The “Hawk Tuah” phenomenon seemed inescapable across the country last year … and now we know it was even penetrating the water as well, thanks to a vessel currently for sale christened with the viral TikTok phrase.

Rob Worth, 52, a software developer in Alpena, Michigan, tells TMZ … he’s listed his 1996 Tempest 152 — dubbed “Hawk Tuah” — for $4,200.

The boat has been on sale for about two weeks … and RW tells us he has been entertaining offers — but so far, they have been lowballing him.

Obviously, the boat was getting a lot of attention out on the lake when people saw the name … and that’s all thanks to Haliey Welch and her viral explanation of proper oral lovin’.

Rob tells us he was a fan of the video … so he renamed his boat when HW’s fame caught fire.

There’s nothing wrong with the watercraft, he says … it just got an oil change and a new battery and can get up to 50 mph … RW just wants to get something bigger to cruise the lake in style.
