Without Doyle's StackPack mainsail furling system, lowering the main often goes like this: the sail is flogging itself into early retirement, you've got a half-dozen sail ties clamped between your teeth, the channel makes a jog to port but the helmsperson doesn't, and your five-year-old finally gets to find out if the boathook floats.
NO NEED FOR SAIL TIES...
StackPack is a fully battened mainsail with integral lazy jacks and a cover that opens automatically to accept the sail as it is lowered. The cover and lazy jack system neatly flakes and holds the sail as it is lowered or reefed. The folds at the foot of a reefed mainsail also lie neatly in the StackPack cover, eliminating the need to tie off the excess fabric with ties.
EXTEND THE LIFE OF YOUR MAIN...
With the sail completely stowed, the StackPack system presents a neat appearance and automatically protects the sail from harmful UV rays. While sailing, the integral cover lies flat against the foot of the sail for a clean aerodynamic effect.
MAINTAIN SPEED AND SHAPE...
Cruising sailors are often faced with the dilemma of whether to sacrifice sail shape and quality for convenience. The StackPack is a solution for sailors wanting convenience without sacrificing speed and shape.
The StackPack also delivers a beautifully finished product that will look great on any boat. While designed principally as a mainsail furling system, StackPack works equally well with mizzens, staysails and other club-footed headsails.
