Draw a freebody diagram, it will explain it really well

the boat is floating on top of the water, which means that the net acceleration in the y direction must be zero

the boat is not sinking (dominant downwards acceleration/force)
the boat is not flying (dominant upward acceleration/force)

that measn

F_(net_y) =0

now, if you drew the FBD, you only have 2 forces acting on the boat.
the upward bouyancy force on the boat and the downward force due to weight


F_(net_y)= F_(bouyancy) - F_(weight)

since the net force is equal to zero


F_(bouyancy) - F_(weight) = 0

and thus


F_(bouyancy) = F_(weight)
