From 1333, Francesco delle Barche of said arsenal, who became known for the mechanical shovel with which one could clean the bottom of the Venetian lagoon, was responsible for the port expansion. [13] His report, which is extremely difficult to interpret, has been preserved. The pier was 270 m long, the passage to the port was 60 m wide, with the port wall running from southwest to northeast due to the strong winds from north-northwest in winter, just like at the Muslim port before. However, this port had become too small, so that Francesco had it expanded by more than 26 m to the northeast in a semicircle. For this purpose, an almost 140 m long breakwater was placed in front of it. But this new, northeastern breakwater proved to be unstable and collapsed in the middle of the 14th century. At the same time, Francesco had to constantly dredge the harbor, which threatened to silt up with sand from the inflowing streams and sea sand. The sand was sold, but he underestimated the influx of sand from the Dermata, one of the six streams around Candia, just as the Muslims had done. On the contrary, this silting up could explain why Candia did not have a significant port in the Muslim era and why it was not in use during the brief reign of the pirate Enrico Pescatore from 1207 to 1209.
