Talk:Jetboat

message: "Jet boats are highly maneuverable and can often be reversed and brought to a stop within its own length from full speed in a maneuver known as a Hamilton turn."
I assume that "reversed" means not that the jet is reversed or the boat, but that the boat is rotated 180°, bring it to a stop or reversing the direction it was traveling in. -- Soupisgoodfood 13:25, 5 February 2006 (UTC)
thread_title: Reversed?

message: This article lacks any real true details on the marine jet.  I suspect this article has been written by a person who does not know much about jet boats, or perhaps own a propeller driven boat.

replies: text: I've just been bold and remove the entire manufacturers section. Only one linked to a Wikipedia article, so the section was just External links in disguise. If there is consensus that some coverage is needed, I would suggest creating List of marine jet manufacturers - with full referencing required for inclusion. dramatic (talk) 05:02, 30 March 2008 (UTC)

text: And I see no references for anything in the list. (The manufacturers' own websites are not valid for establishing their notability as a manufacturer). dramatic (talk) 10:42, 30 March 2008 (UTC)
thread_title:  External links 

message: The drawbacks section contains the following text: "In my experience, a jet boat will normally use about half the fuel that a boat of the same size does which is propelled by an outboard motor at the same speed." Does anybody know of a source that can be cited instead of this original research?173.48.160.10 (talk) 03:48, 1 April 2011 (UTC)

message: The article briefly acknowledges the "Hanley Hydrojet".  There is, however, regrettably no further Wiki citation. 
The "Hydrojet" was patented by (James) Keenan Hanley, who commercialised various related successful innovations, starting from about 1930 well into the late -1950s. His first patented jet boat was the "Edward T Rose" fireboat design #2,276,193. Hanley Engineering Services in Prospect, Marion County, Ohio used a 30-foot steel hull designed by Sparkman & Stevens [sic - Stephens ?], with four centrifugal pumps each driven by a Chrysler engine, to propel as well as impel water through its fire-fighting monitors. During 1942-43, Hanley's delivered 103 such craft to the US Coast Guard.  These were used succesfully in shallow water. 
In 1948 a slightly larger Fire Float was constructed in Ohio (and then shipped from New York, to the Fremantle Harbour Trust) for use at the main Port of Western Australia, close to the State's capital Perth. 
All of the preceeding summary facts are derived from the book "Without a Prop" by David S. Yetman, Dog Ear Publishing 2010,  .  The book extensively discusses the modern progression from Keenan Hanley Hydrojet designs; most particularly those from the mid-1950s, in Bill (later Sir William) Hamilton's use of axial turbines for his internationally-succesful New Zealand jet boat developments. 
From my personal late-1950s knowledge, the Fremantle Fire Float was only propelled rather slowly up the Harbour by its Hydrojets.  Moreover, its on-station manoeuvrability became limited once the harbour sea-water was diverted primarily into its fire-fighting monitors.  The WA Museum records that this Hanley Fire Float remained in service on Fremantle Harbour until about 1961. 180.200.140.215 (talk) 08:18, 25 January 2014 (UTC)
