Hi, I would like to buy my first windsurf equipment, I have a intermediate level, 67 kg and 170 m.
I live in a very windy area and ride mainly in fjord (2-3 meter deep)
What type of board and sail would be best for me to buy ?
Thank

Love to help Thors but it's a bit hard from here, are there any other local sailors, you'd be better off asking them.
If not how windy is "very windy", and what is "intermediate level", are you in the footstraps and harness, can you water start and gybe?

If all of the above is yes, then possibly a free ride board between 70l and 100l and a free ride sail between 4.0 and 6.0m depending on how strong "very windy" is.
Around 20kts a 5.5 should be OK, 30kts perhaps a 4.5. If more than 30kts then go for the 70l board or less and a 4.0 sail
