It really depends on the boat size and at what speed you want to sail. In just a light breeze the yacht will be moving and then as the wind increases strength the yacht will start going faster. I sailed a Vivacity 20 and a Halcat and this is what I experienced. Any other comments welcome.

Below 5 knots of wind there is not a lot of fun to be had, unless you are a fanatic or want to enjoy drifting!
At 10 knots of wind things are pretty good for a beginner.
At 20 knots of wind you need to be skilled and experienced and diligent.
At 35 knots of wind there is a saying
- you don't need a life jacket, you need a priest.
Most kinds of races are cancelled if there is not at least 5 knots of wind at all the buoys.
A lot of this is influenced greatly by the surf, boat and mood of the sailor.

Typically, wind turbines need a minimum wind speed of about 6-9 mph (3-4 m/s) to generate electricity. This is known as the cut-in speed. At this speed, the turbine blades start rotating and generating power.
It depends on the speed of the vessel, the wind speed, the place and how choppy it is.

60 knots is the minimum speed for a wind aloft to be termed as a jet stream..
The minimum wind speed for a hurricane is 74 mph.
The minimum wind speed for a storm to be considered a hurricane is 74 mph.
No, the pressure in the sails does not increase by 8 times when the wind doubles. The pressure in the sails is directly proportional to the square of the wind speed increase. So, if the wind speed doubles, the pressure in the sails will increase four times, not eight times.
5mph
74-95 mph.
32 MPH
a sail boat can go twice the speed of the wind in optimal conditions. speedboat 30-40
