Oceanliner Designs explores the design, construction, engineering and operation of history’s greatest vessels– from Titanic to Queen Mary and from the Empress of Ireland to the Lusitania. Join maritime researcher and illustrator Michael Brady as he tells the stories behind some of history's most famous ocean liners and machines!

I like to imagine that waves washing over Mauritania’s bow was so common that her captain started bringing an umbrella everywhere he went just in case.

"We designed this ship to cut through water"
*ship cuts through water*
"Well that was unexpected"

[HamburgerTime]

Another unintended consequence is ship to ship collisions were worse when the prow was not much further forward then the keel, meaning it would almost certainly cut open a ship below there waterline if it rammed it.

Man those knife edge bows looked so good though.

[ptonpc]

The angled bows were also a consequence of ship collisions where it was discovered that straight stems acted like cold chisels on the other ship, causing the damage to go below the water line.
See the sinking of The Empress of Ireland as an example.

All these years of saying "stem to stern" and NOW I find out what the hell a "stem" really is. Thank you.

The straight stem was from a naval design phase where speed was king. its counterintuitive, but the longer the vessel is at the waterline, the faster it can move through the water. due to the standing wave the ship propagates dragging the stern down when it reaches its maximum hull speed. longer hull means longer wave meaning faster ship. The raked bow is the stability compromise. modern ships are impacted by this, but its not as huge a deal these days due to vastly improved engine efficiency and the immense cargo capacity of modern container ships. .

I think the German Kriegsmarine referred to the raked bow as an "Atlantic bow" and even converted at least one battle ship from a straight bow to an "Atlantic bow"

[Coolengineer]

Great Lakes Ships have straight bows. We just do that because we often use that to pivot on when we need to turn the ship around at the dock.

[mrlego]

A lot of cruise ships are starting to bring back straight bows, like the AIDAprima, although they don't look as elegant as they did in the ocean liner days.

This short on bow shape is just the tip of an iceberg of engineering trade offs.

[JKSB]

My favorite bow design is that Victorian/Edwardian era steam ships with its vertical and near vertical stems. Best looking ships ever despite water splashing on the forecastle deck...

[ConvairDart]

As a Mariner, I also like a flared bow that deflects the waves to the sides instead of coming over the top. I did run a fishing vessel built in 1929 with the straight stem. She was fast at 13 knots, but in weather, I had to slow down as the bow would plunge deep and threaten to blow out the windows.

[mbryson]

The battleship _Scharnhorst_ started with a straight stem. Didn't work so well, so she had it altered at significant expense to an "Atlantic bow."

Stem and stern types always seem to be one sort of compromise or another for speed and seakeeping.

Yeeesss, more passionate people nerding out about things they know about! This is my favorite type of content. Thank you for opening us up to your world!

[samthemultimediaman]

I like how battleship texas kind of uses a combination of a straight stem with flaring on the top and a bulbous section under the water line.

[karlboekdrukker]

I honestly could listen to this guy all day long. His voice is really soothing

[Train]

Later ships, often warships by my knowledge, even had flared prows to stop water from going over the deck.

[Deitrem]

I always thought it was a matter of difficulty manufacturing the angled bow.

[ryanrasmussen]

This is the channel we needed! Thank you so much for your work.

[Ryan-ijge]

And now the phrase stem to stern makes sense! Thank you!
