Talk:Bulbous bow

message: I fail to see how Sonar Domes are related to bulbous bows.  Most sonar domes are located on the bottom hull of the ship not on the side surfaces.  Also this section is completely unreferenced. --66.54.184.41 20:26, 29 May 2007 (UTC)
replies: text: Antisubmarine ships routinely use bow-mounted sonar, see  for a good photo of a DDG-51 class destroyer with its bulbous bow sonar.  Georgewilliamherbert 21:06, 29 May 2007 (UTC)

text: I don't think the sonar dome affects to the bow wave since it's located largely below the baseline and not at the surface. As for "weird feeling", I would expect slamming in such case. Tupsumato (talk) 13:03, 11 September 2013 (UTC)

message: :However, neither of these explanations accounts for the fact that vessels with bulbous bows handle better in large seas.
What does "large seas" mean here?  Deep?  High waves?  --Doradus 16:21, Apr 1, 2005 (UTC)
:Heavy seas? Rmhermen 16:25, Apr 1, 2005 (UTC)
::Ok, what is that?  I think we should strive to use minimal jargon, and failing that, we should define our terms.  --Doradus 18:23, Apr 4, 2005 (UTC)
:::When I wrote that I meant "Heavy Seas", which indicates large (i.e. amplitude) waves which are usually (though not by definition) accompanied by high winds and rain/sleet. -Lommer | talk 21:20, 4 Apr 2005 (UTC)
thread_title: "Large seas"?

message: The image caption has been changed from bulbous bow to sonar dome.  If this is true (and it looks like it to me), I think that the image should be removed from the article.  What do other people think? --Apyule 08:19, 10 November 2005 (UTC)
replies: text: I think it still qualifies as a bulbous bow, especially given that the "additional benifits" section of the article explicitly addresses this point. I've clarified the caption to reflect my interpretation... how's that? -Lommer | talk 18:40, 10 November 2005 (UTC)
replies: text: Yeah, looking at it that way I think I've changed my mind.  It should stay now. --Apyule 01:07, 11 November 2005 (UTC)
replies: text: I'm not so sure, bulbous bows are generally only used for hydrodynamic purposes, a sonar dome is a completely different object, it's not really relevant to the topic. I've taken it out for now, and edited the "Additional Benefits" section to make the distinction clearer. Kupos 19:30, 2 March 2006 (UTC)

message: I have read in some books that the effect of bulbous bow on the speed was observed during the American Civil War. Those days ships used to ram each other with pointed iron rods fixed to the bow under water. It was observed that those ships which had these rams traveled faster. And the scientific study followed from that observation.  —Preceding unsigned comment added by 202.1.192.7 (talk) 17:01, 25 January 2008 (UTC)
thread_title:  History of bulbous bow 

message: The phrase "semi-displacement speed range" appears to be jargon. I can figure out the pieces and guess meaning from context, but given its position at the top of the article it should be readable for a well-informed non-expert, yet it is not.  Is there a link that can be provided, or could this be re-worded?  --Scray (talk) 11:39, 25 February 2009 (UTC)

thread_title:  Semi-displacement speed range - jargon in second paragraph of lead 

message: Neither this article nor any other on Wikipedia explain what a "squiggle keel" is, talked about in this article under "How it works":  "...the bulb dampens pitching movements like a squiggle keel." Lriley47 (talk) 01:36, 9 November 2010 (UTC)
thread_title: Squiggle Keel

message: When you look e.g. at the picture of the black and red painted ship with the yellowish bulbous bow in this article you can see markings for the b.b. and the bow thrusters...
Shouldn't there be a mention for this marking/signage in the article?--109.91.42.96 (talk) 23:45, 8 May 2012 (UTC)

thread_title:  External links modified 

message: The lead paragraph includes the following, using a 1936 reference:
:Bulbous bows have been found to be most effective when used on vessels that meet the following conditions:
:*the waterline length is longer than about 
:*the vessel will operate most of the time at or near its maximum speed
The reference would appear to be outdated and is not available on line, so it's difficult to confirm whether it is correctly paraphrased. Barrass suggests other constraints on ship design, as does Bertram. Additionally, there is no modern concept of "maximum speed"; we speak in reference to Froude numbers. It's more correct to say that a bulbous bow is designed according to a vessel's planned operating speed. Cheers, HopsonRoad (talk) 21:23, 17 March 2019 (UTC)

message: The photo in the article does not show the bulbous.  It rather seem to shows slim neck. Did she really bear bulbous bow? Bored boar (talk) 02:31, 4 July 2019 (UTC)
replies: text: The text (and presumably the reference) explains that it is a predecessor design, called a "bulbous forefoot". HopsonRoad (talk) 02:37, 4 July 2019 (UTC)
