This comic seems imply that ebb and neap are opposites of or compliments to each other. They are not.
Ebb means the tide is going out (from high tide to low tide). In most areas that have tides, the tides ebb and flow (rise and fall) approximately 2 times per day. All tides (including neap tides) have ebb and flow to them.
Neap tide refers to the times (twice each month) when the difference between high tide and low tide is the least – the high tides are at their lowest (do not get very high) and the low tides are at their highest (do not get very low). This happens at approximately the quarter moon phases when the sun and moon are pulling on the earth at right angles to each other.
Twice each month, at Full Moon and New Moon Phases the sun, moon, and earth are aligned and the sun and moon’s pull on the earth’s water is “magnified” and you get the highest high tides and the lowest low tides. These are referred to as Spring Tides.
