Hot Tub Boats Coming to Lake Union!

It's legit: Hot tub boats are coming to Lake Union

It’s true – hot tub boats could be hitting South Lake Union by the summer.

Adam Karpenske, owner of Karpenske Marine Carpentry, says he is currently working on a prototype of the boat.

Karpenske, along with his wife, Erin Kirkegaard and employee Kelly Norton have been thinking of this idea for awhile.

“It really came out of necessity. My wife and I live on a boat in Lake Union. We don’t have the space to add a hot tub on our boat so we came up with the idea to tow one from behind,” he said.

Here are the boat specs: 15 feet long by 16 feet wide. The hot tub part of the boat will be 4 feet by 8 feet and 2 feet deep. The boats will be able to hold up to 6 people.

Karpenske says the boats will be battery operated with dry storage space on board. The water for the hot tub is all fresh water, pumped into a system that preheats the water as it fills the tub.

When asked about the possibility of the boats sinking, Karpenske said, “The total buoyancy in boat itself is about 18,000 pounds. We are only loading it with 4,000 pounds of water.”

They plan to build a local fleet of four hot tub boats to be available for rent on Lake Union.

There will be a minimum and maximum hourly rental rate. Karpenske says they are still working on how much a rental will cost. But he says they already have a waiting list of people interested in renting and buying these boats once they are up and running.
