B-Quiet Ultimate : Your Solution to Tranquility

B-Quiet Ultimate is a revolutionary product designed specifically to address the noise challenges in Bertram 35 boats. This high-performance sound deadening material is engineered to provide significant noise reduction, cutting down engine sounds by 10 to 15 decibels. Its lightweight yet highly effective composition ensures that you enjoy a quieter ride without adding substantial weight to your boat.

Simple Installation: Empowering the DIY Enthusiast

Installing B-Quiet Ultimate is a straightforward process, making it ideal for DIY enthusiasts. The product comes in convenient, self-adhesive sheets that can be easily applied to all metal surfaces within the Bertram 35’s engine compartment. The installation process involves:

  1. Preparing the Surface: Ensure the engine compartment surfaces are clean and dry for optimal adhesion.
  2. Cutting to Size: Measure and cut the sound deadening sheets to fit the contours of your engine box.
  3. Application: Peel off the backing and firmly press the sheets onto the metal surfaces, smoothing out any air bubbles.
  4. Sealing Joints: For enhanced insulation, cover all joints and seams with the sound deadener to minimize air and water vibration.

How Much Material Do You Need?

A Bertram 35 typically requires 150–200 sq ft of sound deadening material for full coverage, depending on how many surfaces are being treated (engine room, bulkheads, cabin, hull, etc.). The actual required area could be significantly lower or higher depending on what you treat. 

 Using Ultimate to control panel vibration and VComp barriers to block low-frequency engine and generator noise gives the best results. This investment not only enhances your boating comfort but also adds to the overall value of your vessel.

Benefits for Bertram 35 Owners

  • Quieter salon & stateroom: better conversations, music, and sleep.
  • Reduced fatigue: less vibration on long offshore runs.
  • Improved resale value: noise-controlled boats appeal more to buyers.
  • Charter advantage: guests enjoy a smoother, quieter experience.

Conclusion: Embark on a Quieter Nautical Adventure

The Bertram 35 is a legend strong, fast, and luxurious. But even a boat with this pedigree benefits from targeted sound deadening. By treating the engine room, bulkheads, cabin floor, and hull, you’ll dramatically reduce noise and vibration, creating a more comfortable experience for fishing trips, cruising, or family getaways.
