The ROKKER is born august 2020 as a new kite in between ROKKAKU and Pearson ROLLER
The ROKKER shows several construction details quite similar to ROKKAKU The ROKKER is a very stable kite, suitable for KAP activity and covering a wind speed range quite wide ; in the standard configuration it is from 4 to 40 km/h and there are good chances to make bigger /light kites extending to lower wind speed or smaller and heavy sail that are covering higher wind speeds if for example during a KAP session the wind is increasing speed the ROKKER has a self adaptive configuration and keeps flying at good angle without pulling too much (while ROKKAKUs in this conditions are pulling very hard with risk of a frame damage and line angle is quite reduced...).
The ROKKER shows two overlapped sails :
The airflow from main sail is flowing at a good high speed on the back of lower sail and the result is a change of kite inclination
The MAIN-UPPER sail is similar to ROKKAKU construction but lower edge is straight and reinfoced at the back by 6-8 cm of mylar with carbon fibers or another low elasticity material heavier than sail
The LOWER sail has a tubular shape on horizontal upper edge in order to hold the lower bowed spar. The sail needs to be sewn over the main-upper sail overlapping flat on flat for near 4 cm ; sewings about 10 cm each side over and under spar tubular ; in the middle of the kite sewings extended about 12-14 cm centered to mid line
Spine pockets, upper horizontal spar, bridles and bow tensioners are equal to ROKKAKU
