The pilothouse allows turning the ship's wheel to activate the rudder, complemented by functional boarding stages that raise and rotate, plus a deployable anchor. Inside, the Texas deck reveals a crew cabin and bathroom, while the main deck hosts a music stage and a restaurant. The boiler deck completes the experience with a kitchen and a steam engine museum showcasing a LEGO working piston and a Watt steam engine.
