Step-by-step instructions
Confirm the timing
Note whether water appears with rain, sailing heel or engine operation.
Rule out serious leaks
Check that no below-waterline or plumbing source is active before assuming rainwater.
Track the first wet spot
Dry accessible areas and inspect around chainplates, ports, hatches, deck fittings and hose routes.
Inspect drains
Check blocked cockpit scuppers or deck drains that may route water unexpectedly.
Repair the source
Remove and re-bed hardware only when the correct fastening, core protection and sealant method is understood.
Safety note
If bilge water rises or the source is uncertain, treat it as possible flooding and seek urgent help.
Key takeaway
Water can travel far from the leak before appearing in the bilge.
