Houthi military spokesman Yahya Saree made two separate claims on Wednesday 5 August: a ballistic-missile strike on the tanker Wafaa off Yanbu on Saudi Arabia's Red Sea coast, and a strike on the tanker Daisy in the Gulf of Aden1. Several wires merged them into a single vessel of disputed name2. Yanbu and the Gulf of Aden sit more than 800 nautical miles apart, at opposite ends of the Red Sea, so evidence for one strike is no evidence at all for the other.
UKMTO (United Kingdom Maritime Trade Operations), the Royal Navy cell to which merchant captains report incidents at sea, recorded one event: a loud explosion 95 nautical miles south-east of Aden at 14:30 UTC, crew accounted for, no environmental impact3. As of Thursday 6 August its record held nothing matching the Yanbu claim. A UKMTO log entry and a Saree announcement carry different evidential weight. A master reporting to UKMTO is describing something that happened to their own ship; a belligerent announcing a hit has every reason to claim ones it did not land. Cutting the other way, vessels in this corridor routinely run dark or decline to report, so an unlogged claim is weaker evidence of nothing having happened than an absent satellite fire signature would be. The Yanbu claim should be held open, not dismissed.
Naming the vessel rests on thinner ground still. The open-source analyst AtlasObserver tentatively named the Gulf of Aden vessel as the Dominica-flagged product tanker Daisy, International Maritime Organization (IMO) number 9516545, and no flag state, owner, insurer or official body has confirmed it4.
The "eighth tanker since 22 July" figure now circulating is the movement's own running count, not a verified total, and that distinction carries a price. War-risk underwriters set premiums off demonstrated capability, and the Houthis have moved rates before by announcing intent, widening their target set to Yanbu and Jazan Aramco sites in late July and claiming strikes on crude transport infrastructure days later. An unverified claim, repeated widely enough, costs shipowners money whether or not a missile ever flew. Riyadh struck Houthi-held military sites near Hodeidah after the NCC Masa was hit off Al-Shuqaiq in July, which is what turns a second unconfirmed claim into something more consequential than a bookkeeping dispute.
