Hot Tub Boats is an independent business started in the Seattle Metro area. Concept, design, build and execution have all been in-house by a small, devoted team of shipwrights. We are committed to preserving our community, job growth and protecting our valuable and abundant waterways.
It all started during the cold, wet Seattle winter of 2011. Founder & creator of the Hot Tub Boat, Adam Karpenske, was aboard his house boat, desperate for the warmth and comfort that only a Hot Tub can provide. Without room to install a Hot Tub in his home he thought of a solution...
A wooden boat shipwright by trade, he put his mind to work on how he could craft a vessel that would stay hot, while still maintaining a sleek style. He drew the boat over the weekend and with the help of others, lofted the hull over the course of the following week. They then made the patterns and different sections of the boat before planking and fiberglass skinning the hull.
They launched into Lake Union the next week to double check that their calculations were right regarding buoyancy. And wouldn’t you know it, they were correct!
They took the boat back to the shop and completed the deck and the Hot Tub layout and build. They had a working prototype for a party on New Year’s Eve.
They finished the paintwork and teak decks by February and launched the business on February 16th, 2012. That Thursday afternoon was the start of something beautiful. Over the last 6 years, the Hot Tub Boat has been refined and perfected. To learn how it works, click here.
Hot Tub Boats are available for rent and purchase. Due to our design and engineering, a valid driver's license is all that is required to rent out our boats. All of our boats are custom built, in the Fremont neighborhood of Seattle.
Since our inception, Hot Tub Boats has worked closely with the United States Coast Guard to ensure we manufacture a high quality and safe boat. Our boats are carefully designed and meet the stringent U.S. Federal Regulations for Boat Builders. As a result, Hot Tub Boats are also in conformance with the European Recreational Craft Directive and we look forward to receiving the CE Mark in the near future.
