boiler and an adjustable thermostat that can keep the water hot in a winter rainstorm. Each Hot Tub Boat is handcrafted in Seattle by devoted shipwrights. Their custom design allows for anybody with a valid ID to rent. This is because their custom engineered electric motors do not allow the boat to exceed 5 mph. The Hot Tub Boat is navigated by joystick and is extremely easy to use. The teak decking is extremely stable, allowing for occupants to lounge on the decks when they please. The onboard, dry storage hatches allow for people to bring out food or drink, and each Hot Tub Boat rental also gets sent out with a waterproof Bluetooth speaker.

As their own captains, boat renters decide where to go. Maybe they will take their hot tub cruising underneath the I5 bridge into Portage Bay, or perhaps they will head down to South Lake Union underneath the seaplanes, viewing the beautiful houseboats as they go by.

Last summer, customers also went on excursions during the historic heat wave and kept the waters chilled. Each boat has a six-person maximum and rents for $441 for 2 hours.

Boats are also available for purchase, so if you have a spare $75,000 lying around, you can get your own.
