What this video covers

Orca attacks off Portugal and Spain have expanded beyond the Strait of Gibraltar to cover waters from Morocco to the Bay of Biscay, with multiple pods now operating simultaneously and striking boats even in shallow coastal waters near Lisbon.▶ 1:17 A sinking off Costa da Caparica — previously considered safe inside the 30-meter depth line — ended confidence in the shallow-water strategy.▶ 3:59 Sailing more than 10 degrees west works for passage-makers but not for coastal cruising or entering Lisbon, Porto, or the Algarve.▶ 4:24 Earlier countermeasures — stopping the boat, dumping sand or diesel, reversing, and acoustic pingers — all failed consistently.▶ 2:22 The one approach with consistent anecdotal success is deploying underwater firecrackers: a firecracker attached to a pole is submerged and detonated, causing orcas to leave without apparent injury and without leaving chemical pollution.▶ 6:57 The practice is illegal in Portugal, where the devices cannot be purchased, but firecrackers are legal to buy and sell in Spain.▶ 5:58 Chandleries in Spain reportedly now stock a dedicated kit with pole included.▶ 6:52 The crew of the 1980s ketch being refit in Lisbon frames this as information for sailors to weigh themselves, not a recommendation to break the law.▶ 7:11
