Avon 580 taking on water

I have a new Avon adventure 580 (6 months old). If it is left sitting on the water for more than a week the hull starts to fill with water, recently after 3 or 4 weeks it was completely full, effecting the performance dramatically. there is no pump fitted and the only way to drain the hull seems to be to take the boat out of the water. Should I be accepting this a general RIB problem or is it an Avon problem?

I have a friend who bought one at the same time and he has the same issue.

Anyone else?

My Delta is nearly 15 years old and is as dry as a whistle! I would be seeking answers and a resolution under warranty!

Cheers

If you search on here for "Avon Adventure" you'll find they have been the subject of much "discussion" recently, unpopular with a few people!

Best advice would be to get in contact with your dealer or Avon direct, as it's only 6 months old and this absolutely should not happen, there shouldn't be any problem getting it sorted under warranty.

Just double/triple check you haven't left the bung out before you get on the phone shouting the odds

Is it just raining hard ? Any RIB (OK not all - the big ones have decks abover the waterline so can drain) will fill up if not fitted with a pump of some kind.

If its between the deck and the hull then I'd say you have problems - but if its 6 months old give it back to AVON to fix asap.

Roll on the Avon comments.....

Not sure what the avon is like however on our Humber OP the deck drains to a well at the back where there is a float switch/pump.

The inner hull has a bung in the bow anchor locker and a bung at the back to drain in to the aformentioned well.

If we leave both bungs in, the bow anchor locker fills with water over a few weeks of rain and on arrival we have to unplug the bung to let it drain through to the rear well.

So when we leave it on the mooring we leave the bungs open so it drains through to the rear well and is pumped out. I spoke with Humber re this and they said it is perfectly acceptable to leave it like this.

If your inner hull's drain plug is on the exterior of the boat you can't do this obviously and if the design is that the inner hull should be sealed, go back to Avon.

Others will be along in a minute to help confound any of your worries re the adventure. Not the most popular of boats on this forum. However some like them.

When you say "the hull is filling up" I presume you mean the inside of the rigid GRP hull, not the above deck area (my mind's gone blank on the technical terms).

If so - and the transom bung is in & fully done up - then I think it's a warranty issue as others have said. Can you see any obvious crack or damage to the hull / gelcoat?

Any rib without a bilge pump will fill with water if kept uncovered and it rains. If its' the "hull" above the deck, ie between the deck the tubes then a cover / automatic pump I'd suggest would be in order.

It is below deck inside the rigid hull that fills with water. the bung for this is below the water line and was in place and tight. above deck drains fine.

It (the water) could be rain water getting into the holes drilled by the boat builder for cables etc, however these are covered, but when taken out of the water at the weekend it was completely full, 40 gallons at a guess. seems too much for rain through some small sealed holes. which are under the seats and the console and the water was salty so some sea water is getting in somehow .

I will take it up with the dealer/Avon

thank you for the advice

I think it's been mentioned before that you can make the best Rib in the world ony to have a dealer or someone else drill holes in to the deck and screw up the whole operation. I'm not saying this is the case here but it could be.
It may be worth putting it on the trailer and having a good look at the hull and if possible leave it out of the water when it rains to see if it still fills up.
