Roller Reefing a Jib:
Sailing deep (off the
wind - deep broad reach or running reach), with the headsail in the lee of the main, you can easily furl even a 140%
genoa without using a winch. The mainsail will tend to shield the jib from the
wind. Mild tensioning is kept on the jib's sheet to enable the jib to wrap snugly around the headstay/foil. This will prevent excess luffing of the sail and make furling easier. In a pinch, you can always let the jib out, by loosening it's sheet and rolling in the
furler, but in high winds excess luffing may occur and this can damage the sail. The
roller furling line must be carefully handled in a high-wind situation, or the wind may overpower the sailor and unfurl the sail. As you loosen this line, a high-wind may pull the line through your hands and unintentionally unroll the jib. It is sometimes helpful to place several loops of the line around a winch so the line can be
stabilized. Then loosen the jib's sheet and with your hands pull in the jib's furling line.
The same problem exists when unfurling the jib in a high-wind situation. First loosen the furling line by a few feet and then secure it. Then un-furl the jib using the jib's working sheet. If you unroll the jib first with the sheet and the wind catches the sail, it may fully unroll the jib and pull the furling line through your hands. Thus, secure the furling line first.
NEVER TIGHTEN THE JIB's FURLING LINE USING A WINCH HANDLE. If the line gets caught on the forestay, this could bring down your
rigging and in a high-wind situation dismast the
boat.
There should be enough
roller furling line to fully furl the jib, wrapping the sheet around it several times, regardless of the tightness of the furl.
