Bow Thruster for 68' Roamer

I started a new thread since it is a different topic for the 68' Roamer. The previous owner stated that only one time in 18 years of owning the roamer did he really need a bow thruster. I have driven catamarans and smaller yachts to 50', fly airplanes and helicopters but the 68' will be a new length and challenge to me. Anyone have any advice? Try it then see? Or while I am doing a mini refit should I bite the bullet and put one in?
