Contracts on this passage

Everything above counts what already happened. These are the only figures on this page about what happens next, and nobody wrote them — the market did. Each is the price of a contract on this passage's published weekly transit count, and it moves while the market is open.

A price is what people here are paying to take that side. It is not a forecast and not an official figure. The count for a week is published a few days after the week ends, so these markets settle after their window closes.

These distances are worked out from the shape of the passage itself, not quoted from a reference. The clear-water figure is the widest lane that fits between the shores along the whole corridor. That comes out narrower than the headland-to-headland width an atlas prints.
