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.

► Full article in MW194: https://www.multihulls-world.com/information-catamaran-charter/caribbean/saint-lucia-a-stopover-not-to-be-missed-saint-lucia ► For a long time, the organizers of the ARC were faced with difficulties regarding the reception of multihulls: in a port, the latter obviously take up more space than the monohulls... In the end, the general success of this transatlantic -supervised rally and the ever more pressing demand from owners of catamarans and trimarans led the World Cruising Club to organize a second rally – the ARC + –, then a third – the ARC January. As a result, since the pressure on marinas has subsided, there have been more multihulls every year: there were 33 at the start of the ARC "historic canal" in 2022, 37 last year and 44 this year - we have them found in Saint Lucia in the Rodney Bay marina! ► 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!
