Pulk features

Laminated shells (fibreglass or Kevlar) – simple, strong design, fit for purpose.

  • manufactured by vacuum process, to give ideal fabric to resin ratio, producing mouldings of the highest strength.
  • rounded egg-shaped front and gentle ‘attack’ angle helps deflect impacts and reduce stress.
  • ‘rocker keels’ (slightly convex along length) on pulks 2.0 m and longer makes turning  easier.

Fibreglass – good impact resistance and loading ratios (maximum payload:unladen weight) of around 12:1, using over 80% woven fabrics.   Heavier than Kevlar.

Kevlar – the ultimate for high performance, with loading ratios of up to 18:1. Made to order, and reinforced in key areas to produce the flexing characteristics required for the particular activity.

Where kite traction is intended, Kevlar is recommended because of high travel speeds and consequent high impact stresses on the laminated shells. Kevlar is also recommended for travel through pack-ice.

NB. In real-life situations, particularly where the absolute priorities of low weight and high impact resistance are compromised, pulks can never be guaranteed completely damage-proof. As always, the end-user is responsible for how they are used, and must exercise due care. And to state the obvious, pulks are NOT designed for hauling over moraine/rocks/runways, etc-plastic runners and gel coats scratch very easily, resulting in increased friction and greatly increased wear.

Runners – machined from ultra high molecular weight (UHMW) polyethylene (for use well below -40C). The face of the runner is completely smooth (except for bolt at the front), and can be slid off for replacement.

The support rails for the runners are located in a groove in the runner keels, to resist sideway impact. They are either riveted or bolted, depending on their need for waterproofness.

Covers

  • high tenacity, proofed and UV-inhibited Nylon fabric.
  • Nylon adjustable webbing straps.
  • full length heavy duty YKK zips, two sliders and pulls, opening from the centre for easy access and packing.
  • lifting handles at each end and two either side, all bolted to the pulk shell.
