ABSTRACT:
A hollow mast having a longitudinal slot in the aft end thereof contains a stationary tension member supporting a rotatable rod having at least one C-shaped groove longitudinally disposed therein parallel to the tension member. The C-shaped groove is adapted to retain a bead located in the luff of a sail. A swivel surrounding the rod provides a rotatable part for hoisting the sail and a non-rotatable part for attachment of a sail hoisting halyard. A rotator is provided for rotating the rotatable member whereby the sail is furled about the rotatable member protected within the mast.
