Thanks to David Hutchinson for the photo of a hovercraft-type vessel that showed up on Alki this afternoon. (Thanks also to Cami for sharing a photo via Facebook.) Not sure yet what it was up to but we’re working to find out! UPDATE: Just a few minutes after we published this, we got a note from Jeff, who says the hovercraft’s skipper was stopping for lunch but didn’t know powered craft were not allowed to come ashore; apparently the arrival sparked several 911 calls, but, Jeff says, the hovercraft’s operator “talked with SPD and was allowed to depart without further actions.” ADDED 5:31 PM: Jeff also shot and published this video – including the hovercraft rising up and heading back out onto the water:

(back to original story) Meantime, a photo from Tuesday – submarine spotted passing West Seattle shores:

Bob Anderson got the photo from his North Admiral backyard; he says the sub was heading northwest.
