The first boat RNLB Prudential was powered by a single 80 bhp Weyburn petrol engine driving a single-screw while the two later boats were powered by twin Weyburn 40 bhp CE 4 4-cylinder units driving twin-screws.The first boat was built by S. E. Saunders at Cowes while the other two were constructed by J. Samuel White, also at Cowes.
