Bungy®

Mounted easily and lightning fast on the rope, which does not need a free end but only a minimal slack. Fits ropes up to 20 mm (as well as straps).
Made of a weather-resistant rubber-like material, with extremely good stretching properties, which regains its shape without matting. The size of the boat determines how many Bungy are needed on each line. A large boat needs more Bungy than a smaller boat.

Bungy also works as a brilliant shock absorber on the big shot:
No problems with violent jerks and bangs when jerking
No problems with jerks under the bilge at bumpy lake
Advantages of bidewind sailing in gusty wind
Removed in seconds before racing.

Sold in 2-pack.
