Enhance Your Yacht's Performance & Style with a Hull Extension

Considering a hull extension for your yacht? Foster’s Yacht Services is your trusted partner in the journey of yacht improvement. Hull extensions are a popular choice among yacht owners for their potential to enhance performance, increase storage, and deliver a smoother ride through the water. Our experienced team can guide you through the entire process, from design to the final gel polish.

Advantages of Hull Extensions:

  1. Improved fuel efficiency.
  2. Enhanced speed.
  3. Increased storage space.
  4. Easier steering, reducing the need for trim tabs.
  5. Minimized water intrusion over the duckboard during sudden deceleration.
  6. Quieter experience when anchored, as it reduces the sound of waves hitting the stern.
The Hull Extension Process:
  1. Initial Design: Start by selecting the style that best suits your yacht. Our experts at Foster’s Yacht Services can provide recommendations based on your preferences and needs.
  2. Concept Drawing: A naval architect will create a concept drawing based on your design choices.
  3. Review and Approval: We’ll review the concept drawings with you to ensure they align with your vision. Once approved, these drawings become the foundation for the project.
  4. Build to Scale Drawings: The concept drawings are transformed into “Build to Scale” drawings, essential for accurate bids and project completion.
  5. Detailed Quote: Request a detailed quote from your chosen contractor.
  6. Fabrication: The contractor begins fabricating templates and molds necessary to complete the extension.
  7. Certified Marine Surveyor Oversight: To maintain quality and oversight, we recommend a Certified Marine Surveyor with expertise in composite and structural fiberglass laminations to inspect and ensure the project’s thoroughness and quality at each stage.
  8. Structural Liability Considerations: Hull extensions are structural modifications with associated liability. Select a professional with the necessary credentials and a proven track record in structural tooling, fiberglass molding, fabrication and repair, and gel paint and polishing.
  9. Final Inspection and Approval: Carefully review the final report from your Certified Marine Surveyor and inspect your yacht. Once satisfied, sign off and enjoy your “almost brand new” yacht on the open water!

These guys do very good work. They repaired some fiber glass and an anchor plate along with adding a coat of paint to the hull.

We have used Fosters for years and its definitely the best company out there for fiberglass, paint and refits. Dennis is always professional and we highly recommend them for any needs in our yacht industry.

Fosters Yacht Service is my preferred company to use for yard maintenance while in Ft. Lauderdale. Dennis, Erick, and Mark know the industry and how to get things done. Fosters keeps to their word and deadline. Highly recommended.

We started with Foster’s to repair some structural hull issues. They exceeded expectations with the repairs. We also had them do multiple repairs throughout the vessel from exterior paint to interior carpentry. The fit and finish have been amazing.

As a marine industy professional it has been my direct experience to have this Group (Foster's Y/S) care for and upgrade my families Hardin 45 ketch. Everyone at Foster is a team member at Your disposal if required. We have found that Foster's high quality work in conjunction with Great customer service are the foundations found here. "Trade Winds" will be back next year for some further upgrades. Thank You for helping us sail away...

Dennis Foster and his shop are amazing. My boat had extensive fiberglass damage which was made worse by another repair shop. Dennis came to the rescue. Boat came back brand new and faster than promised. If you need any fiberglass work done, don’t go anywhere else! Thank you Dennis and team!

I brought my 2018 Formula to Dennis Foster to make my arch collapsible and make the boat able to sneak under low bridges by my house. Dennis and his team way exceeded my expectations!!! With the press of a button, my bridge clearance is now just over 6'. His work is flawless, and his team is friendly and professional. Thank you Dennis and team for the amazing results!!
