This update rebuilds certificate calculation on the actual French merchant navy rules, validated with serving officers. STCW CERTIFICATES • Dual-purpose duty finally counted right: 50/50 deck-engine attribution, never counting a day twice • New certificates: dual-purpose chief officer (grants both Chief Mate AND Second Engineer), first-class Master, 8,000 kW Second and Chief Engineer • Each curriculum sees its real path: 3,000 GT Chief Mate for deck, 8,000 kW Second Engineer for engine • Regulatory reduction applied automatically for master certificate: 36 months reduced to 24 after 12 months as certificated second • New Dual-purpose tab in Career • Gas and cable officers: set the function declared by your shipowner - that is what counts SEA TIME CALCULATOR • Days computed by the official French rule, consistent everywhere • Roles grouped by category, months and days displayed side by side VOYAGES • Same-day voyages (ferry, shuttle) are now accepted • More flexible calendar: chain two voyages on the same day (short call) • Easier port entry • Fixed route drawing at very high latitudes • Port database cleaned: about forty mispositioned duplicates removed Certificate conditions remain indicative - check with your maritime authority before any official application.
