The bilge is one of those parts of a boat most owners check without really looking. A quick glance, a bit of water, seems normal, move on. But the bilge is often the first place a developing problem shows itself — long before it becomes something serious.
A bilge pump's job sounds simple: remove water. What's less obvious is how it knows to turn on. A float switch sits in the bilge and rises with the water level, triggering the pump once it reaches a certain point. If that switch sticks, gets tangled in debris, or corrodes over time, the pump won't activate — no matter how much water builds up.
Worth checking every so often is whether the water in the bilge has any oil sheen to it. That's usually a sign of a small fuel or oil leak somewhere in the system — not an emergency on its own, but something to track down before it becomes one.
A five-minute check before heading out — lifting the hatch, testing the pump manually, glancing at the water — is a small habit that catches problems early. It's not glamorous work, but it's some of the most useful time you'll spend on the boat.
The problem: that five minutes only happens when you're standing on the boat
Here's the catch. That five-minute check is genuinely useful — but it only protects you when you're physically there to do it. A stuck float switch doesn't wait for a convenient moment. It can fail while you're at work, asleep, or three states away, and the first sign of trouble is often a flooded bilge, a dead battery from the pump running non-stop, or worse.
This is exactly the gap Yacht Pilot is built to close. Instead of relying on a manual check you can only do in person, a YachtPilot sensor watches your bilge continuously — day or night, whether you're on board or not — and sends you a real-time alert the moment something's off. Rising water level, a pump that's running longer than it should, a float switch that isn't triggering — you'll know immediately, not next time you happen to lift the hatch or your boat is already below the waterline.
It's the same habit you already know matters. YachtPilot just makes sure it's happening every five minutes, not just the one time you remember to check.
