A Blank Canvas
My journey to starting a design and restoration company
By Jake Thimmesch-Slepica
I have always had a passion for the water. I grew up in Minnesota, the Land of 10,000 Lakes, where every weekend we would go “up north.” I learned the joys of water skiing, tubing, and wakeboarding. My family started out with a Weeres pontoon, where you had to bring your own lawn chairs. Then we upgraded to a ‘97 Four Winns Fish and Ski. When I was 15, I was diagnosed with non-Hodgkin’s lymphoma and was blessed with a Make-A-Wish. My wish was for a Sea-Doo RXP. As I got older, I would go to the family cabin by myself, even if my family couldn’t make it. Everything was centered on getting more time on the water.

My love for art led me to school at the College for Creative Studies in Detroit, Mich., where I majored in Transportation Design. Out of college, I landed a dream job at General Motors as a digital sculptor for the Cadillac Studio. But after a few years, the passion just was not there for me. I needed to get back into what I truly loved: the marine industry. My fiancée and I moved down to Abilene, Texas, where I started my new career with Tige Boats. I loved working with that crew and got to design some of the coolest boats in the industry. However, life happens, and as my family grew, we decided to move back to Michigan to be closer to my wife’s family. I was able to get a job with Manitou Pontoon Boats and really enjoyed the challenge of designing for the pontoon industry. You wouldn’t think that it would be that difficult; it is just some couches on a platform, right? The real challenge is designing different layouts for different models in multiple lengths while balancing configuration, ease of production, and allowing the customer the freedom to create the boat for them.

Then Covid happened.

I had to evaluate what I wanted in the next steps of my career. I decided to take a leap of faith and launch Slepica Studio. The mission is to design and customize boats, not just for the OEMs, but directly for the customer. I wanted to use my industry knowledge and supplier connections to create quality custom boats.

Show Boat
To showcase what the studio could do, I needed a blank canvas. I found a 1992 American MFG Raven pontoon on Facebook Marketplace for $1,200. The previous owner claimed it “floated and ran,” but in hindsight, I probably should have verified that before handing over the cash. Instead, I dove headfirst into what would become the “Raven Project.”

I later discovered that the Raven brand originally operated out of Alma, Mich., and had long since gone out of business. My goal was to bring this forgotten model back to life with modern touches and a unique aesthetic that still complemented the boat’s original lines.

I started, as I do with every professional project, with a sketch. It took a few ideations before I landed on a vision that I liked. Sketching it was the easy part; now I had to figure out how to actually build it. I was always a visual person, but never had the hands-on mechanical experience. So, I did what many other passionate DIYers do: I dove in and figured it out as I went.

Getting Started
The boat was gross, really gross. It had been sitting outside for far too long with things growing and funky smells. Before I could do anything structurally to the boat, I had to clean it. I found a pontoon polishing kit from Renegade Products and right in my front yard, began cleaning up the pontoons. The HOA did not care for that setup, forcing me to clear out the garage. If I turned the motor completely sideways, I could just close the garage door, so this was a big win.

Next came the teardown process, documenting everything along the way. Bolts, wires, and any old parts were labeled and organized. The seats were falling apart, the foam was crumbling, the wood was waterlogged, and the floor was peeling away. The walls and Bimini frame were shipped out for powder coating. Everything was brought down to the aluminum frame so I could build it back up.

Interior Touches
To rebuild the interior, I ordered replacement seats from PontoonStuff. Because the Raven’s original rear seat bases were molded fiberglass and still structurally sound, I modified the new seat cushions to adapt seamlessly to the vintage bases. PontoonStuff also supplied the floor-replacement essentials, but I used my industry supplier connections to source a specific woven vinyl flooring in the exact color palette I envisioned.

For the fabric elements, I went custom. I selected a classic houndstooth pattern for the Bimini canvas and carried that motif into the throw pillows and custom wall graphics, tying the entire design aesthetic together. I preserved the original fiberglass helm structure but modernized it with a new steering wheel, a custom center cap wheel emblem, integrated wireless phone charging, and crisp marine rocker switches.

Adding Tunes To The `Toon
For entertainment and safety, I rewired the entire vessel, adding a Fusion sound system with four 6.5-inch speakers, a 10-inch subwoofer, and a full LED lighting package (navigation, anchor, docking, courtesy, and rub rail lights). Finally, I modernized the classic Raven logo for the walls and helm.

The original 25hp Mercury outboard surprisingly didn’t need a total overhaul. With a little Sea Foam motor treatment, fresh spark plugs, and clean gas, she purred back to life. I painted the engine cowling and applied fresh graphics that perfectly matched the exterior wall wrap. This wrapped it up and made it feel like a brand-new modern pontoon that could still be around today.

The Final Touches
It is the details that will set your project apart from the others. I had a vision and goal from the beginning that kept my project on track, but as I went along, there were small things I had to add or adjust to keep it moving forward. I learned a lot from this project, and it opened me up to what I was capable of. Working on this also helped how I approach boat design with my OEM clients. I learned how certain things go together, the timing, the logistics, and the proper steps to actually build a boat.

This was a “budget” project, and I have since sold it to the Keller family in Ohio. I have continued to upgrade my boats just about every year and add my own touches to make each one unique.

Recently, I accepted a full-time position with my long-term client, Avalon Pontoons, but I continue to support custom builds for retail customers through my studio in White Lake, Mich. I love helping all of my clients design and build the exact boats they want. Because at the end of the day, we aren’t just building boats—we are building the platforms where families create lifelong memories.
