WavePiercing...
A wave-piercing boat hull has a very fine bow,
with reduced buoyancy in the forward portions.
 
When a wave is encountered, the lack of buoyancy makes the hull
pierces through the water rather than riding over the top,
resulting in a much smoother ride than traditional designs,
and it largely diminished mechanical stress on the vessel.
​
It also reduces a boat's wave-making resistance,
and the design theory calls for very long thin hulls.
 
Flow...
Flow in positive psychology, also known colloquially
as being in the zone or locked in.
​
It is the mental state in which a person performing some activity
is fully immersed in a feeling of energized focus, full involvement, and
enjoyment in the process of the activity.
​
In essence, flow is characterized by the complete absorption in what one does,
and a resulting transformation in one's sense of time.
 
Glider
Glider is the agent noun form of the verb to glide.
It derives from Middle English gliden,
which in turn derived from Old English glīdan.
 
The oldest meaning of glide may have denoted as a very smooth motion. ​
Gliders benefit from producing very low drag for any given amount of lift.
