I'm getting into board building and am interested in using an engineering based approach. Does anyone have any links or content related to simulation and real data? Fluid dynamics, test data etc? Thanks.
None I am aware of but Tim Gourlay (current lightweight world champ in the Windsurfer LT class and super fast on any windsurfer craft) & Jon Martelotta have done some aero-hydrodynamic analysis of the RS-X:

Summary: "The RS:X Olympic sailboard is an all-round board designed to be raced in 4 to 25 knots of wind, and is an example of the current state-of-the-art in sailboard design. This board has been chosen as the specific example for an overview of sailboard aero-hydrodynamics. The current article brings together previous research on sailboard sail and fin lift, and applies it to the case of the RS:X sailboard. Measured sail camber and twist, as well as mast stiffness and deflection, are described for realistic upwind racing settings. The three-dimensional force and moment balance of an RS:X sailing upwind is investigated, in order to determine the limits on righting moment, sail lift and fin lift for different wind strengths. Finally a planing analysis is performed on the RS:X sailboard to calculate trim, wetted length and resistance."
The article contains reference to some research which might help.
