The slings were there from what I believe was a first attempt to
rescue the boat. After I took those pics the boat remained there for 2 more weeks, with the slings and everything else on (it seems nobody took anything from the boat -
sails were in good condition, ropes,
solar panel etc).
I don't know how they put the boat on the
water because I missed that moment. When I got to the beach the boat was still aground but over the
water and they spent like 2 hours trying to pull her with the help of a small fishermen's boat

. Only then a bigger and powerful boat joined the
rescue operations.
