What is this rot?

Posted by

What you’re looking at here is the deck of a boat having been torn up after we discovered there was rot throughout the entire hull. This kind of rot happens when water gets in through the transom or through the fibreglass on the deck. As you can see the water has spread through all of the structure with the wood just disintegrating, and the fibreglass being the only thing keeping it together… for the time being.

To prevent this kind of rotting you need to take care when adding extra fittings to your boat and when you’re maintaining your transom. When drilling holes into the deck make sure you fit and seal any fixtures to prevent water from seeping in. The rule applies for any adjustments made to your transducer or bungs. We recommend Sikaflex for a high grade marine sealant.

When conducting a safety check, we follow a procedure that ensures we check for water damage, any unsealed or poorly sealed fixtures, transom issues or integrity issues in the deck. Our specialist equipment can sense moisture through the fibreglass and indicates potential rotting or moisture in the transom and stringers of the hull. This kind of damage can be avoided by being aware of any cracking around the deck, any warping of the deck or any give in the transom structure when the motor is pushed on. The cost to replace a deck like this can be very expensive and dangerous to hull integrity and safe boating. It can be avoided by knowing the signs of water getting into your deck, such as:

-Loose or old bungs that aren’t air tight

-Loose mounting screws

-Fixtures that aren’t properly fixed and sealed

-Drilling into the deck without proper preparation or follow up

-Walking along the boat and feeling the deck warp beneath your feet

But it’s not just the deck you see here that will have to be replaced. The transom or bow structure may have to be replaced as well to ensure the integrity of the boat stays up to scratch. Repairs like this can take upwards of 4 weeks to it’s best to avoid experiencing this damage by knowing the signs of water getting into your boat, or by coming into Nautek for a service or inspection and access to our qualified Fibreglass engineering experience.

Your safety is our priority.
