What this video covers

The Cantieri d'Este Class 40, designed by Sito Aviles Ramos, features a retractable keel that reduces draft from 3 metres to 1.60 metres, allowing the boat to enter standard marina berths — a cruising-oriented feature unusual in the class.Watch Hull construction uses epoxy resin sandwich with unidirectional and biaxial fabrics over a Corecell core; carbon is restricted by class rules to mast, boom, and bowsprit only.1:23 The mast stands 19 metres above the waterline with two spreader sets; the mainsail measures 73 square metres and the genoa 42.2:45 Twin rudders are mounted wide outboard so the windward blade lifts clear at low heel angles, reducing drag and lightening helm feel.1:44 Water ballast transfers 750 litres side to side in one minute.6:26 On the water at 32–34 degrees apparent, the boat tacks quickly and recovers speed within seconds; in 8–9 knots of true wind it reaches 7–7.5 knots of boat speed.2:10 Displacement sits at the class limit of 4,500 kg, with 1,600 kg in the keel.6:05 Below, three cabins, a head, and a nav station are arranged with the saloon forward, giving privacy uncommon in a race-oriented 40-footer.6:22
