Axe bow

Wave-piercing type of a ship's bow

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. The forefoot is deep and the freeboard relatively high, with little flare, so that the bow profile resembles an axe. The bow cuts through the water, and is less affected by passing through waves than a bow with more flare, making this bow type much less susceptible to pitching. Because the deep forefoot does not generally rise above the water level, it is less susceptible to slamming. The axe bow moves the centre of lateral area forwards and the vessel may need considerably more rudder motion to hold its course, and this increases with the wave steepness.
