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...

► Full test in Multihulls World N°193. ► The Gunboat 72 had its first official presentation at Cannes, and was impossible to miss, with its mast towering over 100 feet (30 meters) above the carpeted pontoons! Slightly longer and beamier than the Gunboat 68 (a model approaching the end of its career), the new catamaran also boasts a larger nacelle and, above all, a vast flybridge - a first! The aim is to introduce a comfortable, fast and luxurious multiyacht into the Gunboat family. Obviously, the 72 remains a high-performance catamaran, capable of sailing at wind speed from 8 knots. Compared to the speedy 68, it weighs over 10 tons, despite extreme care in the choice of materials and build quality... but the sail plan gives the impression of being more powerful than that of the Gunboat 68 Racing – 3,100 square feet (288 m²) upwind versus 2,712 sq ft (252 m²), and 4,844 sq ft (450 m²) downwind versus 4,682 sq ft (435 m²). Note that accommodation layouts are designed according to the owner’s wishes. ► Technical specifications: Builder: Gunboat Length: 72’2” (22 m) Waterline length: 72’2” (22 m) Beam: 30’10” (9.4 m) Draft: 5’7”/12’6” (1.7/3.8 m) Air draft: 106’2” (32.37 m) Light displacement: 62,600 lbs (28.4 t) Loaded displacement: 71,650 lbs (32.5 t) Mainsail area: 1,830 sq ft (170 m²) Solent: 1,270 sq ft (118 m²) A3 Spinnaker: 3,014 sq ft (280 m²) Fuel: 343 US gal (1,300 l) Water: 222 US gal (840 l) ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 500 multihulls tests!
