A fifty-year-old fiberglass boat can potentially be seaworthy and safe, but its structural integrity depends entirely on the quality of its original manufacturing, environmental storage history, and the extent of previous maintenance. Over decades, older fiberglass hulls can suffer from hidden structural issues such as transom rot, stringer degradation, and a condition known as hull blistering or water saturation in the core materials. Before taking an antique vessel on the water, a comprehensive inspection by a certified marine surveyor is essential to verify structural safety.
