Taking on Water: What to Do on a Rental Boat
A real hull breach is rare on a well-maintained rental boat, but knowing how to react in the first seconds changes everything. The checklist to know before you leave the dock.
Taking on water is a rare event on a properly maintained rental boat — but it's exactly because it's unexpected that it catches people off guard. Knowing what to do in the very first seconds, before you even have time to think, makes all the difference.
Why the first reaction matters most
Faced with a sudden emergency, the human brain doesn't switch instantly into action mode. British researcher John Leach, in a study published in 2004 in Aviation, Space, and Environmental Medicine (see the study on Google Scholar), found that a large share of victims of maritime and aviation accidents first freeze for several seconds, sometimes minutes, before reacting — a shutdown response rather than panic. Knowing the steps in advance noticeably shortens that delay.
The steps, in order
- Find the source: a through-hull fitting, stern gland, seacock or hatch seal — often visible or audible from the bilge.
- Get life jackets on the whole crew, no debate.
- Start the bilge pump, manual or electric, and plug what you can with whatever is on hand (a rag, a cushion, a wooden wedge).
- Call on VHF channel 16, giving your position — our guide to VHF and safety at sea explains how to phrase the call.
Head toward land, not away from it
Unless rescue services say otherwise, head for the nearest harbour or beach rather than staying put: a boat taking on water is often still manoeuvrable for a while, and every minute counts. If the situation is beyond you, our guide to towing and assistance at sea explains who responds and what it costs.
Two minutes before you leave
At the departure briefing, ask where the bilge pump is (manual and electric), how to activate it, and where the through-hull fittings are. This check takes two minutes and costs nothing — it's part of what our guide to the pre-departure technical briefing covers. On a recent, well-maintained boat the odds of a real hull breach stay very low; that's exactly why it's easy to forget, and why it's worth preparing for calmly, before you cast off.
