Suddenly they appeared in front of our boat: dolphins! They are magical animals to me, suddenly they jump in front of your boat. But only for a few minutes. They swim with you, zigzagging, diving down, jumping above the water again and then they're gone. This was at the end of February, when we made a 'turn' at the heel of southern Italy, Puglia to sail into the Adriatic Sea, towards Lecce. I was able to film the dolphins! I did not expect them this early in the season, because of the relatively cold water. But I also noticed that when the two seas (Ionian Sea and Adriatic Sea) met, the water temperature rose from 15 to 17 degrees and the depth went from 40 to 90 meters. Apparently this spot was perfect for dolphins. Bonus, 3 fun facts about dolphins: * Dolphins are incredible athletes. They swim 50-100 kilometers every day, reach speeds of up to 40 km/h and are able to make impressive jumps out of the water, sometimes up to 6 meters high! * Did you know that dolphins can experience emotions such as happiness and sadness? They show empathy towards other members of their group and even have the ability to care for each other when sick or injured. They have an extensive social life, communicating with each other through complex clicking patterns and can even call each other by name * Dolphins have unique sleeping habits because they rest only part of their brains at a time so they can continue breathing and stay alert for predators. This phenomenon is called unihemispheric sleep. During this sleep they close one eye and keep the other open to detect possible dangers. They also switch eyes regularly so that both eyes can rest. Dolphins do not sleep continuously like humans do. They rest in short periods of a few minutes to half an hour during the day. In general, dolphins sleep about 8 hours a day

Water Palace Taman Ujung on the east coast of Bali is such tranquil and beautiful place to walk around. In my long format video here on this channel I have long drone shots from this and even from the foot of the mountain as well. Showing you the less visited places of Bali and even the best place for snorkeling not far from Kuta or Sanur Thank you so much for watching

March 14th...giornata della matematica, Pi Greco day. Perchè non utilizzare le cifre di π per costruire una spirale, la spirale di Archimede, da appendere in classe o nel corridoio? Se appesa sopra un termosifone o un'altra fonte di calore, diventa una divertente attività ed esperimento con cui scoprire alcune caratteristiche dell'aria: la spirale ruota e si muove perchè spostata dall'aria calda. L’aria calda è più leggera dell’aria fredda perché meno densa e sale verso l’alto. https://maestramonica.it/pi-greco-day-la-spirale-di-archimede-matematica/

We had a break in the weather, so we decided to head off to Long Island. Although we had originally planned to head to the Ragged Islands, it's perhaps too early in the winter season to do so. The periodicity of the weather events down here is every week or so and the wind coming next Monday would have been a challenge in the Ragged Islands. There's so few anchorages with protection from winds out of the West. Winds were light and variable. We were mostly on a broad reach or run all day. We used every sail. Once we made the turn to starboard back to the Bahamas Bank, we dropped the main, the gennaker and got out the Oxley Levante Parasail. Love that sail. It's so fun to fly. So, we'll stay here for a bit and head back to George Town, Bahamas and wait out the next blow. Hopefully we can make it over to Dean's Blue Hole, but we'll have to rent a car for the day.
