🔍 Key Concepts

• Perigee full moon effects on tidal currents (springs vs neaps) • How to use the Tidal Current Tables (Nantucket Shoals reference station) • Relationship between range of tide and maximum current speed at a strong off‑soundings area like Nantucket Shoals

💭 Think About

• Think about whether a full moon at perigee produces weaker, average, or stronger than average currents, and how that would affect the maximum speed you’d expect. • Ask yourself what kind of current strengths are typical on offshore shoals near major tidal inlets—are they usually under 1 knot, around 1 knot, or several knots at springs? • Consider whether 2350 (ZD +5) is close to a predicted time of maximum flood or ebb at this location in the tables, or closer to slack—how would that change your choice?

✅ Before You Answer

• Verify whether a perigee full moon corresponds to spring tides (strong currents) or neaps (weak currents). • Check the predicted maximum current for a spring phase at Nantucket Shoals in the Tidal Current Tables, not just an average day. • Confirm that your selected value makes sense for a maximum current at a shoal area known for strong tidal streams—avoid values that seem unrealistically low for that description.
