Tom’s Tips About Through Hulls

By Tom Neale, 2/8/2007

1. Don’t do this at home, or anywhere else.

2. It helps to hire a diver (or do it yourself if you can safely do so) to occasionally inspect your through hulls from the outside. Sea creatures such as barnacles and mussels and clams can grow in there more quickly than you think.

3. Check regularly to see that the bonding wires to your through hulls have good contact and are corrosion free. Corrosion can occur here quickly.

4. If you ever get hit by lightning, consider through hulls and their valves to be prime suspects for damage. It may not be readily apparent, but it could sink your boat.

5. Follow the manufacturer’s instructions as to regular maintenance. It’s hard to remember to do because they’re usually out of sight and out of mind, but it’s important.
