Under the influence of alcohol, the eyes may not work in tandem. This affects depth perception and, in more pronounced instances, may cause double vision. Drinking also reduces your peripheral vision. A drinker s vision becomes blurry and unfocused. After consuming alcohol our sense of balance is affected, making it harder to control a personal watercraft and making you more likely to fall off.
Coordination suffers, again making it more difficult to operate a watercraft.
If you do fall off, you ll even have a harder time getting back on. Drinking causes blood vessels in the skin to dilate. This can lead to a feeling of warmth, but it actually allows body heat to escape more rapidly, increasing your chances of hypothermia. Drinking only beer won t keep you safe. One beer, one glass of wine and one mixed drink typically contain about the same amount of alcohol.
