You need a threaded connection on your hull and the barb keeps working loose. This Jaycar skin fitting gives you a proper mechanical lock on your 1/2-inch BSP port. 36mm internal diameter. Whether you're drawing water in or discharging from the bilge, you get one clean, sealed connection instead of a drip that gets worse every outing. Cut the barb off, thread it on, tighten. Problem gone
