bilge water

after a week on her mooring i had reason to bring her out and whe nthe drain plug was removed a lot of water came out.
is this rain water getting through the inspection covers ?
or is it more sinister. hull seems good.
if its coming through the circular inspection covers then is there a sealant i can wipe over the rubber seals with ?

Catch some of the water and boil off a tablespoon full to see if you're left with salt.

Good indication of where it's coming from.

These circular inspection covers aren't 100%

My boat has always had a lot of water in the hull. I had it on the driveway for a week and with only light mist in the air it still acquired two buckets of water from the moisture.

Before putting it in the water I cut a hole in the lower hull so I could get to the lowest part of the hull just before the drain plug and fitted an automatic bilge pump. It now sits there turning itself on and off every 3 minutes but does the job. My big concern was power usage but it was doing it for over a week and still had plenty of power in it to start the engine etc.

Just double check it doesn't smell of fuel first ;-)

We've had the odd tale of a bilge full of fuel before!

They should be 99.999%. Dinghy sailors use these routinely and they can be upside down for long periods and still come in dry inside. You shouldn't need a sealant...

I'd start with my drain plug - purely based on past experience.

Soapy water and the air pump should find the point of entry for you...

Yep. They should be...but they're not.

I've replaced one twice because it was leaking (a "branded" make) and ended up having to use sealant on it.

They'll keep out rain but if they end up submerged under a pool on the deck they'll leak.

Or stick your finger in & taste it, a much quicker "field test"

It sounds like you have a hole in your boat!

If it's a Rule Auto Computer controlled bilge pump, they cycle every 3 minutes or so "hunting" for water, bloody annoying. I have mine on a manual switch.

There's probably lots of scenarios this would apply to but for most it would be safer to get someone else to do that for you...

Ach! As a diver of many years & working in the "waste water treatment" sector, I've probably ingested much worse than a drop of bilge water When I'm flushing the engine, it's SOP to taste the water from the tell tale (notice I didn't say "pee hole") to see if the salt is gone.
