Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow.

Comparison between an axe bow (442) and a conventional bow (441) The axe bow is a wave-piercing type of a ship's bow, characterised by a vertical stem and a relatively long and narrow entry (front hull). The forefoot is deep and the freeboard relatively high, with little flare, so that the bow profile resembles an axe.
The Ulstein X-Bow (or just X-BOW) is an inverted ship's bow designed by Ulstein Group to improve handling in rough seas, and to lower fuel consumption by causing less hydrodynamic drag. [1] It is shaped somewhat like a submarine's bow. [2] Bourbon Orca anchor tug, shown in 2012, was the first ship built with an Ulstein X-Bow in 2006.
The original panga design was developed by Yamaha as part of a World Bank project circa 1970. [1] [2] [3] Pangas are commonly operated directly off beaches. [4] The name comes from the panga fish, which is commonly netted. The upswept bow of the boat resembles the machete or knife called a panga. Photo of pangas at Tiburón Island by Steve Marlett.
Watermen use these boats year round for everything from crabbing and oystering to catching fish or eels. Traditionally wooden hulled, the deadrise is characterised by a sharp bow that quickly becomes a flat V shape moving aft along the bottom of the hull. A small cabin structure lies forward and a large open cockpit and work area aft.

This shape, viewing the limbs, is designed to take into account the construction materials, the performance required, and the intended use of the bow. There are many different kinds of bow shapes. However, most fall into three main categories: straight, recurve and compound. Straight and recurve are considered traditional bows.
The Ancient Greeks used the heads of boars to symbolise acute vision and ferocity while Roman boats often mounted a carving of a centurion representing valour in battle. In northern Europe, serpents, bulls, dolphins, and dragons were customary and by the thirteenth century, the swan was used representing grace and mobility.
