• The app is now called Navigation Zero, with a new mark, a new icon and a new launch screen. • New welcome screens on first launch: what the app does and where to start. • Hybrid conversion “From requirements”: state speed, hours and range, and get the engine, hybrid module, gearbox and battery bank — with every assumption declared. • Updated manual.

• Fix: every plan now shows exactly the price your store charges, in your own currency. On Android, the Integrators tier showed an amount that differed from the one at checkout.

• New: the “High-speed craft classification” card shows whether the boat stops being a high-speed craft after the conversion — and then no operator licence is needed. • New: the app icon shows unread notifications; tapping a new-version one takes you straight to the store, and pulling down refreshes the list. • New: newsletter subscription from the Account screen. • Fix: an offer or certificate you deleted could come back on the next sync.

• New: the update notice now comes straight from the store — you hear about a new version as soon as it is out. • Fix: “Restore purchases” always answers — tier restored, no purchase found for this account, or store not responding. • New: the DEAS certificate registry records the engine identity — both engines when they differ.

• New: the DEAS certificate now records a second engine when the two differ from each other (standard v2.0). • New: on inflatables you can state the rigid hull beam, without the tubes. The tubes do not lift the boat, and the overall beam overstated power by up to a quarter. • New: the quotation shows the make and model of the existing engine — both lines when the engines differ. • New: optional anonymous contribution to standard calibration, with a switch in Settings. Nothing identifying you or the boat is sent. • Fix: the certificate and the conversion calculation gave different power for the same inflatable. They now agree.

• New: state the diameter of the propeller already on the boat and the calculation stops proposing a reduction that needs a propeller which does not fit. • New: in Regeneration under sail you now see the speed the motor must turn and its percentage of rated — too low and the controller may not charge at all, above rated it limits. • Improvement: the electrical figure for regeneration now states explicitly that it assumes 85% conversion efficiency. • Plan change: all of regeneration — calculator and measurement database — now belongs to Professional, where sailboats belong too. • Fix: a PDF signature file is now recognised by its content. On Android the name often arrives without an extension and the upload failed silently. • Fix: on shallow boats the shaft immersion no longer exceeds the hull draft — the cavitation check is now correct where it matters most.

• New: in Regeneration under sail you now see how many knots charging costs you — enter waterline length, beam and displacement. The calculation respects your propeller type: a folding one loses less than a fixed one. • Improved: the app opens straight away, with no prompts at startup. Notifications are now requested when you open their own screen. • Improved: you are told when your version can no longer produce a correct result, because prices, the catalogue or the DEAS methodology have changed. • Important: the registry number and QR code mean certification, so they are now issued only with a live measurement by a certified DEAS inspector. The calculation, the grade and the PDF remain free for everyone. • Fix: the trip's monetary benefit did not match the totals shown on the same screen. Fuel for the service loads was charged to the electric side but not to the thermal one; the two columns are now compared as complete totals. • Fix: the service-load batteries now also offer a PowerTech alternative in 2, 3 and 4 packs — noticeably cheaper than the Transfluid equivalent. • Fix: solar is no longer pre-filled with a fixed 4 kWp; whatever you entered in the form is carried over. • Fix: setup suggestions no longer propose a bigger generator — calculations use what you declared. • Plan change: Regeneration under sail — both the calculator and the measurement database — now belongs entirely to the Professional plan, where sailboats belong too. The database was mistakenly in a lower plan than the calculator it documents.

• New: state your propeller type in Regeneration under sail — fixed, folding or feathering. It changes the calculation and what the figure guarantees. • New: steerable nozzle in Bollard pull, independent of vessel type. • New: “Charging” in the menu — charging points and booking, coming soon. • Fix: the manual applied to a folding propeller the drag that belongs to the folded one. • Motor catalogue updated.

• New: regeneration under sail — with the sails up the propeller charges the batteries; add your own readings and compare them with theory • New: the price is shown too — charging adds drag, so it costs a little speed • New: bollard pull for tugs and pushboats • New: live diesel and petrol prices by country — and by prefecture in Greece • Fix: more accurate savings in the quotation and generator fuel priced correctly #################################################################

• New: conformity classes on DEAS certificates — S (self-declared), D (documented), V (verified) • New: verified certificates (class V) issued by certified DEAS inspectors via a live on-water measurement • Improvement: the DEAS wizard now accepts comma decimals and keeps your entries when scrolling • Improvement: the live-measurement option is always shown, with a hint when details are missing

• New: Live measurement underway via NMEA 2000 — automatic consumption (Method M1) with nautical gauges and a connection check • New: every measurement is stored as tamper-evident evidence; enough of them unlock Level 3 (operational data) • New: equipment guide with wiring diagrams; new colored DEAS emblem

• New: DEAS gets its own logo and launch screen, plus an Initial/Final certificate distinction • New: Hybrid Conversion now produces a full offer (preview, print, share) with a DEAS page • Improved: GPS-suggested location, more accurate shaft diameter, and fixing fields after a DEAS result
