2. Banshee (dinghy) - Wikipedia

   en.wikipedia.org/wiki/Banshee_(dinghy)

   The Banshee is a recreational sailboat, built predominantly of fiberglass, with foam flotation, making the boat unsinkable. It has an unstayed catboat rig, with aluminum spars, including a non-rotating mast, a loose-footed, four-batten mainsail, a spooned raked stem, a vertical transom, a transom-hung, kick-up rudder controlled by a tiller and ...

   en.wikipedia.org/wiki/LightSail

   LightSail is a follow-on project to Cosmos 1 — a solar-sail spacecraft designed by The Planetary Society in the early 2000s, which was destroyed during a launch failure in 2005. Both LightSail spacecraft measured 30 cm × 10 cm × 10 cm (11.8 in × 3.9 in × 3.9 in) (3U CubeSat) in their stowed configuration. After sail deployment, the total ...

4. Forces on sails - Wikipedia

   en.wikipedia.org/wiki/Forces_on_sails

   Forces on sails. Aerodynamic force components for two points of sail. Left-hand boat: Down wind with stalled airfow— predominant drag component propels the boat with little heeling moment. Right-hand boat: Up wind (close-hauled) with attached airflow—predominant lift component both propels the boat and contributes to heel.

5. High-performance sailing - Wikipedia

   en.wikipedia.org/wiki/High-performance_sailing

   High-performance sailing. High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail ...

   Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named Starchip, [1] to be capable of making the journey to the Alpha Centauri star system 4.34 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark ...

7. Sailmaker - Wikipedia

   en.wikipedia.org/wiki/Sailmaker

   Sailmaker. A sailmaker makes and repairs sails for sailboats, kites, hang gliders, wind art, architectural sails, or other structures using sails. A sailmaker typically works on shore in a sail loft; the sail loft has other sailmakers. Large ocean-going sailing ships often had sailmakers in the crew. The sailmaker maintained and repaired sails.
