Μετρώντας το άνοιγμα των σκαλμών...

Όπως λέει και ο Mike, "Span is really not very helpful without also knowing the spread", αλλιώς θα γίνουν οι σκιφίστες σας, σαν τενίστες!

Scullers . . . this one is for you!

In sculling span is a very critical measurement. It tells the distance between the port and starboard pins. This is an important dimension of determining the leverage of the boat (how heavy or light it will feel).

Many scullers just stop once they get their span measurement, but there is a need to go one step further. The distance of the pin from the centerline of the boat needs to be equal on both sides.

In other words:

Span is really not very helpful without also knowing the spread.
