Sailor points to preventer line holding boom over water
Hva denne videoen dekker
A mainsail batten pops out of its Sea-Tek batten box roughly 85 feet up the rig during rough overnight conditions, leaving Chris unable to drop the mainsail safely on a solo offshore passage.3:03 Rather than going aloft, he rigs a preventer to hold the boom out near 90 degrees, then drops the mainsail so the 10–11-foot fiberglass batten can work its way past the spreaders and down to the deck.7:16 The technique works; the batten is recovered without mast climbing.26:21 Along the way, Chris explains his preventer setup in detail: an orange line running from the boom end through a turning block on the foredeck and back to the cockpit, with a stretchable nylon section near the boom and a stiffer tail toward the cockpit.9:47 He argues against an all-Dyneema preventer on a high-load performance boat, saying the leverage would rip deck fittings out regardless of backing plates.13:51 He also covers the flat-top mainsail's interaction with running backstays as the likely cause of repeated batten failures, and explains why he chose fiberglass over carbon battens while troubleshooting the design.8:31 The boat runs a 130 hp Volvo Penta TAMD 31 and carries 400 liters of fuel.0:23 Key takeaways: clip on, know how to heave-to, and always run the preventer to the bow when the boom is beyond the traveler.27:43
