Laws of Motion-magnitude/accel-Gerry has mass issues!

1. The problem statement, all variables and given/known data
The wind exerts a force of 420 N toward the south on the sails of Gerry’s sailboat, while the water exerts a force on the sailboat of 160 N west.The boat and Gerry have a combined mass of 320 kg, what are the magnitude and direction of the sailboat’s acceleration?

2. Relevant equations
f= sqrt(Force 1^2+Force 2^2)

3. The attempt at a solution
I need to find the total force of the boat.

F=sqrt((420)^2+(160)^2))

F=sqrt(202000)

F=449.44 N

I would appreciate some guidance.
