When it comes to drilling holes through your hull you want to make sure it's done right and by experts.
With decades of experience, South Coast Shipyard is the obvious choice.

​It’s important to inspect and exercise your thru hull valves monthly. If you observe leaks, excessive green corrosion or if the shut-off handle is frozen and will not move, the thru hull, doubler mounting block and valve should be replaced. The excessive green corrosion and/or underlying pinkish color of the bronze metal is a likely sign of electrolysis damage that weakens and makes the metal brittle.

Do yourself a favor and don't wait this long. Your safety could be
​at risk.

Properly operating thru hull valves are one of the most important safety features of your vessel. They serve as a safety ​defense in the event of a damaged hose, enabling incoming water to be shut-off immediately. Thru hulls and valves are located anywhere on your vessel at a hose connection, where water is coming in or exiting the hull below the waterline.
