Paper awarded by RINA
The paper “Comparison of modern keel types for sail boats” was published in late 2017. The study systematically evaluated the hydrodynamic performance of different types of bulb keels. Recently, the paper was awarded with two prizes at the Royal Institution of Naval Architects (RINA) annual meeting. The Institution’s Medal of Distinction and the Austin Farrar Prize.
The authors Kasper Ljungqvist, Michal Orych, Prof. Lars Larsson and PhD Christian Finnsgård were awarded the Institution’s Medal of Distinction and Kasper Ljungqvist was also awarded the Austin Farrar Prize for the same paper, which was considered the best published small craft paper of the year 2017-18 by an author under the age of 35.
- “SSPA and the authors are very glad that papers including yacht design are recognised”, said Kasper Ljungqvist, Naval Architect at SSPA, when he represented the authors at the ceremony.

Modern keel types for sailing yachts
Have you ever reflected over the different types of bulbs chosen for yacht keels? Today there is no general agreement on which bulb type is preferred for different types of yachts and very little scientific investigation has been done in this area. SSPA and Chalmers have carried out a study, where the hydrodynamic performance of different types of bulb keels were systematically evaluated. A paper is published in the International Journal of Small Craft Technology (IJSCT), a RINA Publication.
Sailing, aerodynamics in waves
Prediction and analysis of added hydrodynamic resistance in waves is an established research topic, with several accepted methods, but the study of sail aerodynamics in waves is an open research area. SSPA and Chalmers are cooperating in the Sports & Technology initiative, with several research projects in sailing. The leading journal Ocean Engineering has recently published a paper titled “CFD prediction of steady and unsteady upwind sail aerodynamics”.
