I recently bought a Vega (Hull number below 100, but don't remember exact),
and I got a speed diagram with it. The speeds reported where:
Windspeed, 8 m/s
Nr Angel Speed Effective speed in direction of wind
1 21,0 2,4 2,2
2 27,6 3,4 3,0
3 35,6 4,5 3,6
4 42,6 5,2 3,8 Optimal height
5 51,8 5,3 3,3
6 58,5 5,5 2,9
7 64,5 5,8 2,5
8 77,2 5,9 1,3
9 100,0 6,8 1,2 Topspeed (surfing)*
10 111,0 6,2 2,2
11 136,4 5,9 4,3
12 172,8 5,14 5,10 Optimal lens
* this point should not be used in interpolations
Vessel speeds in knots
My questions are:
- does anyone know if this diagram is for vessels with or without spinnaker?
- what will the vessel speed be for other wind speeds?
There where also included a stabillity diagram. Koefficient were 10 for 45
deg tilt.
What does this mean?
