Hull with fine bow with reduced reserve buoyancy

[MY *Ady Gil*](/source/MY_Ady_Gil) in 2009

[HMNZS *Aotearoa*](/source/HMNZS_Aotearoa)

A **wave-piercing** boat [hull](/source/Hull_(watercraft)) has a very fine [bow](/source/Bow_(watercraft)), with reduced [buoyancy](/source/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](/source/Stress_(mechanics)) on the vessel. It also reduces a boat's [wave-making resistance](/source/Wave-making_resistance).

The physics of [wave-making resistance](/source/Wave-making_resistance) calls for very long thin hulls, so in practice most are multi-hulls such as [catamarans](/source/Catamaran) and [trimarans](/source/Trimaran).

The main current usage areas are passenger [ferries](/source/Ferries)[1] and [naval ships](/source/Naval_ship).[2]
