Modern Ship design

[Ivan Cloherty]

The swedes had passenger ships with funnels aft in the 40's/50's. Also had cargo ships with no funnels, just exhaust pipes going up the mainmast.

Cargo ships with all aft were very uncomfortable, you certainly covered some gyratory distance on the bridge in bad weather, apart from cargo advantages, in port they kept the stevedores out of the accommodation, as there was normally a Stevedores Office, right adjacent to the gangway. There were disadvantages from a berthing aspect, especially in ballast in high winds the Accomm block acting like a huge sail and pushing you where you didn't want to go, but at times could asist you. However I preferred them to midship accomm. But on midship accomm you never noticed the vessel shaking herself as much as that long foredeck that worked and pounded in a heavy sea and shook herself like a wet dock.

Must admit I have never seen a ship of any size with an exhaust pipe up the main mast. It would mean a very small exhaust gas boiler /heat recovery unit.

Well Lewis, I wouldn't know about that, but guess the guys who built them had it all worked out, remember passing one at sea, very strange to see a normal ship without a funnel, but it sure peaks your interest

Talking of funnels this ship had a strange pair

I must say I never knew she had a big mishap mid Atlantic.

In April of 1966, the Michelangelo was bound from Genoa for New York, when a huge freak wave crashed over her bow in mid ocean. The force of impact caused the forward superstructure just below the bridge to crumple like so much wet cardboard. A large part of the aluminium bulkhead was simply slammed backwards. Two passengers were swept out to sea, and another crewman died later. More than fifty passengers were injured to varying degrees during the accident.

The Canberra, Southern cross and Northern Star were the most recognised with funnels aft.

But take a look at the cruise ships of one company, they have what look like wings on the funnel.

well i suppose in heavy seas they could just fire them up and fly above the waves .....cappy

#16 Well they would increase the temperature in the deck chairs on the Prom Deck aft!

[Lewis McColl]

#16, Your photo made me curious about the pods on the Island Princess . It would appear they are air intakes for gas turbine electrical generators inside the funnel. Some links suggest they are for in port use only as they produce less exhaust emissions therefore are a greener option?

The Island Princess, one of the smaller ones of the fleet.

But Princess now have a couple that are partially gas powered with a couple top come that will run on gas only.
