Is a higher VMG better?
At the optimum boat speed and angle to the wind, VMG is maximized, steering closer to the direction of the wind will reduce boat speed, while steering further away from the direction of the wind might give a higher boat speed, but at the cost of a larger deviation in heading, so less progress towards a mark.
What is VMG in yachting terms?
VMG stands for ‘Velocity Made Good‘. In simple terms, it measures the progress made towards the destination. The concept is useful because a sailboat often cannot, or should not, sail directly to a mark to reach it as quickly as possible. Yachts cannot sail directly upwind.
What is TWS and VMG?
TWS True Wind Speed. VMC Velocity Made Good (to Waypoint, course) VMG Velocity Made Good (to Wind)
What is a jibe in sailing?
Jibing – The opposite of tacking, this basic sailing maneuver refers to turning the stern of the boat through the wind so that the wind changes from one side of the boat to the other side. … Jibing is a less common technique than tacking, since it involves turning a boat directly into the wind.
How is VMG sailing calculated?
I plugged the numbers into this formula: (Boat speed at 8 degrees above dead downwind) x COS (the degrees above dead downwind) = VMG: 4.2 x COS (8) = 4.16 (VMG) (Boatspeed at 30 degrees above dead downwind) x COS (30) = VMG: 5.2 x COS (30) = 4.5 (VMG).
What is VMG in America’s Cup?
V – is for velocity made good or VMG, a complex equation needed because a boat often cannot, or should not, sail directly to a mark to reach it as quickly as possible. VMG is the optimal compromise between direction and speed towards a mark.
Can you sail downwind?
Upwind sailing requires a bit of precision. You have to keep your sails and boat on edge in order to make your way to windward. When you turn downwind, however, you can really cut loose!
