When boating on coastal waters it is important to be aware of the tides why?

Boat operators in coastal waters should be watchful, mindful and careful of the effects of tides when boating, because the rise and fall of tides in the water can cause water levels to fluctuate and change by several feet and can possibly create strong currents in which tidal currents are strong enough that makes the boats cannot make successfully heading against the current.

Answer: Tides cause water levels to rise and fall.

Explanation:

When boating in coastal waters one must have the effect of tides in mind. Usually, changing tides are predictable, as variations commonly appear twice every day at around six-hour intervals. The rise and fall of tides can change water levels by a lot, and strong currents may also develop. Tidal currents can get so strong that a boat may not be able to make headway against it.
