With winter comes bigger waves.  Having broken my leash several times I am now interested in a better leash design.
 
Does anyone know where to source the 5/16”, 11/32” or larger diameter surfing grade polyurethane cord?
 
I have been having a very difficult time finding the source for polyurethane leash material on the web.  I found one type that appears to be close, but slightly softer and more stretchy.  I would assume that this material could be acquired easily but haven’t found any immediate sources.

I asked the same question 7 years ago and have never found an answer or a source.

Wetstuff provided me with a 200' roll of the red cord that I have been using for more than 5 years to make my leashes.

Umm, seriously? Google it. Polyurethane cord is used as a belt for power transmission. You can get it from McMaster-Carr or a zillion other places.

I gave up hunting years ago.  Googled it, bought the stuff from McMaster Carr.  It was more elastic than typical leash material.  Felt more like a rubber band.  I agree this stuff should be widely available but it is hard to find in bulk with the right elastic profile, durometer hardness, uv resistance . .

Winter coming. The surf here on the west coast of Vancouver Island has been big the last couple of weeks. In the summer I broke a leash plug on my Speeed and had it replaced. Decided to add a back up stick on leash plug. Today shoulder to head high and broke a leash. Good time take a close look at all my safety gear. I use Leash Lok Hawaii waist leashes. The leash was perhaps 2 years old. The swim in was only a couple of hundred meters and no drama. There were perhaps 60 surfers in the water and fortunately my board didn’t hit anyone on its way to shore. I was the only SUP surfer out. Amazing how popular surfing has become during the pandemic.

Try Samson, AmSteel-Blue Rope is a Dyneema HMPE fiber in a 12-Strand Single Braid a 18" diameter breaking strength is 2,300 lbs - it is used on boats and UV resistant and more cut resistant than nylon. I have it as the leash rope loop to my boards.
Also make sure to round the edges on the factory plugs to get rid of the sharp edges.
I found Dakine has a big wave leash 7/16"x 12' with a  2year warranty https://www.dakine.com/products/peahi-12-7-16-surf-leash-w-clip - for the less handy foiler

Thanks Finbox

That Dakine leash looks robust at 11 mm thick! My heaviest Leashlok is 9 mm and the leash I broke is 8 mm. If I break the 9 mm leash I will try the Dakine. I can't imagine that I could break that leash. I am not a big guy but the forces generated on these large boards must be huge.

If you need an on-the-water leash repair - learn to tie a double-uni knot or blood knot (can use 2 wraps instead of 4).  Both work well to keep you going if you have a long enough leash to start.  I've done this a half dozen times over the years.   

I am now making my own leashes but have never found the right cord-stock.  And no, you can't buy the right stuff on mcmaster carr.  If anyone finds a source for good stock, please let me know.  I buy 9 or 10ft leashes .313" or 8mm and cut off the ends.  So far the XM have been working the best - the cord itself is extruded in their factory in San Clemente.

To make your own hand tied leashes, the double sheet bend works great.  I use 6mm parachute cord doubled up to make a loop on both ends.  This picture shows how the knot looks.  I wrap some electrical tape around afterwards to clean it up.

Thanks Jondrums

I tried the double-uni knot for joining the broken 8mm leash ends. It is not pretty but it did work. It took about 1.5-2 feet off the length of the leash. When my leash broke the board headed to shore leaving me to swim but if I was surfing on a reef I might have been able to collect the board and join the broken ends. 

Cheers

Oh - cool.  That knot totally works, but I guess I didn't know the exact name for what I'm using.  A double overhand knot maybe would be a better way to describe it - takes quite a bit less leash length.

I broke a leash on a huge day at Ocean Beach and luckily got to my board pretty quick.  I tried grabbing a wave in and wiped out only to lost my board again.  So instead I paddled back outside and sat on the board and made this repair.  It worked well enough that I decided to stay out a while longer and then surfed it for the next month on smaller days.  I've used the same knot a handful of times to rescue a session.

Here's a pic of the exact knot that saved me at big OB, cinches up tight and holds.

Yeah, I'm a knot nerd.  I taught knot tying for boy scouts as a camp counselor for a couple summers.
