^^ yes correct, at low tide we just sail between anse vata and "Ile aux canards" nice flat spot to jibe and head back to the beach.
Yes 4 to 5 km would be the distance, between ile au canards and the spot you come across quite large waves which make the crossing a bit more exciting !!
Best time of year is from october to march, 15 to 25 kts on a regular basis.
The anse vata beach has three rental outlets : naish center, aloha (starboard/jp/NP) and sp8ce (loft/rrd)
Gear going from beginners to free ride, Sp8ce would hire you top end gear if they see you can handle it
