Anyone who is concerned with excessive fuel consumption, the increase in potential engine-fatigue, the increase in running-gear maintenance and their associated cost. No vessel is immune. Be it a tug-boat, naval ship, sailing yacht, motor yacht, fishing boat, or cruise ship! Today's boat-owner would never consider launching his vessel in heavily fouled waters without protecting the bottom. The protection of the running gear is just as important for a vessels long-term performance.
