When developing the Element line, Harken engineers first stared at this question: How do you deliver Harken design quality at a price competitive with other “value price” products already on the market? The answer is in the name—Element. Harken engineers stripped away everything that wasn’t a building block of durability or strength. Then they combined a proven bearing system with the strength of forged aluminum sculpted to protect the fiber-reinforced nylon sheave. The result is a contemporary, economical, and extraordinarily durable block. Element is for all sailors, whether they’re cruising the bay, rendezvousing with friends, competing in the weeknight beer can race, or embarking on a passage-making adventure.

Volando el Rokit en el Juancarlos... Sólo 0,5L En otros lanzamientos con botellas de 2L tuvimos grandes problemas de estabilidad. El cuerpo estrecho de la botella de 0,5L parece funcionar mucho mejor. También se ha observado una mejor estabilidad de la botella de Fanta frente a la de Cocacola. Quiza debido a que el estrangulamiento evita que el agua trepe por las paredes, o quiza incluso por un efecto coanda (?)... Flying the Rokit on the Juan Carlos I park in Madrid. As previous flights with 2L bottles were highly unstable, we took here a narrower 0,5L Fanta bottle, wich performed much better. The performing has been observed to be better also against 0,5L Coke bottles, which could be due to the water not rising through the walls of the rocket because of the throat of the Fanta bottle, or maybe even (?) due to a coanda effect...
