Which of the following is a potential hazard that should be avoided on small craft?

• A. Keeping wiring dry and insulated.
• B. Exposed wiring near water.
• C. Using weatherproof connectors.
• D. Replacing blown fuses.

Answer: (C)

In small craft, moisture and water exposure at electrical joints create a real danger: water can breach connections, leading to short circuits, corrosion, shocks, or fires. Using weatherproof connectors directly targets that risk by sealing the connection points against water, salt spray, and humidity. When joints stay dry and insulated under marine conditions, the electrical system remains safer and more reliable, even if the surrounding environment is wet or splashing.

Keeping wiring dry and insulated is essential practice, but weatherproof connectors are what actively prevent water from compromising those connections in the first place. Exposed wiring near water is the hazard to avoid because it invites moisture to come into contact with conductors, increasing shock and fault risk. Replacing blown fuses is an important maintenance step, but it doesn’t address the moisture intrusion hazard at connections.
