Brian Hooker calmly … very calmly … explained what happened to his wife just days after she went missing near the Bahamas in a new video obtained by TMZ.

The clip — taken on Monday, April 6 — two days after Lynette disappeared and two days before Hooker was questioned by the Royal Bahamas Police Force — shows a fellow seafarer engaging in a conversation with Hooker.

The two have a conversation from their separate ships … with Brian standing on “Soulmate.”

He explains Lynette went over the side of the boat the other night … before he paddled over to a nearby island. We know he previously told a friend the two were separated due to high winds.

The fellow boater says they’ll be around if Hooker needs anything … and he says he may need help with his anchor — because he’s never brought it up on his own.

The person Hooker is talking to tells him he’s sorry about the situation … but Hooker seemed to be mostly focused on getting out of the area.

Hooker previously said he and his wife were taking an 8-foot dinghy to pick up Soulmate, but they hit rough weather during the trip and Lynette went overboard while wearing a lanyard with the boat’s keys, causing the boat to stop. He says he had to paddle it to shore.

As we said … investigators talked to Hooker later on — but reportedly told him he wasn’t a suspect in his wife’s disappearance. He’s since left the island … hightailing it out of the area to check on his ailing mom.
