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...

A quick view of hoisting and dousing the spinnaker of the RS Feva sailing dinghy, which is super simple to raise and lower. Find out more about the RS Feva here: https://westcoastsailing.net/rs-feva
