We leverage a wealth of expertise and cutting-edge technologies including digital scanning, CAD, laser etching, and CNC routing to create truly customized SeaDek flooring installations.

How to get started on your SeaDek project

1. Precise Measurements

We use digital scanning technology to ensure precise measurements of your boat. Our Certified Installers can come to you and scan the boat while it is in the water or on land. With our extensive catalog or in-house scans, we guarantee accurate and tailored results.

2. Computer Modelling the Design

We use computer modeling (CAD) to design the SeaDek covering specifically for your boat. By incorporating your desired color schemes and patterns, we create a customized solution that fits your boat's measurements perfectly.

3. Customizing Your SeaDek

We bring designs to life with state-of-the-art CNC routing, intricately cutting and patterning SeaDek material to match your design. Laser etching and engraving services add personalized touches.

4. Professional or DIY Installation

For a professional finish, we can install the SeaDek with your boat in the water or on land; our Certified Installers are completely mobile. Alternatively, you can install it yourself with our instructions and support.

Different ways to get your SeaDek

  • Turn key service: have a certified installer come to you and digitally scan your boat
  • Use one of our thousands of designs on file
  • Create a plastic template
  • Same day scan and install at our facility

Yousef Hana

Thomas Custom Marine is absolutely incredible.. I called on Monday morning for a quote, stopped in picked out my flooring and was told my boat could be done on Wednesday. Received a call before supper Tuesday and was told I could drop my boat off anytime and get it back at 12:00 noon Wednesday. Done & Done right on time and was totally thrilled and absolutely impressed with the job Chad had done on my floor. The cresting was just insane and I could never have ask for a better job, nor timing. Thank-you very much for Thomas Custom Marine/SeaDek for your professionalism and overall talent!!! One super impressed and happy Customer/fisherman here... :)

I just had my 45’ yacht done with Chad at Seadek. Chad done an amazing job. He is a perfectionist and from start to finish he was in constant communication with me and got the job done exactly on time and and exactly as quoted even though there was a bit more material required and a couple of late design changes I requested after he had already cut the material. I would highly recommend Chad and the Seadek product. It turned out even better than expected. Once again Thanks Chad!!!
