Navigability index · Sidi Bou Saïd
Indicative only: the same bulletin reads differently in a fishing boat, a cruising yacht or on a kite. It does not replace the official bulletin or your own judgement on site.
Small boat: waves, gusts and short chop all count.
Sailboat or motor cruiser: a gale sets the limit.
You need wind, but steady. Check it isn't blowing offshore: it would carry you out to sea.
