The clean, crisp look of aluminum is perfect for performance-oriented yachts. Sideplates are constructed of Hardkote-anodized 6061-T6 aluminum for strength and corrosion resistance. The ultralight composite bearing system (ULC) rides on a heat-treated stainless steel inner race to handle extremely high loads. Snap-fit Torlon® ball bearings carry thrust loads.
