PBCF model tests confirm fuel efficiency

摘要

THE PBCF (propeller boss cap fin) is a well-established device which can cut fuel consumption and exhaust gases by up to 5%, incurs no additional maintenance costs once installed, and is manufactured by Mitsui OSK Techno Trade, of Japan. We have discussed this propeller-enhancing device comprehensively on several occasions in The Naval Architect, most recently in July/August 2004, page 32, and in October 2003, page 33, and now, further evaluation of the PBCF's performance has taken place, through large-scale model tests this March.
