Fast, One-Handed Rescue Kit
The Palm Lightning is an 18m throwline designed around one problem: rescue kit has to work under pressure, with cold or gloved hands, on the first attempt. Every retailer stocks the same core rope-and-bag spec, so what actually matters when you're choosing a throwline is how fast you can get it open, thrown and repacked — and that's where the Lightning's construction earns its place in Palm's range.
Fidlock Closure and a Chalk-Bag-Style Neck
The bag closes with a Fidlock magnetic buckle — a thumb-open, snap-shut mechanism that's faster and more reliable one-handed than a drawcord or Velcro flap, especially with wet or cold hands. The neck itself is stiffened in the same way a chalk bag is, so it stays open on its own after you've pulled it, making repacking the rope after a throw noticeably quicker than with a bag that collapses shut.
Built for Moving Water Rescue
This is whitewater and moving-water rescue kit, not general paddling gear — it belongs in a rescue kit alongside a buoyancy aid and appropriate river-running equipment, not as a standalone safety solution. It's built to deliver a single rescue throw and be recoiled, not for repeated hauling or load-bearing use.
Who It's For
The Lightning suits paddlers building or upgrading a personal rescue kit — moving-water kayakers and open-canoeists who want a compact throwline they'll actually carry, plus clubs and instructors restocking group kit. If you're new to carrying rescue equipment: owning a throw bag isn't the same as knowing how to use one safely. A swiftwater or whitewater rescue course will teach safe throwing, retrieval and swimmer contact — treat this page as kit, not training.
Rope, Bag and Breaking Strain
The rope itself is 8mm floating polypropylene kernmantle, rated to 8kN static breaking strength, packed into a Cordura 500D bag with a 420D polyester lining. That 8kN figure is a rope-safety spec, not a guarantee: it's the load rating for the rope as a throw/rescue line specifically, tested on new, undamaged rope — it is not the same class of rope used in mechanical-advantage hauling systems, which typically run to a higher rating on a larger diameter. Age, UV exposure, sand ingress and knotting all reduce the effective strength below that figure, so inspect the rope before every trip and retire it if it shows wear.
Not a Tow Line
A throwline is built to pay out loosely for a clean, controlled throw — it isn't rated or built for the sustained tension of towing another boat. If you need to tow, that is a different job for a dedicated tow line or tow-belt system such as the Palm Quick Tow Belt, not this kit.
Getting the Right Length
18m covers most river-width rescue throws in a bag that stays compact and easy to carry. If you regularly paddle wider water and want 2m more reach with 11mm, 10kN rope, the Palm Bolt 20m Throwline is better suited. If you need to select from 15m, 20m or 25m lengths and want built-in flotation for repeated throw-and-repack use, choose the Palm Pro Throwline.

Frequently Asked Questions
What does the 8kN breaking strain actually mean?
The 8kN figure is the static breaking strain of the rope when new, tested as a throw/rescue-line spec. It's not the same class of rating as the rope used in mechanical-advantage hauling systems, so treat it as a rescue-throw spec rather than a rigging spec, and remember that age, UV exposure and sand reduce it below the stated figure over time.
Is 18m long enough for a throwline?
18m is a solid working length for most river-width rescue throws and keeps the bag compact to carry. If you paddle wider rivers or want 2m more reach with 11mm, 10kN rope, the Palm Bolt 20m Throwline is better suited. If you need a choice of 15m, 20m or 25m lengths with built-in flotation for repeat use, choose the Palm Pro Throwline.
What's the difference between the Palm Lightning and the Palm Bolt 20m Throwline?
Both use Fidlock closures and Cordura bags, but their rope specifications differ. Lightning is an 18m, 8mm throwline rated to 8kN; the Palm Bolt 20m Throwline has 20m of 11mm rope rated to 10kN. Choose Bolt when the extra 2m, larger-diameter rope and higher static breaking-strain rating suit your rescue-kit role better; choose Lightning when its 18m, throw-first specification is the better fit.
Can I use the Palm Lightning as a tow line instead of buying a separate tow line?
No — a throwline like the Lightning is built to pay out loosely for a rescue throw, not for the controlled, continuous tension of towing. For towing, you need a dedicated tow line or tow belt system instead.
Do I need training to use a throw bag safely?
Yes, in practice — a throw bag is only as effective as the technique behind it. If you're new to rescue kit, a swiftwater or whitewater rescue course will teach safe throwing, retrieval and swimmer contact before you rely on this kit for real.
