29 SVN Solovelanet Global T he curiosity of orcas towards sailboats is nothing new. In recent months, several at- tacks have been brought by these massi- ve cetaceans against sailboats, for exam- ple in front of the Atlantic coasts of Spain where even the Coast Guard issued an orca alert, so much so that there has been talk in the media, even outside the sector, of a real 'orcas case'. In particular, some British newspapers have mentio - ned "killer whales" "hunting for blood", treating the news with the usual stereotypes that are too often used about these animals. As usual, it is science that can clarify these phenomena. Having examined the recent cases of attacks by orcas against sailboats to - gether with other marine biologists, the orca expert Ruth Esteban has given a concrete explanation. "We can state that it is a game ritual" - said Esteban. - We have observed how orcas almost always hit the rudder, and this is no coincidence. It seems likely that they realized that hitting the rudder causes the boat to move, and this might excite and thrill them. This is a show of strength that orcas perform against what might look like another fish to them - continues the expert. - In their behaviour there is no predatory inten - tion, otherwise their movements would be completely different from what we have seen." So there are no killer whales: there are just animals facing objects that do not belong to their environment, such as boats, but bear a certain resemblance to one of their kind. The curiosity of orcas towards sailing boats is well known and certainly not recent, given that episodes of this kind have always occurred. In this iusse of SVN Global, we interviewed Giorgio Di Mola who over forty years ago experienced the shipwreck of the Guia III rammed by an orca in the middle of the Atlantic.
