__NOINDEX__ See User:Geo Swan/Stale drafts The inverted bow is an alternative design for the stem of large surface vessels.

The most popular stem design for warships and merchant vessels has slender "V" shaped clipper bow above the water, balanced by an underwater bulb at the keel level. The slipper bow has a sharp or relatively sharp leading edge, that slopes outwards.

Inverted bow designs slope inwards.

One variant of the inverted bow is the Ulstein X-bow. With the X-bow the leading edge is curved in both the horizontal and vertical directions. From keel to deck the stem resembles a broad semi-circle. The manufacturer claims vessels built to this design will consume less fuel, will be faster, and more stable.
