Did you know that the clearance between the propeller shaft and the bearing should be measured during each in-water survey in lieu of drydocking? At #DivingStatus we use the vessel's unique poker gauge to measure the tailshaft weardown (top and bottom). In case the vessel does not have any, our company can manufacture all types of poker gauges suitable for any vessel. All measurements are taken according to IACS standards.
