Abstract

A mast fairing for a sailboat includes an upper fairing and an optional lower fairing configured to reduce turbulent airflow over the upwind and downwind sides of a sail. The upper fairing includes a fairing wrap includes a central segment configured to wrap around a mast, a left-side panel, a right-side panel, and a sail track attached to trailing edges of the left- and right-side panels. One or more fairing supports are optionally attached to the sail track between the left- and right-side panels of the fairing wrap. The optional lower fairing includes a central segment, a left-side panel, and a right-side panel configured for installation on a mast and boom below the upper fairing. The upper and lower fairings reduce turbulent airflow over the surfaces of a sail and increase regions of laminar airflow to improve the performance of the sail.
