θ = {sin}^{- 1} (\frac{| V_{W L} |}{| V_{B W} |})

$theta = sin^-1( | V_(WL) |/| V_(BW) |)$

$(V_(WL))"Velocity of the water current."$

$(V_(BW))"Forward velocity of the boat."$

The Flow Compensation Angle equation computes the angle (Θ) needed to steer /attachments/0089582b-2808-11e6-9770-bc764e2038f2/Boat and River.png Boat traversing river up-stream enough to achieve a straight course across a flow based on the speed of the vehicle (V_BW) and the speed of the current (V_LW). This is an exercise in vectors. See Diagram.

INSTRUCTIONS: Choose your preferred velocity units and enterr the following:

(V_BW) - Velocity of the boat
(V_LW) - Velocity of the current of the river.

The calculator returns the needed angle (Θ) upstream to keep a direct coarse across the river. Note, if the velocity of the boat is less than the velocity of the current, it is impossible to go straight across.
