A '''wave-piercing''' boat [[Hull (watercraft)|hull]] has a very fine [[Bow (ship)|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 [[stress (mechanics)|mechanical stress]] on the vessel.  It also reduces a boat's [[wave-making resistance]].

[[Wave-making resistance|Design theory]] calls for very long thin hulls, so in practice most are multi-hulls such as [[catamaran]]s and [[trimaran]]s. 

The main current usage areas are passenger [[ferries]]<ref>{{cite web |last1=Tarantola |first1=Andrew |title=Monster Machines: The World's Fastest Boat Is Basically An Aquatic Concorde Jet |date=29 June 2013 |url=https://www.gizmodo.com.au/2013/06/monster-machines-the-worlds-fastest-boat-is-basically-an-aquatic-concorde-jet/ |publisher=Gizmodo |accessdate=7 June 2018}}</ref> and [[naval ship]]s.<ref>{{cite web |title=Rolls-Royce wins first Environship order |url=https://www.marinelog.com/index.php?option=com_k2&view=item&id=1415:rolls-royce-wins-first-environship-order&Itemid=257 |publisher=MarineLog |accessdate=7 June 2018}}</ref>
