Repairing local core damage
- Drill a pattern of 3/16″ diameter holes over the rotted area.

- Inject or pour resin/hardener mixture into the holes while the core is warm.
- Continue to add epoxy to the holes until the wood can no longer absorb more.
What is a bilge stringer?
Bilge stringers are used in many carvel and other round bilged hull shapes to add strength and stiffness. While smaller boats do not really need them, workboats, powerboats and others that are likely to be highly stressed often have one or more, on each side of their hull.

Can you replace part of a boat Stringer?

Why do you need a bilge pump?
This is where bilge pumps come into play. These systems help regulate the water levels inside the boat to keep too much water from gathering at the bottom. Bilge pumps are an important part of the complex structure of most boats. They are the product of an effective design to improve the safety of a boat.
