Ship Maneuvering Simulatorv0.24

Released June 20, 2026Major

iOS

The latest major update for Ship Maneuvering Simulator shows a neutral impact, as the small sample size prevents a definitive performance assessment. While users noted improvements in general simulation stability, the release introduced a critical bug causing vessels to sink upon departure. The average rating shifted from 4.23 to 4.8, but this change lacks statistical significance due to the limited volume of feedback.

What changed

What worked

Performance
Users explicitly credited the latest update for addressing previous simulation stability issues.

What didn't

New feature
backfired
The introduction of new maneuvering models correlates with reports of vessels sinking immediately upon departure.

Marlvel takeaways

Investigate the port departure logic to resolve the vessel sinking bug reported post-update.
Monitor the timescale button interaction to ensure the recent fix remains stable across different device configurations.
Increase the sample size of user feedback before drawing conclusions on the new tug assistance and wind model features.

Original release notes

- All-new low-speed professional MMG handling model based on new research (Taniguchi & Maki, 2025) for even more realistic harbour manoeuvring, proper drift, propeller "walk", pivot point movement and rudder/propeller behaviour.
- Added tug assistance: control the tugs in lateral (push/pull) or longitudinal (bow/stern tug) mode to help you berth and unberth (available only on the Cargo Ship for now).
- Improved wind model
- Various handling and stability refinements.
- Fixed timescale button
