Remove 'underlink' flag

If people don't mind I'm going to remove the 'underlink' flag as I believe I've remedied the problem. Some editor with better access to authoritative references might also consider expanding the article since there seems to be a lot of discussion of the subject on various ship-design forums, but not much that seems reliable enough to cite.Atani (talk) 17:02, 19 March 2015 (UTC)[reply]

"lifting the stern"

Is this quite correct? As the stern of Lurssen designs was shallower than the rounded bows of the hulls, this "lifting the stern" seems to suggest that the stern would be much nearer to the surface - nearer to being clear of the water - and thus bringing the screws closer to the surface likewise.

Wouldn't this induce more drag from the now-deeper bow section, whilst increasing the likelihood of cavitation from the screws (which would result in a severe loss of efficiency in transference of engine power to the water)?

Perhaps I'm misunderstanding it, but I was under the distinct impression that the stern was dragged a little lower in the water, resulting in the bow being lifted - thus getting the (nose-up' ride attitude we see in photographs and film of S-boats in action. It's hard to reconcile both bow and stern being lifted at speed without the use of hydrofoils. 2A00:23C3:3103:9701:256A:62DD:F1B2:9FE3 (talk) 18:46, 25 September 2023 (UTC)[reply]

The linked article (on Model Warships dot com) describing the effect is not a valid source - it is written by a model-maker based on their bad reading (or misreading) of the effect. (It even contradicts the box art above, which shows the subject of the build in a high-speed posture, with its forefoot running clear of the water - as opposed to the "the stern comes up, the bow goes down"). In short, it is not a reliable, peer-reviewed source and this article should not be relying on it. 2A00:23C3:3103:9701:8870:E71B:6BA7:3848 (talk) 04:24, 27 September 2023 (UTC)[reply]
