Beneteau Antares 30 fly Concerning water in lazarette

As you now have your question on two posts may I suggest any more replies relating to the Antares 760 be posted to the other one.
 
Hi
i have recently purchased an Antares 30 and have since noticed water appearing in the bilge below the forward double berth.
It only seems to reappear after a trip. I have had an engineer check the sea water pump and bow thruster but nothing.
The water appears to weep from a small drain hole in the front stringer.
Any advice/help would be much appreciated.

Salt water or fresh?

I have an Antares 760 but there may be similarlies with your 30. I was getting saltwater collecting right forward, only after a trip out, not at rest, and it turned out to be the rudder stock! The seal at the top of the rudder stock is above static water level so no leak at rest. Under way in a seaway some water can get forced up the rudder stock tube and if the seal is worn some will enter the boat and while under way will stay aft. Once you slow right down the water finds it's way forward between the hull and the inner moulding until if finds the lowest point right forward.

Thank you. It’s not easy to see the top of the rudder. I have removed the manual steering cover but can’t really see anything unusual. The fuel tank prevents easy access. Was yours accessible?

Hi All

I am becoming a little concerned as to a small (3+ lts) sea water apparent in the lazarette after an hour or so of cruising around. The boat has a double skin hull and there are two drain holes (see pic) which holds quite a lot of residual water. I have on occasion pumped out 8 ltrs of sea water from here but cant see just where its been shipped. I have checked all the valves and sea cocks etc and whilst there is a build up of salt crystals in the bilge there is no apparent water under the shaft seal. Also checked whilst the engine is running in gear and see no drips etc and there was nothing. As this is a double hull skin I cant see where this water might get in. Any suggestions will be gratefully received.

I’m familiar with a slightly bigger Antares and I think this will apply. If you have a stern thruster you need to take measures to keep that dry until you solve the problem. Rig a temp pump aft going into a bucket so you can monitor volumes would be a good idea. If the motor gets wet it’s toast. Expensive toast.

Yes, I had good access. How frustrating for you. If you can live with the small leak while under way and there is no water ingress at rest it may be simpler to live with it???

I had the keel band fall off my Antares760 without me realising and the half dozen self tapping screw holes proceeded to leak a lot of water in till I could confirm what was happening. Drove me mad for several weeks and I was baling buckets out morning and night (seawater came in at rest and underway). Had to lift out before I could see it all dripping out like a shower head and get it all glassed over properly. You might have something similar starting where water is being forced in past a fitting by pressure underway but not at rest?
Strange you can't locate the source of the leak when underway.
It might show itself when lifted out the water on blocks if you add some fresh water into the double skin with a hose?

Agree might be a good idea to automate a bilge pump and fit an alarm as it might increase to a more troublesome amount at some point before you find out where it's coming in. Assume you have an elec pump in the bilge already that could be made more effective?
I got mine upgraded to an automatic pump with an alarm after my experience above so it will pump out when I'm not there.

Good luck finding the source, its quite stressful seeing water on the inside.
 
No experience with Antares 30, but I had a similar issue with my Antares 8. Water weeping from somewhere ending up in the stringers, obviously making it very difficult to locate root cause. Only reappearing during and after a trip. Turned out to be a faulty lip seal in the sea water pump (position 6 in this drawing: http://www.depcopump.com/datasheets/johnson/10-24515-01.pdf) causing the bearing on the sea water side to corrode. The salt water found its way quite unnoticeable via the bow port side engine mount to the port stringer... In order to finally establish this being the root cause, I've replaced the shaft seal, through-hulls, etc. At least now I know that those items won't need replacement for a while. Rebuilding the sea water pump was fairly straightforward, and kits are available online. Being in Sweden, I had to order the kit from the US but hey – beats paying for a brand new pump.

Apologies for resurrecting a three year old thread, but was there a resolution to your problem @Popski?

I am experiencing the exact same issue, but with an Antares 8. Takes in water when underway but not when in berth. All through hull fittings and valves have been checked and shaft seal replaced. Salt water seems to seep from one of the port stringers but given the double hull construction, the water may very well be coming from elsewhere. The majority of the water makes it to the bilge where it is pumped out when underway. The remaining water is about 10 litres that I manually have to pump out using a wet vacuum cleaner.

Is your Antares 8, an outboard engine, and even then you are still getting water into the bilge? I ask because i'm buying one and i noticed sign of water in the bilge?
