A Deck Overhang

[Clifton Johnson]

I had never really noticed this until I had read Ken Marschall's Cut Away book and I saw that A Deck stretched out over B Deck. If anyone could tell me how far that it stretched out it would be a great help.

This 'overhang' was a common feature of passenger ships, particularly transatlantic liners.

There was a degree of progressive 'tumble-home' from the 'breadth extreme' on all the decks beneath and this was resolved by throwing out the superstructure, usually at promenade deck level. By definition this structural resolution could equal but not exceed the breadth extreme.

Presumably the ideal was to garner more promenading space. The fact that the prom.deck was also the lifeboat embarkation deck might have had something to do with it.

It occurs to me that the node or knuckle thus formed might on occasions have given problems during boat handling exercises, particularly retrieving a lifeboat against a list.

As to the extent of the overhang in the present case, I can only suggest you measure the width of B Deck on a representative cross-section, scale it up and deduct the half width from (the registered breadth extreme/2). That should give you a fair result.

Soha nem vettem észre ezt egészen addig, amíg el nem olvastam Ken Marschall Cut Away című könyvét, és nem láttam, hogy az A Deck kinyúlt a B Deck fölé. Ha valaki meg tudná mondani, hogy meddig nyúlik, az nagy segítség lenne.

Szia!
