POWERKOTE

Product catalog summary

Overview
Powerkote is a specialized range of nylon spinnaker fabrics designed for asymmetrical spinnakers used on modern light displacement yachts, dinghies, and catamarans. It is based on warp-oriented constructions similar to Superkote but features a newly developed PU coating that is 25% more stable, allowing for better draft maintenance under high loads. Compared to polyester fabrics, Powerkote is less sensitive to shock loadings.

Specifications
The Powerkote range includes various styles with specific weight and strength characteristics, allowing for optimal strength-to-weight ratios. The styles include PK 55, PK 66, PK 77, PK 78, PK 88, PK 99, and PK 133, each with different warp and fill constructions and breaking loads.

Technical Specifications

PK 55: 0.82 sm. oz. / 35 g/m², 30 x 30 warp x fill, 45 kg breaking load
PK 66: 0.89 sm. oz. / 38 g/m², 30 x 20 warp x fill, 46 kg breaking load
PK 77: 0.94 sm. oz. / 40 g/m², 30 x 30 warp x fill, 46 kg breaking load
PK 78: 1.03 sm. oz. / 44 g/m², 30 x 30 warp x fill, 48 kg breaking load
PK 88: 1.05 sm. oz. / 45 g/m², 30 x 30 warp x fill, 55 kg breaking load
PK 99: 1.17 sm. oz. / 50 g/m², 30 x 40 warp x fill, 60 kg breaking load
PK 133: 1.43 sm. oz. / 61 g/m², 70 x 50 warp x fill, 75 kg breaking load

POWERKOTE Extra firm PU coated nylon: for more power on beam reach courses Powerkote is an especially designed range of nylon pinnaker abrics that meets the specific performance s f requirements of symmetrical spinnakers, on the latest generation light displacement yachts, dinghies a and catamarans. Powerkote is based on the same warp oriented constructions as Superkote. This combined with P owerkote’s newly developed PU coating, which is 25 percent more stable than the finish of Superkote, enables ailmakers to produce spinnakers that keep their draft forward better, even when highly loaded. s In omparison to polyester spinnaker fabrics Powerkote is less sensitive for shock loadings in the sail. c As with all the product ranges of Contenders spinnaker fabrics the gradual steps in weight, strength and diagonal stability are designed so that weights of the different styles can be combined, to achieve the best strength to weight ratio for the sail. ≥≥ Powerkote - Technical specs Style
