Bilge pump
Bilge pumps on sailing yachts: electric and manual, float switches, and FairHelm survey checks without inventing flood rates.
这是什么
A bilge pump moves water out of the bilge, usually with an electric pump plus float switch and a separate manual pump for redundancy.
Anchor
FairHelm sea trials include a quick pump test when safe. Nordic boats often hide wiring in deep bilges with oil and debris that jam floats.
FairHelm judgment
FairHelm judgment: one silent electric pump with a dead float is not a safety system. Manual pump reach and hose routing matter. Do not trade away pumping capacity for cosmetics.
Limits
We do not invent litres-per-minute needs by LOA. Rule of thumb sizing exists in standards; apply a surveyor and the boat's risk profile.
常见问题
Q: Is one electric pump enough?
A: FairHelm prefers electric plus reachable manual backup.
Q: Should the float switch be tested dry?
A: Lift or wet-test carefully. Sticky floats are common.
Q: Does a high-water alarm replace pumps?
A: No. Alarm warns; pumps move water.
