rec boat. Then, I found a review of the Rockpool Taran 16, which seems to have a similar hull:

Thread for SOF

Submitted by frankp on Sun, 09/30/2018 - 23:15

I built a SOF kayak a while back that I skinned with a PVC skin.  Turns out that the way the skin fit the frame didn't allow me to get a good seal on all the seams and it took on a lot of water.  I was bilging every 15 minutes.  So, I've decided to reskin it with a nylon/polyester (not sure which) skin.  The skin is already treated and is incredibly light, I would say 6 or 7 ounces at most.  

Skin on frame: doubts about the fabric and lashing line

Submitted by Pfolha on Tue, 08/28/2018 - 21:07

Hello everybody,

I'm Brazilian and only found info to build a SOF in English and Spanish, I am facing difficulties in finding the recommended material, sometimes because no one sells locally, other times because I am lost in translation. So I have two questions:

  1. I only found ballistic nylon pre-coated with PVC, PU or Acrylic resin, which one should I choose? 
  2. What is "artificial sinew"? Is it a nylon line?

Thanks in advance,
