When estimating distances on the open-water, a person would likely be gazing across a relatively featureless watery landscape. The aim of this article is to examine the effect of vantage point and the influence of perceived effort (swimming) on distance estimations. To examine the effect of vantage point, 22 participants made several distance estimations in the harbour from two perspectives: 1) from shore out to a boat and 2) from a boat back to the shore. To examine the effects of the swim, each participant was asked at several distances to estimate the distance back to shore. At the end of this session the boat stopped around 400 meters from shore, participants had to climb into the water, estimated the distance and swam back to shore. Results showed that distance estimations from boat to shore were significantly more accurate than from shore to boat, distance estimations were generally underestimated. Distances <100 meters were significantly more underestimated than distances larger than 100 meters. When people do not have to swim they make significantly larger underestimations than when they are aware that they do have to swim. While immersed in water at the beginning of the swim, participants overestimated distances. Together, this illustrates that an effect of vantage point was observed on the accuracy of distance estimations. It remains to be explored what environmental properties influence the underestimation of distance over water. Furthermore, people perceive the surrounding environment in terms of their ability to swim in the cold water. Keywords: visual perception; perceived effort; performance; environment; water
