The Captain's Take
After years of battling clogged and leaky scuppers, I switched to Perko's adjustable model. The ability to customize the fit to my boat's specific hull thickness makes all the difference. Installation was a breeze, and the peace of mind knowing my deck will stay dry, even in rough seas, is invaluable. Perko's quality is second to none.
