DynaRig Concept

Based on proof-of-concept : The Maltese Falcon

        The Dynarig was developed in Germany during the 1960s by the engineer Wilhelm Prolss. The rig was built for the purpose of commercial ships... But, unfortunately due to lack of materiel during those days no DynaShips were built, so it headed to the archives. Then came along Tom Perkins. He allowed to revive the concept and provided a beautiful proof of concept, The Maltese Falcon (noted : MF). The ship itself is truly a work of art and I will say props to Dykstra, the naval architects, as well as the engineers behind the yacht. 
  I could discuss about the overall ship more, but I will solely focus on the sail and performance aspect the Dynarig presents. Let's begin. 

        Firstly, let's discuss the mast and sails. The mast is composed of carbon fiber which is a material that changed the game because of the benefits it provided, and it also gave access to its conception.
  The mast doesn't have much compression load to its base, but it does need considerable bending and torque support. Thus, making the key Innovation aspects : the rotation of the mast which engages for better wind angles and the auto winching associated to sail handling which is done electrically. Essentially, a single person could sail it. 

  Then we have the sails. They are seperated in four divisions : Courses (bottom), Topsails, Gallants and finally the Royals (at very top). The seperation in divisions allows for the usage of all sails or a specific few... it is at the crews advantage to make the choice to allow for maximum wind usage. 
  For the MF (picture below), we can see the composition of 15 sails, that allows a decrease in impact of loadings and gives more performance. The sail manufacturer here was Doyle Sailmakers, and they've used standard Dacron sails. I've heard there's a new type of sail now called 3Di much more reliable and performant, but costly. I'll probably get into that later on.

        Secondly, let's examine the performance aspect. Again for a ship to be truly performant there must be the right choice of hull, propulsion etc. It is really important to have harmony in a ship. Here, MF has a narrow hull which enforces her "fast looks" , and as for the performance of the rig it is noted that its peak performance is upwind, so in the direction from which the wind is blowing. It also provides a stable and cruise like performance.
 Tom Perkins once noted that the ship hit 20 kts and kept that same performance. Which is very good knowing it is a 1,240 ton ship. We can also take MF's big sister, the Black Pearl. She can cross the atlantique with simply 20liters of fuel! 
 

Beautiful fuel reduction and eco friendly yatching!
