Cosa tratta questo video

After two and a half years without a mast, Dan and Kika step Uma's new aluminum mast using a crane at the John Maas yard.▶ 0:00 The mast is built by John Maas, a Dutch manufacturer operating since 1971, and is configured for four headsails: a spinnaker halyard, a Code Zero halyard, a spare halyard, and a separate halyard for a larger Genoa, plus a solent stay with its own halyard — allowing two roller furlers on the bow for wing-on-wing downwind sailing without a spinnaker.▶ 3:01 The new boom features mid-boom mainsheet attachment, internally run reefing lines, an outhaul, and a hydraulic boom vang replacing a topping lift.▶ 8:09 Spreader lights are Lumetech dimmable red/white units on Deutsch plugs; turnbuckles are Blue Wave stainless-steel chassis with press-fit bronze threads to prevent galling.▶ 4:09 Two factory-installed conduits run inside the mast — a lesson from a difficult retrofit in Puerto Rico.▶ 6:53 John Maas seals the mast base with a foam block and poured epoxy to stop water tracking into the bilge, a problem Uma's old mast caused for years.▶ 24:09 Forestay, furler, backstay, and shrouds are set but final tuning waits until the boat is back in the water.▶ 18:07 Sail measurement is the next step.▶ 28:09
