She was completed with just the pole main mast that was placed just ahead of the rear conning tower, but around the time she entered service in 1909, a pole fore mast was installed atop her forward conning tower as well. By 1917, the fore mast had been replaced with a sturdier tripod mast to support a spotting top to help the direction of her armament. Steering was controlled by a single rudder. Her crew numbered 26 officers and 910 enlisted men.
