The video explores the intricacies of engine performance in shipbuilding within a game, focusing on the debate surrounding the S 6830 engines and their effectiveness. The creator delves into statistical analyses and testing to debunk the belief that these engines are the best, highlighting their drawbacks, such as low top speed and poor thrust-to-mass ratio. The discussion encompasses various aspects of ship mechanics, including mass impact on top speed and boost speed, the relationship between engine class (A, B, C) and performance, and the significant role of thrust-to-mass ratio in determining acceleration and maneuverability.
Key points include the comparison of lightweight combat ships to heavy cargo ships, revealing the influence of mass on boost speeds. The video also explains that while Class A engines offer the best thrust-to-mass ratio, Class C engines provide the highest total thrust but suffer in boost performance. The importance of engine choice, not just for achieving top speeds but also for efficient maneuverability and acceleration, is emphasized throughout.
Specific engines like the White Dwarf series and Slat engines (Class A sa 433s and Class B SAE 560s) are highlighted for their superior performance metrics. The video further clarifies the misconception surrounding the Mobility stat, stating that practical mobility depends more on thrust and acceleration rather than the stat itself.
The speaker's personal preferences are shared metaphorically, preferring sports car-like engines for agility over bus-like engines for heavy cargo, depending on the ship's purpose. The overall conclusion encourages viewers to consider these detailed insights to make well-informed decisions in their shipbuilding endeavors.

In this part of the video, the creator addresses a common debate among ship builders about the effectiveness of the S 6830 engines in a game. They challenge the belief that the S 6830s are the best engines by delving into detailed statistics and planned tests. The creator shares their past preference for these engines and highlights factors driving their popularity, including their quest-locked status and high maneuvering thrust. However, the engines suffer from the slowest top speed and high mass, diminishing their advantages. The segment then explains that engines provide mobility and top speed, requiring an analysis of several stats to determine the best engine overall. It further outlines the speed limitations by engine class (A, B, and C) and mentions that a ship’s top speed is determined by its slowest engine.

In this segment of the video, the speaker discusses how a ship’s mass impacts its top speed and boost speed in a game. They conduct a side-by-side comparison between a lightweight combat ship and a heavy cargo ship. Both ships, regardless of mass, achieve a max top speed of 280 due to the game’s mechanics and various boosts from skills and crew members. However, when engaging the engine boost, the lightweight ship reaches a higher boost speed than the heavy cargo ship. The speaker explains that mass doesn’t affect the baseline top speed but significantly impacts boost speed.
They also delve into the calculations of engine thrust during boosts, revealing inconsistencies where boosted engine thrust isn’t a simple multiplier of the base engine thrust. Testing different ship masses showed that boost speeds for very heavy ships plateau at around double the top speed while very lightweight ships see no significant change. The boost effectively raises the maximum top speed, but this boosted top speed is capped based on ship class: four times for Class A, 3.75 times for Class B, and 3.5 times for Class C.
00:10:00
In this segment of the video, the speaker explains the mechanics and trade-offs associated with different classes of ship engines, particularly focusing on Boost speed and how it is affected by the ship’s Mass and engine performance. Class C engines are the slowest and offer lower Boost speed compared to Class A, which are the fastest. Adding more mass to the ship affects Boost speed negatively, unless the engine’s thrust-to-mass ratio is optimized, ideally around 40 to 45. The speaker highlights that the S 6830 engine has a poor thrust-to-mass ratio, making it one of the worst for boosting. Additionally, the Amon 7 engines have a higher Boost speed than the white dwarf 315s, but only for a brief moment. The video also touches on maneuvering thrust, noting that while top speed decreases from Class A to C, maneuvering thrust—and thus the ship’s mobility—increases with higher engine classes.

In this segment, the video discusses how the mass of a ship influences its mobility, which is a stat capped between 0 and 100 in the Ship Builder. It explains that even adding extra maneuvering thrust won’t push mobility beyond these limits. To test this, a ship with minimal mass and just above zero mobility is compared to a heavier ship with similar engines. The results show both ships rotate at the same rate, confirming a true minimum mobility value. Conversely, ships with maximum mobility also rotate at the same rate, regardless of extra maneuvering thrust, indicating a capped maximum. The presenter provides a calculation: total maneuvering thrust divided by 12.4 to determine the mass limit for maintaining maximum mobility. However, it’s clarified that the mobility stat primarily affects rotation speed rather than the ability to change travel direction.
00:20:00
In this segment of the video, the focus is on how engine thrust impacts a ship’s ability to change velocity, momentum, and acceleration. The presenter explains the challenge of isolating engine thrust by keeping other factors constant, such as top speed, maneuvering thrust, and mass. Two sets of engines from the same class but with different thrust values are compared: the White Dwarf 2030 and the Aries DT10. Tests show that for lightweight ships, the difference in acceleration to top speed is negligible, but for heavier ships, the difference is significant—about 7 seconds. The importance of the engine thrust per mass ratio, especially for heavy ships, is highlighted. Finally, the segment provides key conclusions regarding engine types, emphasizing that Class A engines generally offer the best thrust-to-mass ratio, while Class C engines provide the highest total thrust. The presenter emphasizes that while no single engine type is the “best,” understanding the impact of mass and engine thrust on acceleration and mobility is crucial.
00:25:00
In this segment of the video, the speaker discusses the importance of acceleration, not just in achieving top speed quickly, but also in changing directions efficiently. They highlight that mass significantly impacts engine performance and emphasize the superiority of certain engines, particularly the White Dwarf series and specific Slat engines (Class A sa 433s and Class B SAE 560s). Detailed calculations are provided to showcase how these engines outclass others in thrust-to-mass ratios, both in acceleration and maneuvering. The speaker also touches on the misconception of the Mobility stat and explains that real practical mobility depends on thrust and acceleration rather than just the Mobility rating. Finally, they point out that while the S 6830 engines are suitable for heavy cargo with decent Mobility stats, they fall short in actual performance metrics like boost thrust and speed.

In this part of the video, the speaker discusses their preference for driving a sports car over a city bus, using it as an analogy for engine choices in large, heavy cargo ships. They emphasize that the choice of engine and how it fits into an overall ship build is crucial and varies based on individual priorities, such as cargo capacity. The speaker hopes that their in-depth analysis has provided valuable information to help viewers make the best decisions for their ship builds. They conclude with a motivational note to keep building.
