for a given value of true
The weather forecast was for 15-20kn's. This has turned out to be true.
For a given value of true.
Currently, as near as I can figure, rounded up, allowing for boat speed and subejectivly I'd have to say we had none. Therefore the given vaue of true is:
"Average of really light bits and 40knot gorrey death with pleasant* periods of gale force 8 boat cleaning hozizontal rain from a random direction"
Its not that the forecast is wrong - its just missleading.
* for a given value of pleasant, in this case its the same one that formular 1 bloke likes - sadomasocistic.
