Incredible discovery whilst I was free diving off the coast of South Africa so lucky to find this jelly fish and get a close up of how it moves in the water and the beautiful colours it has on display. Free diving is an incredible hobby of mine and has taken me to places all across the globe. I feel incredibly lucky to have been able to see so many sea creatures up close. . . . .

UK Sailmakers uses very powerful 3-D CAD/CAM software for sail design, which create virtual 3-D molds that can be digitally sliced into two-dimensional panels that when joined back together re-create a full-size version of the designed mold. Thanks to powerful 3-D graphic renderings, designers can see how sail fit around the spreaders and shrouds as well as make sure the clew height and sheeting angles are right. They can also analyze how a main and genoa work together to make sure the boat stays balanced. What we are looking for is a sailplan and sail shapes that put the maximum driving force in precisely the right place to produce a perfectly balanced boat – and with the least amount of drag. Pat Considine, UK Sailmakers’ chief designer, goes a step further and uses Fluid Structural Interaction software, called FSI for short, as a virtual wind tunnel for refining sail designs and sail construction. FSI calculations are used to test proposed designs and cloth choices to make sure they are not built too strong (too heavy) or too weak (too light) for their expected loads. The FSI calculations will predict whether a design and construction will keep its shape properly as the rig bends, halyards are tightened and sheets are trimmed. Shown rotating in this video are two renderings of a Tripp 47 mainsail design. The side-by-side comparison shows the sail with no backstay tension and with max backstay trim. The FSI software allows Pat to rotate the two designs together to study their shape from any angle. In this case, Pat needed to be sure the draft would not move too far aft as the sail was flattened; likewise, he had to make sure the draft was not too far forward when the backstay was eased completely. The FSI program has made extremely accurate predictions of how specific sail designs will perform once made and trimmed in a variety of wind speeds. These tests ensure sails will meet the performance needs right out of the bag.

Le constructeur canadien de motomarines Sea-Doo (BRP) s'associe à Senna Brand pour rendre hommage à l'héritage intemporel d'Ayrton Senna avec une édition limitée exclusive. Le RXP-X Senna 350 présente des éléments de design exclusifs inspirés du légendaire pilote F1. La signature emblématique d’Ayrton Senna est gravée au laser sur la motomarine, aux côtés d’une mention de ses 3 titres de champion du monde. Une plaque portant le numéro 1991 rend hommage à son dernier titre de champion du monde. Grâce à un procédé de coloration hautement exclusif, le RXP-X Senna 350 a été méticuleusement conçu pour reproduire fidèlement le casque de course original de Senna. Son moteur Rotax 1630 ACE offre une puissance de 350 chevaux et une accélération de 0 à 100 km/h 15 % plus rapide que celle des modèles précédents ! Le RXP-X Senna 350 est une production limitée et exclusive de seulement 1 991 motomarines uniques dans le monde entier !
