Holes in the watertight bulkhead

Danny,

Have you noticed holes for wires and plumbing in the port and starboard outboard lower corners of the bulkhead going from the forward head and the forward hanging locker to the main cabin?

Hi Gerhard,

you rightly say that there is little we can do about these lost containers because they float so low we cant see them, even if a good watch is being kept. The Amel bulkhead system is our friend. On the SM (which I know best) we have the collision bulkhead which seals off the anchor chain locker. The access port on mine is always closed. Then the gasketed door to the front cabin. We had a report in this last week of a SM being holed forward of this and by closing the door was able to restrict water ingress to the front cabin and make port safely. The water only rose to the level of the berths and the fore /aft trim of the boat was little affected. 

Another example of Henri Amels superb attention to design that matters.

Also the radar don't see them with no area above waterline. Since October 2020 and March 2021 more than 2,500 containers are lost. It is said about 12,000 containers are drifting in the oceans right now. Most of them goes to the ground when lost from the ship but others like reefer containers can float a very long time.

Hi Eric, no I haven't. I have wiring holes at the top outer corners. None at the lower. The only plumbing hole is the grey water bilge pipe passing through and well sealed. However next time I'm aboard I will look but I would be surprised to find such holes since in 12 years I have not seen them.

Kind Regards

Eric,

As far as I know no stock Super Maramus ever had wire and plumbing penetrations through the watertight bulkheads in the places you describe when they left La Rochelle.  

Holes drilled through the watertight bulkheads are by far the most common modification I have seen to Super Maramus that compromise the intent of Amel's design for these boats. It is usually done as part of modifications made by people who do not understand or appreciate the importance of the integrity of these bulkheads to the design of the boat.  Of course holes can be drilled and then sealed, but it is usually easier/better to just use the existing wire chases.

I purchased Kimberlite new at the factory.

On the starboard side under the pullout bunk at the bulkhead there is an open conduit that made it easy to

pull cable through the bulkhead that we used for 110 volts. It is under the carpet.

 

On the port side at the hull level there are some hoses that also go through the bulkhead. I assume it to for hot and cold-water lines.

Eric,

If I understand you correctly, your bulkheads were never actually water tight as delivered by Amel with open conduit going through? That seems... odd?  But boats are odd things...

The water lines do (of course) need to go through the bulkhead to the head sink, and the position of those varies through the production run, but all the ones I have seen were well sealed, and none (of the ones I have seen)  were at the outboard edge near the hull.

I haven't seen a majority of SM's by any means, but I have seen a fair number, and that this be a new one for me...

Live and learn...

I'd love to see pictures.

Our vessel, a 1990 SM#23, has domestic water lines running through the bulkhead where Eric describes (outboard, portside, along the hull, near the waterline). They look original and are glassed in, which means they should be sealed. Makes me wonder what headaches will come when they fail and need replacing. Same story going aft - domestic water lines penetrate the bulkhead to supply the aft head. Air conditioning circulation hose goes back that way as well. But other than that, wire conduits are higher up, basically just below the deck.

Mike,

The wire conduit on the starboard side under the pull-out bunk runs very low along the hull and runs through the bulkhead. It raises up about an inch just aft of the bulkhead making pulling a wire a pain. It is under a flap of carpet and is about 1 inch and a half in diameter. As you mentioned the aft bulkhead has wires running through it in the engine room high on the port side for the AC wiring.

I recall there was a discussion of this on the old Yahoo group a decade or so ago. On SM384 in the forward head, looking in the bottom, aft opening and facing aft, outboard, there is an opening through the watertight bulkhead which, if I remember correctly, is for the A/C seawater pipe, (flowing forward). There is some space around this pipe that water could pass through if not caulked. It may be necessary to remove an access plate to see this. Also if memory serves, I believe the gentleman broker in Fort Lauderdale who has forgotten more about Amels than I'll ever know, may have indicated on that thread that this was the case in a fair number of SM's, and should be checked. But I could be wrong about that part, as the ol' synapses ain't always what they used to be.
