Houthi "Blow fish" low-profile explosive boat found in Red Sea SLOC
A second Houthi Blow Fish unmanned low-profile explosive boat has been found in Yemen (Press release). The type was first reported in September 2018 suggesting serial production of this model.

Trivia: note music the pun in the name... "Hootie and The Blowfish"

These craft are likely operating from Houthi controlled coast on the Yemeni side of the southern Red Sea. Their small size means that it can be built inland or in hiding and launched from a trailer across an isolated beach in the sparsely populated area, requiring minimal infrastructure and reducing the risk of detection. As a practical consideration, the large hull openings allow the explosive payload to be loaded only when it’s in the water. They could also conceivably hide these vessels among the numerous small boats in one of the few fishing communities along the coast.

The Blow Fish is likely to be launched with a two-person crew aboard, and escorted by another small vessel. Once the vessel is in a waiting position near the shipping lanes the crew would cross to the support boat and leave the vessel drifting. Possibly the GPS or radio navigation equipment allows some level of automated position-keeping, or more likely external commands are needs to keep the vessel in a useful position. It is not clear how it is brought on to a target, but the Houthis likely use a combination of AIS (Automatic Identification System – the navigation broadcasts made by commercial vessels for safety reasons) and shore-based surveillance. Or possibly the second boat is used to command the LPV.

The Houthis are also likely to receive intelligence from the Iranian support vessel Saviz near-permanently anchored on the opposite side of the shipping lanes nearer to Eritrea (at 15.8689 N, 41.1344 E).
