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.

I've started the 2nd prototype wheelhouse extension (and dismantled the first). We had proved the concept but wanted the central fixed part a little narrower. The goals are a full cockpit enclosure AND moving the mainsheet from the top of the aft cabin to above the wheelhouse (better safety and a better sheeting angle). We also refitted the timber trim on the port side complete with the front zip for the first removable window section. We are now living aboard our Rival 38 Centre Cockpit full-time while finishing a refit so we can launch ASAP. We have a frequently updated blog at https://sustainablesailing.net with membership options and a weekly newsletter at £2 per month for Early Bird Supporters. Our free Sustainable Sailing book is at: https://sustainablesailing.codeberg.page/ Or visit our shop at https://sustainablesailing.teemill.com/ for great hoodies, t-shirts and bags. When we bought Vida in August 2019 she was in a very tired and damp condition with all original equipment and fittings (much of it not working). We have removed all the gas, diesel and paraffin equipment, and are installing all-electric (motor, cooking etc).
