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.

Questa mattina ci siamo alzati e sembravamo tutti camminare a un metro da terra. Finalmente partiamo! Certo, le Canarie non sono al di là dell’oceano, ma comunque rappresentano il trasferimento più lungo mai percorso finora. 4/5 giorni e 600 miglia circa. Oltretutto l’equipaggio è riunito e siamo tutti affiatati. Assisto divertita ai piccoli balletti che nascono quando due abitudini casalinghe diametralmente opposte si incontrano e in qualche modo si deve arrivare a una soluzione che accontenti tutti. Prendiamo la moka per esempio. (Gli italiani e il caffè, esempio non casuale 😂). Chi normalmente la lascia “sporca” perché così s’impregna di aroma. Chi normalmente la lava subito per mantenere l’ordine. A bordo la priorità è mantenere un clima disteso e sereno, perciò è praticamente impossibile che ci sia un tira e molla per questioni come queste. Ma io vedo i piccoli gesti e le piccole espressioni e me la rido sotto i baffi mentre le relazioni prendono forma a pochi metri dall’oceano. Camilla
