{{Short description|Hull with fine bow with reduced reserve buoyancy}} thumb|{{MY|Ady Gil}} in 2009 [[File:HMNZS Aotearoa.png|thumb|{{center|HMNZS ''Aotearoa''}}]]
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 means the hull pierces through the water rather than riding over the top, resulting in a smoother ride than traditional designs, and in diminished mechanical stress on the vessel. It also reduces a boat's wave-making resistance.
The physics of wave-making resistance calls for very long thin hulls, so in practice most are multi-hulls such as catamarans and trimarans.
