Hi Goran from Croatia.
Welcome for the café. You mention Yamaha 280, but is it alto/tenor?
Where in Croatia are you?
I sailed through the islands in the late 70s. From Mali Lošinj to Dubrovnik. We failed to stop at Šibenik for reasons I can't remember. I was a teenager then and all that mattered to me was sailing.
One of my best memories of a thunder storm dates from that cruise. It was at night between some of the islands. The flashes of light illuminated the surrounding coasts and it was fantastic!
