How to determine if a fiberglass boat is waterlogged?

If you are thinking of purchasing a used fiberglass boat, it is important to make sure that it is not waterlogged. A waterlogged boat can have hidden damage that can be costly to fix, and can also affect its performance and safety. Here are a few tips on.

1. Check the weight

A waterlogged boat will be heavier than it should be. When you board the boat, pay attention to its weight. If it feels heavier than it should, it could be an indication that water has made its way into the hull. If the weight seems to be the same or slightly lighter, then it’s probably not waterlogged.

2. Inspect the hull

To check for water penetration, inspect the boat’s hull – both inside and out. Take note of any cracks, chips, or punctures along the surface of the fiberglass. If there are any cracks or damage, it could allow water to seep into the core of the boat. Look for any evidence of water damage, such as soft spots, separation of layers, bulges, delamination, or mold on the hull. This could indicate that the boat has absorbed water and may have become waterlogged.

3. Observe the drainage system

Check the boat’s water drainage system to ensure everything is working properly. A boat with a functioning drainage system will allow water to easily move out of the hull. Check the bilge pump for any signs of rust or leaks, and make sure to turn it on to ensure it works well. If water is not draining properly, it could indicate that the boat is taking on water more rapidly than it can expel it.

4. Seek professional inspection

Finally, the best way to determine if a boat is waterlogged is to have it professionally inspected. A trained boat inspector can assess the boat’s overall condition, including identifying any hidden water damage. They will use specialized equipment, such as moisture meters, to detect any water penetration in the fiberglass of the boat.

Buying a waterlogged boat can be a costly mistake. Always take the time to inspect a fiberglass boat thoroughly before purchasing, and look for signs of water damage as well as using professional help to verify the purchase. By checking the weight, inspecting the hull, observing the drainage system, and seeking professional inspection, you can ensure that your boat is in good condition and will serve you well for years to come.
