At what two times were the high slack on Wednesday, February 17?

The correct choice indicates the times for high slack tide, which are essential for sailors to understand as they navigate waters affected by tidal changes. In this context, high slack tide refers to the points in time when the water is at its highest and moments before it begins to ebb or flow out, making it crucial for planning safe and effective sailing trips.

For February 17, the high slack tide occurs at 02:25 and 12:32, as indicated in the chosen option. Tidal fluctuations are typically predictable and can be found using tide tables or specific tidal charts for the area. Knowing the exact times of high slack helps sailors avoid difficulties in navigating shallow waters or strong currents that may be experienced just before or after the tide changes.

The other choices may represent times pertinent to low tides or other tidal phases that do not correspond to the high slack period. Thus, selecting the times that reflect the high slack on that specific day ensures alignment with the tidal patterns, which is crucial for ensuring safe sailing practices.
