Some activities organised by the Itsasgileak project were added to the official programme of the Sagardo Apurua 2015, in order to publicise the history of Basque shipbuilding and disseminate the Basque Country's maritime heritage. On the 21st, some traditional fishing boats sailed from Astigarraga and Pasaia and, this way, represented the transportation of cider, emphasising the importance of the river as a means of transport. The ships docked at the Urumea river, and they were on display between the Santa Catalina and Maria Cristina bridges for a week. Afterwards, on the 27th, they sailed to Pasaia. On December 26th, they showed the traditional process of unloading cider casks. They took the casks from a side (of the river boat) to the ox cart and, afterwards, they carried them to Constitution square. That day the ‘Albaola zure plazan’ exhibition started: They showed the process to build the replica of the San Juan boat and, that way, there was the chance to get to see in great detail the manual labour involved in making part of the whaling vessel. This little workshop was open to the public for four days, at the Boulevard. On December 27th, there was a workshop for children. With the help of a guide from Albaola, they built small whaling vessels with the corks from cider bottles.
