Tethered For Less

          I finally have time again for projects and one that I have had sitting for a while was my safety tether. I looked at grabbing some for a long trip last summer and they were crazy expensive.... I mean around $100-$200 for clips and nylon webbing. I don't know about you, but that's just crazy in my book. If I can trust my own splicing to hold my boat at anchor in a 30 knot blow on an open river, I think I'd trust my sewing machine and it's sail thread. Plus, why not make a cool custom tether that fits me?

          Well, I did just that. Components wise, I bought my webbing from Strapworks (I like their site, and if they want to pay me to advertise for them, I'd do it! [but they don't]), using 1" tubular polyester, which is stronger and more abrasion resistant than nylon, and 3/8" elastic. I also bought fancy ribbon on webbing for the quick release handles, 1ft each. I bought a lot... like 9ft of webbing in both colors (I built a pair of tethers) and 12ft of elastic. Then I found some climbing carabiners that had a permanent webbing loop, they are called "quick draws". I picked mine up from an english company and amazon and were $12-$14 shipped for each set (DMM is the manufacturer). I also saw a different brand at REI yesterday for $16, so they are easy enough to come by. Lastly, I picked up two quick release clip with rings on Ebay in an auction for $6 shipped, and I think they may have been used to airdrop tanks... but I'm ok with overkill. The total for supplies for two tethers came to just under $50.
5ft and 3ft hook
          The original design was to have 2 independent tethers coming off the central quick release clip, that would hook into your harness. This is what most of the 2-hook tethers have. I decided against that once I got everything situated, because I didn't want to be whacked with the second tether or have to have 2 hooked up all the time. So instead, I placed one hook at about 3ft and one at about 5ft. The 3ft tether is what I would use on the foredeck and the 5ft lets me go from the cockpit to the foredeck without ever being disconnected. I saw a video of folks testing tethers and decided shorter was better. The length will keep my on the boat even if I fall, not dragging in the water, which looks like a safe bet to me.

          As far as sewing is concerned, I just made sure to have 3 vertical and 3 horizontal zigzags securing every hook minimum. I also put some fun patterns in after the fact... because I could. First, I pulled the elastic through the webbing using a marker with the elastic trapped on one end in the cap. Then, I secured the elastic with a 2" zigzag stitch down the center, after pulling it tight so as to have it fully extended when initially sewn.  Finally, I sewed both clips at their desired length and cleaned up with the quick release. And that was about it, it took less then 30 mins a piece for each tether and the weakest part is the webbing, which is rated to 1800lbs... and I don't expect to survive anything that does that to my body anyway, so I'd say we are good to go.

Feeding the elastic

          As a side note now that I've completed the project, I think that using regular 1" polyester webbing without elastic is well worth it... the stretch vs non-stretch is less that 4" over the 5 foot length of my finished product (though the wobbly webbing does look cool).

Not too stretchy, but it looks cool

Building a Penguin 21 Sailboat

I said I'd show some boat photos from last weekends visit to Keith's shop, and here they are. Keith is about 6 months into his build, with all of the bulkheads up, and he put on the top plank (I'm not sure the official name of it) the week I visited. He plans on putting the bottom two planks on the boat, then finish the interior from outside the vessel, before finishing the planking. If you ask me, it looks like one hell of a boat!
