What material can be used to make temporary repairs on a vessel taking on water?

• A. Caulk
• B. Epoxy
• C. Duct Tape
• D. Plaster

Answer: (A)

When a vessel is taking on water, the first goal is to slow or stop the inflow quickly so you can reach safe conditions. The material used for a temporary repair should seal leaks fast, stay flexible with movement, and be easy to apply under pressure. Caulk fits that need. It’s a pliable sealant designed to fill and seal gaps and seams, so you can apply it directly over a leak or along joints to form an immediate barrier. It remains flexible in water and under motion, which helps it hold a temporary seal long enough to reach shore or complete a more permanent repair. Epoxy can be effective for stronger, longer-lasting patches, but it often requires mixing, proper surface prep, and curing time—not ideal for a quick, onboard fix. Duct tape and plaster aren’t reliable for hull leaks: tape tends to peel in water and movement, and plaster isn’t suitable for sealing bare hull surfaces.
