That first offshore photo looks pretty windy, Greece is windy alright, especially eagean sea.
5.7 and 6.7 sails require outside back foot straps, so you can think your big board for these sails. Although you can keep you existing Kode, 100lt range would be better.
For small board you should have single back foot strap. In my opinion, for lightweight people, 85lt is about max to have easy leverage at back foot (single strap), i guess depending mostly on tail width. Thats why i would suggest 85lt multifin to use with small sails (<5.5). It may be a bit difficult at first but you will get used to it.
Later you can upgrade your big board with a smaller size freeride or freerace baord.
