So, you are wide enough, but are you fast enough? Once you have practice skiing wide enough to consistently score Audio Slalom buoys, as described in the Audio Slalom Marking Your Boat post, it is time to start timing your passes.
Full Course Times
The following table provides the number of seconds it takes a boat to travel the full course at various kilometer per hour boat speeds. The times were derived from the IWWF disabled Rules, specifically D8.12: Audio Slalom: Scoring Imaginary Buoys.
| Boat Speed (kph) | Seconds |
| 58 | 16.16 |
| 55 | 17.04 |
| 52 | 18.13 |
| 49 | 19.27 |
| 46 | 20.56 |
| 43 | 22.03 |
| 40 | 23.74 |
| 37 | 25.73 |
| 34 | 28.08 |
| 31 | 30.90 |
| 28 | 34.37 |
Timing A Pass
Using 49K, you would have 19.27 seconds to complete a full pass. To time the pass:
First, a stopwatch needs to be started as you cross the right boat wake as you ski from the left side to right heading to buoy one.
Next, you ski wide enough to score all six buoys.
Finally, the stopwatch is ended when you cross the left boat wake as you ski from left to right after rounding buoy six.
If the stopwatch is at 20 seconds or less, you are probably skiing close to what it would take to score a full pass at 49K using an Audio Slalom Signal Generator (ASSG).
Ultimately, skiing sets using a CRONOS audio-slalom device, the official ASSG approved by the International Waterski & Wakeboard Federation (IWWF), will be required to take your audio slalom to the competitive level. In the meantime, hopefully the above full course times are helpful, and you will be out on the water practicing audio slalom soon.
Good Luck
