Something about a hole in the hull?

So sad to see this.  A sober warning to us all to be prepared for any eventuality.

Hi, 
unfortunately I know what happened as I was the owner of this once beautiful boat.
We were 12 miles out of Catania on passage from Toarmina to Siracusa while motor sailing and I noticed a little water , the bilge pump came on and I switched on my extra pump. But instead of reducing the water more was coming in from somewhere. I locked all the cocks but the water continued rising. 
I called for help, launched the dingy and than the life raft but by the time the Italian coast guard who were very helpful arrived an hour later, me, my wife and our dog we watched our boat go under and we were helped on to the coast guard boat.
After trying to think where was the water coming from, the only thing I did not inspect was the compartment behind the aft cabins. The exhaust pipe must have come off the hull fitting and it started putting the cooling water in the boat.
After getting over the shock of seeing the  boat go under, I still believe in Hanse an now we have a 415 and still sailing.

John

Many thanks for sharing such an unusual and useful lesson from a tragic event. Of course, its one thing to sit comfortably in a chair pondering the cause and quite another to be the poor bloke having to deal with rapid flooding miles out at sea but I'm curious that the rate of ingress overcame both the bilge and a secondary pump.

I certainly don't think I'd have considered the exhaust line-up as a culprit either but will now do another crawl-through to make sure everything's tight! You're right in that the aft void-space often doesn't get the attention it might require.       

Very glad to read that you're all back out on the water again.

Thank you John for telling us the story. What a dreadful shock. Iíll be sure to check those hose connections. Last year I had to reconnect the connection to the Vetus water lock which I had inadvertently disturbed when changing the exhaust mixer bend. Fortunately, I found the leak while testing before relaunching.

Agreed. Thanks so much for sharing this story. 

This area is not an area of the boat I inspect with any frequency. 

Will do so next time Iím aboard.

On delivery I found the rubber exhaust hose was not strapped along its length with the result that it vibrated and chafed against the hull.  It made a thumping noise which I investigated and found lots of rubber particles even after a few days..  I am sure this would chafe through in time.  I strapped the hose to restrict movement and it's been ok since then.

Hi,
The reason why my 1 inch bilge pump and the second 1 inch extra pump were not sufficient to keep up with the water coming in must be that the exhaust skin fitting is about 2 inches which is far more than the pumps were pumping out.
Prior to discovering the water coming in we were healing on to the port side for quite some time, so it was not only the engine cooling water that I had to cope with.

Interesting an timely posting. I spent this last weekend working on my Hanse. I arrived late Friday evening. The first thing I did was start the heat pump as it was 3 degrees Celsius. I then when about my first task of pumping out the diesel from my tank so I could clean the tank. When I stepped down onto the floor after an hour in the aft cabin I found 2 inches of water and floating floor boards. Luckily I was still in the marina and they sent over the pump out boat to eliminate the water. We then proceeded to check all the through hulls which seemed all intact. I then opened the heat pump bin and discovered one of the 1/2 inch hoses had slipped off and water was being pump into the boat full blast. We subsequently turned off the heat pump and the water stopped. Here are my observations:
   1. Even though I had 2 clamps on the hose, it came off the heat pump inlet.
   2. The heat pump outlet hose was also almost off.
   3. My concern is why did both inlet and outlet clamped pipes fail.
   4. I was going to start the heat pump and go to dinner while the boat heated up. Glad I waited.
   5. My Hanse Installed sump pump was no where near capable of pumping out that amount of water.
   6. I need to consider a secondary pump to backup the low capacity Hanse supplied pump.
   7. Checking ALL clamped fitting is now on my maintenance list.
