Mk 1:19b ... And they-(were) in the boat down-mending the nets.

The second phrase has these 8 narrator words ... Kai autous en tōi ploiōi katartizontas ta dikta [And they (were) in the boat down-mending the nets].

The 8 words are top down. The word katartizontas, from kata (down) and artizō (mend, join, adjust) is a drawing instruction to mend the nets longer so they extend down into the sea. Only with the nets down can the gospel words be tangent to them. By calculation, the perimeter of each net (306 x 4) is 1224 units. The words tōi ploiōi (subscript i, into the boat) and ta dikta (the nets) show the words are tangent to or entering into their images.
