What this video covers
Rigging a boom preventer and a whisker pole allows for safe downwind sailing in "wing-on-wing" configuration, preventing accidental jibes in heavy seas.0:59 To install the preventer, run a Dyneema line from the end of the boom forward to a bow block or cleat, then lead it back to a cockpit winch.5:39 Attaching the preventer to the end of the boom is critical; mid-boom attachment points risk snapping the spar under load if it dips into the water.5:30 When sailing downwind, the preventer keeps the boom locked, while the whisker pole holds the genoa out on the opposite side.1:21 The pole requires three control lines: an uphaul, a downhaul, and a foreguy.13:56 If an accidental jibe occurs while the preventer is set, the crew must ease the preventer line while simultaneously tensioning the mainsheet to complete the maneuver in a controlled manner.10:40 This classic setup relies on standard lines and hardware available on most cruising vessels.16:43
