What's new

Version 1.10.1 · 16 Oct 2026 · 5 days ago

Three calculators that now answer correctly • Fixed: the Dutchman's Log showed twice the speed. You time an object thrown in at the bow until it passes the stern – but the calculation assumed twice the vessel's length. 10 metres in 5 seconds came out as 7.8 knots instead of 3.9. • Fixed: the ETA Calculator accepted a speed of 0. It then returned the departure time as the arrival and a duration of zero hours – "already there" with the vessel stopped. The entry is now rejected with a message. • Fixed: in the Current Triangle a speed of 0 did nothing at all under "Steering Course" and "Determine Current" – no result and no hint as to what was wrong. Under "Course over Ground" the hint did appear, but in German whatever the app language.
