WebAug 10, 2024 · 3) TP52s do big numbers upwind relative to wind speed. 9.3 or 9.5. At this speed relative to wind speed the apparent wind angle closes down rapidly and TWA is limited. An old 12m went much slower relative to wind speed hence could probably manage tighter TWA values for similar AWA values. WebThe sail is intended for angles between 110° TWA to 145° TWA in wind speeds between 15 knots-25 knots TWS. To make it perform well at these angles and wind speeds the girths are slightly smaller than on your full size runner. Also the head angle is slightly reduced to make the sail forgiving when you sail at high angles. Size factor: 80% of S2. ip office hold music

WebLoosely defined, apparent wind is the wind we feel and experience when we are in motion. It's a combination of the actual wind (true wind) that blows over land and sea and the wind created by our moving forward. The popular analogy is that of riding a bike. Get on a bike and start pedaling. WebThe angle between AW and BV, shown as ^aw, is 53 degrees. The apparent wind, therefore, has a speed of 25 knots coming from a direction 53 degrees south of east. It is the … The recognized points of sail are in reference to the true wind direction, as indicated by a fixed wind indicator (flag, windsock, etc.), and encompass: • Into the wind where a sailing craft is pointed directly upwind in the middle of the no-go zone, where sails cannot generate power. • Close-hauled where a craft is sailing as close to the wind as its sails can generate lift (like a wing) to powe… ip office iii
