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.

Come procedono i lavori? Come vanno le cose? Ma soprattutto… ha smesso di piovere da voi? 😂 Il giorno del varo si avvicina, il giorno in cui torneremo in acqua. Come stiamo riuscendo a gestire lavoro al pc e lavori in barca onestamente non lo sappiamo neanche noi. E non è che lavoriamo due orette e per la giornata siamo a posto 😄 Arriviamo a fine giornata esausti, ci si chiudono gli occhi e appena tocchiamo il letto crolliamo a dormire (zanzare permettendo). Ma siamo soddisfatti. È gratificante prendersi cura di qualcosa e vedere che migliora giorno dopo giorno. Con la testa siamo già in mezzo all’oceano, tra le onde che inghiottono l’orizzonte ad avvistare delfini e balene, a ospitare uccelli che si sono persi, a guardare l’infinito e sentirci completi. Sento che la fine del viaggio si avvicina e non sono ancora pronta. Vorrei afferrare il tempo e tirarlo fino a farlo rallentare, per scacciare questa sgradevole sensazione di affanno per le cose che non stiamo vivendo, per i luoghi che non stiamo scoprendo, per le ore trascorse al computer. Poi però respiro e mi ricordo che va bene così. La vita, come il vento, è tutta una questione di punti di vista. A domani ✨ Camilla

This one did not go to plan. Rather than follow the crowd and go along with the Sail to Indonesia Rally fleet to Banda Nera, we intended to day hop along a series of islands from Kei Kecil to explore the remote and seldom visited northern coast of Seram in north western Indonesia but the weather didn’t play the game. After a first night stop at Pulau Kur where we were unexpectedly met by machete wielding youths, we struck out north for a short passage to an island where we had identified three likely looking anchorages. Unfortunately the wind and swell conspired against us making all of them untenable, so we elected to sail on through the night to a Plan B but, when it and then Plan C also didn’t work out, we were forced into coming up with a plan D. When we did finally find shelter add in getting summoned by local officials and having Police onboard and this episode makes for an interesting tale. We hope you enjoy it.
