Steady two-dimensional flow past a sail is considered. The sail is assumed to be supported by two masts. The flow and the shape of the sail are determined as functions of the direction alpha of the flow at infinity and the Weber number lambda. The full nonlinear problem is formulated as an integro-differential equation for the shape of the sail. This equation is discretized and solved numerically by Newtons method. Sail profiles, the slack in the sail, and the lift coefficient are presented for various values of alpha and lambda.
