What this video covers
Reefing a mainsail with a Selden in-mast furling system requires specific preparation to ensure a clean, jam-free roll. Before furling, set the mast mechanism to ratchet mode to prevent the sail from unrolling.0:46 Tack the boat onto a starboard tack to provide the cleanest entry angle into the mast.1:08 Release the backstay tension to straighten the mast, which reduces friction during the furling process.1:31 While maintaining a close-hauled course of approximately 30 degrees apparent, ease the mainsail to luffing while simultaneously managing the outhaul tension.3:24 A team approach is necessary to coordinate the furling line and outhaul to prevent crinkles in the sail.4:40 Once the desired reef is set, re-tension the outhaul to flatten the foot of the sail and re-apply backstay tension to tighten the forestay and depower the rig.4:50 If conditions are too challenging, bear away downwind, furl the jib, and use the engine to stabilize the boat during the reefing maneuver.2:40
