Background
Charles Ryan purchased his boat in 2022, inheriting a recently antifouled hull from the previous owner. The antifouling was applied in August 2022, but the boat remained in the water without maintenance throughout the following year.
By early spring 2024, the boat was hauled out for inspection.
The Problem
On lifting the boat from the water in March 2024, Charles was met with a heavily fouled hull, densely covered in small barnacles. Attempts to remove them with a brush proved difficult. In one instance, the force required caused the plastic brush head to invert, chipping parts of the GRP (Glass Reinforced Plastic) hull in the process—necessitating minor hull repairs.
The Solution
After completing the repairs, Charles applied a single coat of Teamac Antifouling D Plus directly to the hull. No primer or undercoat was used.
Â
The boat was then returned to Bridlington Harbour, where it remained moored in saltwater, resting overnight in slings during transitions.
The Results
After one full year in the water—from March 2024 to March 2025—Charles once again took the boat out. The result?
"There wasn’t a barnacle on the boat."
Only a light green residue was observed above the antifouling line (the boottop)—a minor aesthetic issue easily remedied by using Teamac Antifouling A Type in white for the boottop.Â
The hull itself required nothing more than a straightforward clean using a power washer. No scrubbing. No damage. No fouling.
Conclusion
This case clearly demonstrates the outstanding performance of Teamac Antifouling D Plus in preventing marine growth over a 12-month period. With minimal effort and a single coat, Charles’s boat stayed barnacle-free and required only the simplest maintenance.
For boat owners operating in similar marine environments, Teamac D Plus proves to be an efficient, reliable, and easy-to-apply solution.
