Gun dual plug leash installation

[nizhogor]

Finally got myself a gun for bigger days along with Dakine Peahi Leash. The board is dual plug, the leash is dual string, but I am not sure what's the best way to tie knots and arrange strings. Probably just in parallel for each end of rail guard. Also strings have inner cord which sticks out of the outer cord. I assume you need to use a lighter to burn the edge of the inner cord to make it more solid after tiying a knot, but not sure how much of inner cord I need to pull out before doing that. Any advice/image share of your setup? To my surprise searched the Internets without luck.

How big are the waves you are surfing? I just got a gun with dual plugs and didn't even think about it. I just figure you need to check and if one of the cords break then replace it before you go out again. I'm not currently planning on going out in huge waves maybe triple overhead at the biggest so probably don't even need it. I know nothing about the inner cord thing. Mine are just tied.

Two plugs are there for a reason. Rented a gun in Hawaii when it was 15-20' according to Surfline. First big wave attempt for me. That's where I noticed a dual plug setup. It was a year ago and I don't remember the exact wiring, but I noted that both plugs were utilized. Even when surfing 5-6'+ I would imaging routing is crucial. If you bail/fall on such a wave at a speed a single cord is holding a board while it's being pulled by a wave in opposite direction. That's how one rips a string or pulls an entire plug out. That being said if waves are weaker it might be ok, but I personally wouldn't risk it.

I probably only go out in 9 foot waves at the biggest maybe 10 foot. I think it's a good idea but my boards are not off the shelf boards , they are all custom made and fairly durable. I guess maybe I am just lucky but then I haven't been out in 15 to 20 foot many times (3 times total) and that was long ago. I am an old man now not into the big stuff so much preferring overhead to double overhead. I got the gun just because I am getting old and figured the extra flotation might be good as I get older. In my imagination the way the double plug works is one cord will break but the other will stay intact and then you can get your board and replace the broken cord when you get in.

Interesting, I would think each plug gets it’s own rope. But here this guys set up is a long leash rope going through both plugs.

Yes, I've also found www.standupzone.com/forum/index.php/topic,13848.0.html#msg121198 as well. Dunno if it's any different for SUP. Shouldn't be really. Still, I would expect both strings being used.

That would be good to keep the plug from puling out but still only break 1 cord and lose board

Im no big math head or big wave surfer but sling loads for a living and fix gear rock climbing . The load principle is the same.
The inclusive angle at the point where two equal length leash cord loops meet at the rail saver on the leash must be less than 90 degrees to have any real benefit. At this point of reading make an angle shape between thumb and fore finger. Closer the fingers together the more they share a pull loading. At 90 degrees the load/ pull force is 0.7 factor of the original pull force. At angles greater than 120 degrees the load factor increases to amounts greater than the actual load, to mean you are at that point you are over loading the leash plug more than if you where just attach with a single leash core.

So if your leash plugs are far apart your ideal set up of the leash cord length is long enough to keep the angle less than 90 degrees, but still allowing the rail saver to do its job and the leash not to be able to pull over a the pin tail of the board. Where the shaper puts the leash plugs is a place that has high strenth glass and either equidistant to the central wood strnger or in epoxy stringerless boards area with high density foam and clever lay up fiber mat weave.

It will probably mean that leash cord sold at surf shops will not be long enough to make loops. Excellent custom cord can be made from 5mm diameter dyneema core sailing rope. Hard wearing, high strength, low stretch flexible and salt restant . Climbers use its average brake strain 1200 kg.Purchase by the meter/yard Cut to length with hot knife and finish with std overhand knot. Worth making ends into little blobs that will not pull through the knot as a safety.

I only own one duel plug board. It's a 14 ft x26 gun shaped sup for big fat swells, but it's big and heavy at 12.5kg. I spoke to hawaian shaper Ian foo of hypr hawai for his advise.

LOL. So two cords, one for each plug or one cord looped through two plugs?

FWIW I tie leash cords like this, leave the ends long and trim then burn with at least 3cm of cord sticking out each side so the knot won’t work free. The harder you pull on a cord tied like this the tighter the knot gets, but pull the loose ends and it’s easy to undo the knot.

I saw this too; load angle ratings fir double plug setups.
