In this blogg, somewhere, I referred to the German Beetle car only making sense from an engineering perspective as a motorized rail trolley and that Poland, meaning Prussia, Warsaw and Bohemia, had build like no second railways since the first locomotive ran in Franconia, being historically tightly connected in also fighting the Germans aka Teutonic Order.
They also have a lot of lakes.... do you know that stone game?

With the inner hull bearing-mounted to the outer hull, you’re effectively building a **gyro-stabilized powered skipping stone**. The bearing idea solves one of the biggest problems: the outer hull can spin for gyroscopic stability while the inner hull stays habitable and non-rotating.
But the bearings don’t directly set the speed. The speed is limited by power, water-impact loads, hull shape, and sea state.

## Route distance
From **Gdańsk** to **Himmerfjärden**, across the Baltic:
- Direct straight-line distance: roughly **280 nautical miles / 520 km**
- A practical sea route around Bornholm, Gotland, and through the archipelago: roughly **350–450 nautical miles / 650–830 km**
If your saucer-boat can skip or fly in a straight line over open water, the direct route is possible. If it has to navigate like a normal vessel, the distance grows.

## Potential speed and travel time
Assuming the craft works as a high-speed skipping/ground-effect vehicle:
| Speed | Direct route: 280 nm | Practical route: 350–450 nm |
|---|---:|---:|
| 80 knots | 3.5 hours | 4.4–5.6 hours |
| 120 knots | 2.3 hours | 2.9–3.8 hours |
| 160 knots | 1.75 hours | 2.2–2.8 hours |
| 200 knots | 1.4 hours | 1.75–2.25 hours |
| 250 knots | 1.1 hours | 1.4–1.8 hours |
| 300 knots | 0.9 hours | 1.2–1.5 hours |
In practice:
- **80–120 knots**: plausible for a very aggressive hydroplane/skipping craft.
- **150–250 knots**: only realistic if it is mostly flying in ground effect, not repeatedly slamming into the water.
- **300 knots**: extreme ekranoplan-like performance. A saucer shape is aerodynamically poor, so this is unlikely.

## The bearing/gyro effect
A skipping stone needs spin to stay stable. Your bearing-mounted outer hull allows the outer hull to act as a giant gyroscope while the inner hull stays level.
But there are trade-offs:
- If the outer hull spins too fast and then hits water, the rim speed adds to the impact speed, causing huge spray and drag.
- Water impacts will put enormous shock loads through the bearings.
- The gyroscopic torque from skipping may try to precess the hull, so you still need active control surfaces or thrust vectoring.
So the bearings help with stability, but they do not remove the speed limit.
---
## What really limits the speed
A rough engineering estimate:
For a 10-tonne craft with about 4,000 kW / 5,400 hp:
- In hard skipping mode, where water impacts are included, effective lift-to-drag ratio might be only about 1.5.
This gives a sustainable speed of roughly **120 knots**.
- In clean ground-effect flight, with lift-to-drag ratio around 5, the same power could theoretically push it much faster, but wave clearance, control, and structural loads would cap it in the **200–250 knot** range.
The Baltic is often choppy, with short steep waves. That makes sustained stone-skipping behavior extremely difficult above about 100–150 knots.
---
## Bottom line
If your bearing-stabilized saucer-boat actually worked:
- A realistic first-generation version might cross from **Gdańsk to Himmerfjärden in about 2–3 hours**.
- A highly advanced ground-effect version could potentially do it in **about 1–1.5 hours**.
But the saucer shape, water impacts, and Baltic sea state would make anything faster than that very difficult. The bearings are a clever piece of the puzzle, but the real limits are power, hydrodynamics, and structural survival.
