🔍 Key Concepts

• Flood vs. ebb tide and how they affect a vessel heading seaward or landward • How long it takes to travel from the entrance of Delaware Bay to Marcus Hook at 15 knots • Using the favorable current for the maximum portion of your transit and during docking

💭 Think About

• First, decide whether you want the flood helping you more in the Bay, in the River, or mainly right at the dock when landing starboard side to, heading seaward. • Estimate the transit time from the Bay entrance to Marcus Hook at 15 knots and compare that with the typical 6‑hour tidal cycle for flood or ebb. • Think about whether arriving too early in the cycle would cause you to have adverse current either during the trip up the Bay/River or during your final approach to the berth.

✅ Before You Answer

• Verify how flood current direction behaves in Delaware Bay and up toward Marcus Hook (does flood set you up-bay or down-bay?). • Check whether timing arrival before a tidal phase versus after a tidal phase gives you more hours of favorable current for both the transit and docking. • Confirm that your chosen option allows the current to be on your bow or helping your approach during the actual docking maneuver, not just en route.
