Entering Skim-Space: Upon activating their Wave Skim-Drive, a ship "flips" into Skim-Space. It feels to those aboard like the vessel suddenly rotates upside down while remaining "buoyant". To the crew, gravity remains normal, but there’s a disorienting sensation akin to being pulled toward the ceiling as if the gravity has been reversed, for this reason new pilots are recommended to travel trough Skim-space without artificial gravity.
External Appearance: From realspace, a skimming ship seems to lose part of its physical presence, with one side glowing faintly like a comet as though submerged in an invisible ocean. This glowing "underside" is random but often concentrated at the vessel's front or near its Parallel-Anchorhead (PAH). A mid-skimming vessel resembles a submarine, with antennae, secondary thrusters, or PAH systems breaching the dimensional "surface" into realspace.
Skim-Space Travel: Ships must ride the dimensional waves carefully, as larger or more erratic waves can alter their course, force emergency course corrections, or even cause catastrophic ejection into realspace. Skim-Space is treacherous near gravitational bodies, debris fields, or along busy Skim-Sign paths, where interference creates violent turbulence. Skim-Sign signals generate rhythmic pulses that travel through Skim-Space as waves. To a vessel, these waves feel like oscillations against the ship’s hull, making navigation tricky but providing an audible or visual "beat" for navigators skilled enough to use them as guides. Denser Skim-Sign traffic, like that near major communication hubs, feels like a stormy sea, forcing ships to reduce speed or risk being "capsized" by dimensional interference.
Exiting Skim-Space: As a ship approaches its destination, it must gradually slow to avoid overshooting its exit point or destabilizing upon reentry to realspace. This deceleration begins roughly halfway through the journey, where the vessel eases off its skimming velocity, activate its deceleration thrusters and rides the dimensional waves more cautiously. The transition back to realspace feels like the ship is being "righted" from an inverted position, accompanied by a noticeable lurch as gravity and dimensional forces realign. To observers in realspace, the ship appears to "emerge" like a breaching submarine, with its glowing underside fading as it stabilizes with a pop of light. This slow, careful process ensures safety and precision, which is why even advanced FTL travel remains time-intensive.
