12.9 Gennaker February 2013 Setting up and Sailing with the 12.9 Gennaker
12.9 Gennaker February 2013 Setting up and sailing with the 12.9 Gennaker The 12.9 Gennaker is a new bigger gennaker for the Weta. The standard gennaker is 8 sqm and the 12.9 gennaker is 12.9 sqm. The sail is designed for light to moderate breezes to help sailors racing in mixed fleets to get to a downwind mark faster. It is not intended to replace the standard 8.0 gennaker and will be sold as an extra. It is intended that one design racing fleets will stick with the 8.0 gennaker. It’s hard to say exactly what the performance difference in the sails is as it changes for different wind strengths. But with the 12.9 sqm gennaker you can sail on a generally lower (more downwind) heading than you can with the 8.0 sqm gennaker. The biggest changes are seen in a steady light breeze before you can get the boat planing. So to put it very roughly if you have two boats, one with the 8.0 and one with the 12.9 and you point both boats in a hot/tight reaching angle the 8.0 will be faster for most conditions. If you then point both boats at a low/broad reaching angle the 12.9 will be faster in most conditions. So on a windy day someone might sail further but faster with the 8.0 and get to the mark quicker than someone with the 12.9 sail who is sailing slower but less distance. For instance when Chris and I were testing, we did a day on a lake. -

Also, to hull structure or bulkhead, to which a shroud or stay direction 45 degrees abaft the beam. is attached. Shroud. Standing rigging that supports a mast laterally. Leeward (Loo’ard). Direction away from the wind, downwind. Stays. Standing rigging that supports a mast fore and aft. 1 The mast on a sailboat must either be strong enough to stand by itself under a full press of sail, or it must be supported by standing rigging. This section discusses shrouds, stays, and spreaders: the fundamental compo‑ nents of standing rigging, Figure 4–1. 2 A simple standing rigging, found on sailing dinghies, consists of two shrouds and a jibstay, Figure 4‑2. The ends of these supports typically have swaged terminals Jibstay Shrouds with an eye at the upper end and a turnbuckle stem at the Backstay Jibstay Upper Boom Shroud Crutch Lower Shrouds Figure 4–2 Simple Standing Rigging lower end. Swaging is a method of permanently attach‑ ing terminals to wire rope by deforming a steel sleeve to clamp it to a wire securely. The shrouds and stays are typically attached at the upper end to tangs that are a part of the mast, Figure 4‑3. The lower ends of the jibstay and shrouds connect to the stemhead fitting and shroud chain plates, respectively, through turnbuckles. Turnbuckles permit easy and precise adjustment of standing rigging, Figure 4–1 Standing Rigging Sail 28 4 – Standing Rigging Mast Ta ng Through Bolts Clevis Pin Swaged Fitting Shroud or Stay Cotter Pin Backstay Jibstay Figure 4–3 Shroud and Tang Assembly Shroud or Stay Swaged Fitting Right Hand Thread Tu rnbuckle Barrel Cotter Pins Left Hand Thread Marine Fork Clevis Pin Figure 4–5 Fractional Rig Sloop provide a better sail shape, is possible with a fractional Cotter Pin rig. -

Improving the Downwind Sail Design Process by Means of a Novel FSI Approach
Journal of Marine Science and Engineering Article Improving the Downwind Sail Design Process by Means of a Novel FSI Approach Antonino Cirello 1, Tommaso Ingrassia 1,*, Antonio Mancuso 1, Vincenzo Nigrelli 1 and Davide Tumino 2 1 Dipartimento di Ingegneria, Università degli Studi di Palermo, Viale delle Scienze, 90127 Palermo, Italy; [email protected] (A.C.); [email protected] (A.M.); [email protected] (V.N.) 2 Facoltà di Ingegneria e Architettura, Università degli Studi di Enna Kore, Cittadella Universitaria, 94100 Enna, Italy; [email protected] * Correspondence: [email protected] Abstract: The process of designing a sail can be a challenging task because of the difficulties in predicting the real aerodynamic performance. This is especially true in the case of downwind sails, where the evaluation of the real shapes and aerodynamic forces can be very complex because of turbulent and detached flows and the high-deformable behavior of structures. Of course, numerical methods are very useful and reliable tools to investigate sail performances, and their use, also as a result of the exponential growth of computational resources at a very low cost, is spreading more and more, even in not highly competitive fields. This paper presents a new methodology to support sail designers in evaluating and optimizing downwind sail performance and manufacturing. A new weakly coupled fluid–structure interaction (FSI) procedure has been developed to study downwind sails. The proposed method is parametric and automated and allows for investigating multiple kinds of sails under different sailing conditions. The study of a gennaker of a small sailing yacht is Citation: Cirello, A.; Ingrassia, T.; presented as a case study.
