A 1976 Valiant 40, Brick House, Osprey, RVing and Tiny Home!, underwent a four-month performance evaluation of Coppercoat antifouling and PropSpeed after a transit from Richards Bay to Hout Bay, South Africa.0:18 The vessel sat in a nutrient-rich estuary for two months before completing an 800-mile passage.0:30 Underwater inspection revealed that while the Coppercoat hull required minimal cleaning—wiping away loose slime by hand—the finish was slightly compromised by the use of 80-grit sandpaper during initial application, which created a texture that trapped sediment.6:11 PropSpeed remained effective on the Kiwi prop blades and shaft, though the owner opted to apply Coppercoat to the bronze strut due to previous adhesion failures.9:19 Proper surface preparation, including the use of manufacturer-supplied alcohol wipes and avoiding contamination, proved critical for PropSpeed longevity.10:10 The combination of Coppercoat and PropSpeed significantly reduced hull cleaning time from two hours to approximately 20 minutes compared to traditional antifouling paints.13:18
