What precaution should a boater take when securing their vessel at a dock?

When securing a vessel at a dock, it's crucial to ensure that the lines are long enough to accommodate tide changes. This precaution helps maintain the stability and safety of the boat as water levels fluctuate. If the lines are too short, they may become taut or even snap during high water conditions, putting the boat at risk of damage or causing it to break free. Longer lines allow for the natural rise and fall of the water, preventing unnecessary strain on the dock lines and ensuring the vessel remains securely tied.

While using only one line for mooring might seem sufficient initially, it does not provide adequate support, especially if the vessel shifts due to wind or currents. Leaving engines running is generally discouraged as it can be a safety hazard and create unnecessary noise and pollution. Consulting with other boaters for docking help can be beneficial, but the primary focus should still be on ensuring that the vessel is properly secured for changing water conditions. Thus, having properly measured lines considering tide changes is fundamental for safe boating practices.
