The size of the water area in which you intend to ski determines the number of boats and skiers that can operate within it at the same time. Allow for a margin of safety against hitting bottom or submerged obstacles during a fall. Serious injuries can result from hitting fixed objects such as docks, pilings or stumps. While many areas with obstacles are marked by warning buoys or signs, it is up to the boat operator, observer and skier to be alert to any potential hazards in the skiing area. Avoid solid objects when landing.
Many serious injuries occur when skiers attempt to stop near docks or pilings.
As a rule, avoid skiing when the water is rough due to high winds. Choppy water demands a greater skill level and causes the skier to fatigue more quickly, often because the tow boat cannot maintain a constant sped. Skiing in the rain is not recommended because of the loss of visibility experienced by the boat operator. When skiing in cooler weather, be aware of the effects of hypothermia. Loss of body heat leads to a reduction in coordination and judgment.
