Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Dufour Yachts 430 GRAND LARGE is a 13.2-meter fractional sloop designed by Umberto Felci and built by Dufour Yachts since 2019. It features a fin with bulb and spade rudder hull, a 4.3-meter beam, a 2.1-meter draft, and displaces 9700 kg. Aboard *SmoCo Sailing*'s Dufour Yachts 430 GRAND LARGE, *Cosmo*, Armand and Liya prepared for full-time cruising by addressing recurring maintenance issues like a leaking forward V-berth water tank, a corroded radar mount, and a faulty shower drain.12:59 They replaced faulty water tank selector valves with 15mm Whale push-fit valves after 1/2-inch SharkBite fittings proved incompatible with the boat's 15mm tubing.3:00 During a 29-hour passage from Monterey to Avila Beach, the crew hand-steered through 20- to 25-knot winds and beam seas, confirming the effectiveness of their interior stowage and gear lashing.20:28 They planned to install a custom solar arch and dinghy davit system from Atlantic Towers to improve dinghy handling and increase solar capacity.3:38 While anchored in Santa Barbara, the crew installed a custom steel brace to stabilize the outboard motor lift and adjusted their Victron MultiPlus 2 inverter settings to accommodate a portable generator for power demands.21:30 In La Paz, Mexico, the crew discovered milky, salt-contaminated oil in their sail drive, necessitating multiple oil extractions and a haul-out for repair.3:41 A review in *SEILmagasinet* evaluated the Dufour 430 GRAND LARGE's performance in light winds and its cockpit ergonomics for cruising.26:56
