This can be achieved using Datum Electronics’ Shaft Power Management Kit (SPMK) – a temporary declared engine power measurement system which installs directly onto the fishing vessel’s propulsion shaft – with the test data logged and stored for use as evidence.  The SPMK system is designed to be easily installed by the end user in under 30 minutes, then quickly removed again after running an engine test to full power and logging the results in kW.  The Datum SPMK system generates test results accepted by the MCA, MSEVT and many other EU fishery agencies for the purposes of fishing vessel licencing.
