The ACCWing is essentially a twin-skinned sail that can be raised or lowered. It’s fully battened, can be reefed, and can change its section shape using its own internal muscles, operated by compressed air. It achieves this with ‘muscles’ fitted at various positions up the sail on the inside of the wing. The muscles consist of a braided line around flexible hoses, one on each side of the wing. When the hose contracts on one side, it pulls the sail into shape, creating a deeper camber. Having muscles in different positions up along the sail means the section shape can change with height, allowing the twist to be controlled and developing a smooth transition from top to bottom. The rotation of the masts changes the sail’s angle of attack. When it comes to sheet loads, wingsails are often light. This is thanks to the sail’s balancing effect ahead of the mast, much like the equilibrium on a spade rudder. It’s easy to imagine how this system could be totally automated to respond to wind speed and direction, both in section shape and with automated reefing. While you might turn your nose up at letting a computer and servos take over the boat, there will surely be shipping companies that’ll sit up and take note. Since the clipper ships went out of fashion, there’s never been a need for them to put muscles and sails in the same sentence.

Boat excursion Panarea & Stromboli By Night with boarding from Marina di Portorosa (ME) The day begins by sailing towards Panarea, the smallest of the Aeolian Islands but unique in its charm and beauty. It is characterized by diving and snorkeling sites, crystal clear waters, especially in Zimmari Beach and in the Calajunco Reserve, our first stops. On Panarea you will see incredible rock formations, coral reefs and a rugged and seductive silhouette sculpted by volcanic activity. At the end of the morning, we will disembark on the island for lunch; and this too will be an absolute experience, like the taste of the fish and our wines.

Relax, dive and swim are the prelude before mooring in Stromboli. A stroll before stopping at one of the meeting places frequented by the International Jet Set for an aperitif or, why not? A pizza waiting for the beginning of sunset to get back on board and head in front of the “Sciare del Fuoco”.

With eyes and soul full of amazement you will return quietly to port, ready to want to tell everyone what you have experienced.

Questa mattina ci svegliamo già qui. Il sole scalda la coperta e di conseguenza anche l’aria in barca. Ci svegliamo e facciamo subito tutti colazione, tranne @jackfink333 che resta a dormire ancora un po’. Oggi è una giornata di saluti. Abbiamo vissuto tre giorni PIENI. Pieni di progetti, di vita, di cibo, di risate, di cantate, di video. Pieni appunto. Lavoriamo con @easysea_official da più di un anno in remote working. Questo è stato il primo team building che abbiamo fatto insieme ed è stato pazzesco. Una volta partiti Antonella, Giuseppe, i due Franceschi e Gianluca si fa sera. Facciamo un tuffo e poi andiamo a mangiare una pizzetta proprio dove eravamo andati all’andata (qualcuno si ricorda il michiallegro?). Una serata piacevole. Con concerto di Paolo Belli finale. Domani, se tutto va secondo i piani ci divertiremo con Carmelo, vedrete anche voi se il meteo sarà dalla nostra. Buona notte e a domani Andrea
