Southern Spars, a UK-based company with experience in sail-powered superyachts, has joined the International Windship Association (IWSA), a not-for-profit organisation that promotes and helps to facilitate the uptake of wind propulsion solutions in the commercial fleet.

Southern Spars, a division of North Technology Group, specialises in design and manufcature of DynaRig systems. The DynaRig concept was first envisioned by Wilhelm Prolls in the 1960s, and has reportedly proven itself as an effective alternative to conventional rigs in the superyacht segment, allowing reduced crew numbers and optimised sailing time. With a view to the next generation of the system, aimed as primary and auxillary propulsion for commercial ships, Southern Spars has partnered with Magma Structures.

Andy Shaw, DynaRig Specialist, said: “With requirements to cut emissions and increasing fuel prices, there is an ever-growing demand for wind-assisted solutions for commercial shipping. Southern Spars has joined the IWSA as a world leader in the design and manufacture of sailing rig solutions. We are working on several commercial shipping and workboat projects for various wind-assisted solutions and for DynaRig systems similar to the rigs installed on the superyachts Maltese Falcon and Black Pearl.

The DynaRig system on these two large yachts has provided a significant amount of performance data, which validates that the sytem as being effective for fairly large vessels. The Maltese Falcon is a 88m long self-standing three-mast square rigger with a sail area of 2,396 m2 and lthe Black Pearl is 107m with 2,900 m2 of sail, with a maximum speed of 30 knots under sail alone.

“It is a great pleasure to welcome such a specialist design team to the International Windship Association family and we are all eager to learn more about the commercial shipping projects that are currently in the pipeline. This is a critical time in the development of commercial wind propulsion and we look forward to working with the Southern Spars team to help deliver a wind propulsion future for the world fleet.” said Gavin Allwright, IWSA Secretary General.
