	Like sickle cells, this cell form arises as a result of altered haemoglobin solubility and the formation of long polymers along the cell length when deoxygenated.

	~~Image 1~~ Boat shaped cells. The cell body may be dense or normal, but retains central pallor. The appearance is that of a canoe viewed from above with sharpened ends an appearance reflected in the area of central pallor which also has a sharp appearance, although this may also be more slit-like in some cells. Where present the cells are generally frequent and will be accompanied by other features of the underlying abnormal haemoglobin. This may include typical sickle cells, contracted red cells, target cells or other features depending on clinical context.		'''Images''' Boat shaped cells.
