Comments[edit]

I'm posting this on the talk pages of the related articles, in the hope of unifying them.

I've just discovered the very haphazard nature of articles relating to the various methods of (for want of a completely neutral discriptor) removing a boat or ship from the water. There is lots of crisscrossing going on between dry dock, slipway, patent slip, marine railway, shiplift .... There isn't even a page for the most common name of one method (albeit a brand name), Travelift, or lift ship, as used for the USS Cole.

I suggest the following reorganization:

Each article would have a common set of links to the others.

Also, I think a distinction needs to be made between launching ways that have no means to haul a vessel out, and a true marine railway.

Leonard G's recent edits only highlight the need for clarifying this topic. I believe this article is meant to describe what I would call Lift Dock; a rigid platform that moves up and down off of which ships held in a cradle can be rolled or slid to enable further use of the lift. Lift docks do not use slings. There should be a seperate article on Travelifts. Pjbflynn 18:31, 6 January 2007 (UTC)[reply]


I changed some contributions because it went in the wrong direction. The basic idea of a shiplift is the fact that it uses a steel platform. The picture I deleted is a travellift or a boatlift for smaqll boats. This has nothing to do with a shiplift.A shiplift is fixed in a harbout, you can not drive with it. Most shiplifts in the world have capacities over say 800 tons up to 27000 tons, whereas the boatlifts/travellifts have max capacities of say 500 tons. There are some 4-5 companies over the world that supply shiplifts. Some of them use their tradename for a shiplift, such as Syncrolift (or Synchrolift) Docklift, Hyku lift etc, but these are just shiplifts with a steel platform and a number of winches.Lloyd's register of shipping uses the official name given by them, but not used by anybody else in the world: Mechanical Lift Dock>

"Lift ship" is a word I never heard before. In my opinion a lift ship does not exist.

I forgot to say that a shiplift platform is always lowered and lifted exactly vertical!

How about some OED research as to the origin of "shiplift", "boat lifts" at canals, etc? US English has "boat lifts" presently for simple vertical movement at docks, not translation at canals; this use fits at this article, but with name confusion.165.121.80.250 (talk) 09:14, 10 April 2013 (UTC)[reply]

Move discussion in progress[edit]

There is a move discussion in progress on Talk:Boat lift which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 01:29, 11 April 2013 (UTC)[reply]

Bunch o'stupid at Commons[edit]

Wikimedia Commons want to redefine shiplifts as a sort of port crane: Commons:Commons:Categories_for_discussion/2016/11/Category:Shiplifts#Category:Shiplifts Andy Dingley (talk) 21:06, 19 November 2016 (UTC)[reply]

Andy Dingley stating or implying that people who disagree with you are "stupid" lapses from our policies. I started the discussion that triggered your comment. I do my best not to respond in kind to comments that lapse from our policies. Surely you understand how that kind of comment presents a temptation to respond in kind?
Every question, every disagreement, is a teachable moment. Please consider the possibility that, when you find yourself in disagreement with someone, they may be just as intelligent as you are. Please consider the possibility that, if you marshall articulate substantive policy-based arguments you may win them over to share your interpretation of policy. Or, alternatively, if you give fair consideration to their arguments, they may win you over. This is how we are supposed to try to resolve disagreements, not by name-calling.

Then don't write enormously stupid statements, and then people won't refer to your writings as stupid. Andy Dingley (talk) 00:15, 13 November 2019 (UTC)[reply]
(Do you still think that shiplifts are a form of port crane?) Andy Dingley (talk) 00:15, 13 November 2019 (UTC)[reply]
  • I know that that many people use both "shiplift" and "boatlift" to refer to big marine cranes, without even being aware the term is also used for an an alternative to a canal-lock. It is why I prefer the term we use here in Canada - lift-lock.
  • Andy Dingley, haven't we had pleasant productive dialogues elsewhere? So I would prefer you drop the inflammatory term "stupid".
  • It would probably be best that we use a term like "marine crane" for marine cranes, as boat lift and ship lift will remain unsuitably ambiguous for any use here. Geo Swan (talk) 15:06, 31 December 2019 (UTC)[reply]
  • Why are you even here at this article discussing canal locks? Or cranes?
There is an issue, agreed, where the word "shiplift" has, on rare occasion, been applied to "locks", i.e. level changing devices on canals or rivers. We need to do some sort of disambiguation or clever naming at that article. That article is not this article. This article is about shiplifts. They have no other name. The naming, at least for this article, is clear and accurate.
Nor are they "marine cranes". In either sense of freight ports or construction yards. Andy Dingley (talk) 15:52, 31 December 2019 (UTC)[reply]
  • Andy Dingley, I'm sorry, you are absolutely mistaken. How is it you unaware that "Shiplift" is routinely used to refer to marine cranes, just like "boatlift"? Haven't you ever done a google search on shiplift?
Today the top google hits are, in order:
  1. The en.wiki article: https://en.wikipedia.org/wiki/Shiplift
  2. A youtube to a promotional video that sells marine cranes it calls Shiplifts - https://www.youtube.com/watch?v=5KxFGicUdeI
  3. Official website of a firm that sells marine cranes it calls Shiplifts - https://syncrolift.com/
  4. Official website of another firm that sells marine cranes it calls Shiplifts - https://www.royalhaskoningdhv.com/en-gb/services/a-z-services/shiplifts/769
  5. Official website of yet another firm that sells marine cranes it calls Shiplifts - http://www.penta-ocean.co.jp/english/business/civil/shiplift.html
  6. Official website of yet another firm that sells marine cranes it calls Shiplifts - https://www.gantrex.com/en/industry-21-shipyards/application-61-shiplifts-transfer-yards
  7. Official website of yet another firm that sells marine cranes it calls Shiplifts - https://www.larsentoubro.com/heavy-engineering/products-services/defence-aerospace/naval-engineering-systems/shiplift-transfer-systems/
  8. A website bragging about the installation of a marine crane capable of lifting vessels of up to 4000 tons, called you guessed it a shiplift - https://www.ibinews.com/companies/amicos-4000-tonne-shiplift-to-start-operation-in-october/34705.article
Today one has to go down to the 12th and 21st hits to find links that use shiplift the same way you do.
Yes, I consider this a problem.
Why am I here? Well, for the reasons stated above. Also, you called me stupid, which, obviously, was a lapse from policy, and which I resent. I don't believe in asking for, or demanding, apologies, as I explained in User:Geo Swan/on apologies. I will suggest you consider offering an assurance you will try to use less inflammatory language, in future. Geo Swan (talk) 20:47, 5 January 2020 (UTC)[reply]
