A variation of tartana's rigging, the English sailors called it 'bean-cods', was used by the Portuguese as fishing and pilot boats.
In the bow part the vessel was extremely sharp. The stem was strongly bent inside and strengthened with iron sheets preventing the stem against clashes. The strongly inclined forward mast carried only a Lateen sail and a jib. At fishing they set a whole series of different sails, drifting under which the vessel pulled the fishnet. For maneuvering they raised or handed appropriate sails.
For example, they set two spritsails on the yards under the bowsprit. They could install a vertical spar between the bowsprit and the mast, which supported the sheet angle of a triangular sail placed between the top of the mast and the yardarm of the bowsprit, when in need. There was a long arm in the stern with two triangular sails fastened to it and to the Lateen yard. Such a strange rigging made a fine work and was a result of experience of many generations of fishermen in the mouth of the river Tezhu. Spain fishing boats of the Catalonia coast had similar placement of masts with Lateen sails but they were deprived of a bowsprit and a jib.
