How are boat stringers fixed?

Boat stringers are essential components of a boat’s structural integrity as they provide support and distribute weight evenly along the hull. They are long, narrow wooden or fiberglass beams bonded to the hull and run parallel to it. Over time, due to wear and tear and exposure to harsh marine environments, they may get damaged and require repair or replacement.

Here are the steps involved in fixing boat stringers:

1. Inspect the stringer: The first step in repairing a boat stringer is to assess the damage. Check for any cracks, soft spots or rot on the surface. Also, determine whether the stringer is adequately secured to the hull and has not come loose.

2. Cut out the damaged section: Once the damage is identified, the next step is to cut out the affected section of the stringer using a saw.

3. Remove the debris: Once the damaged section is cut out, remove any debris or moisture from the hull and stringer, particularly in the area where the new section will be installed.

4. Prepare the new section: The new section to be installed should be of the same type of material and size as the original stringer. Cut it to the required length and shape and prepare it for bonding.

5. Secure the new section: Apply marine-grade adhesive to the underside of the new section and place it in the cut-out area of the stringer. Hold it firmly in place using clamps or weights until the adhesive sets.

6. Laminate the repair: Once the adhesive has dried, laminate the joint using fiberglass or carbon fiber strips. Laminate tightly, ensuring that there are no air pockets or wrinkles in the laminate.

7. Reinforce the stringer: In some cases, it may be necessary to reinforce the stringer by adding additional layers of fiberglass or carbon fiber above and below the repair area.

8. Finish: Sand the repaired area until it is smooth and level with the surrounding surfaces, then paint or gelcoat it to match the rest of the boat.

It is important to note that repairing or replacing boat stringers is a job that should be carried out by an experienced boat repair technician or boat builder. Failure to do so may result in further damage to the boat and compromise the vessel’s safety. Regular inspections and maintenance can prevent the need for major repairs and prolong the life of your boat stringers.
