Talk:Small Waterplane Area Twin Hull

From Wikipedia, the free encyclopedia

[edit] Disambiguation

Swath is also an agricultural term and may describe the "sweeping width" of a remote sensor. Perhaps these articles should be ammended.

Also i would like to point out that the 80% increase in resistance is not always true, yes there is an increased in skin friction resistance, but the SWATH form reduces wave making resistance and due to the increase in the depth of the hull the propeller can experience increased efficiencies, these two increases in efficiencies have also been known to offset the increase in skin friction resistance.

Also SWATHs are not it fact limited to low speed there have been examples of 35 knot SWATHs

[edit] more power, more complex

I don't understand how they use significantly more power. Isn't wavemaking friction dependent on waterplane area (which is lower)? This may be made offset by the greater surface friction, but 80% more power? Really?

I also don't see why they would need a more complex control system than a regular catamaran. Why?--Dj245 (talk) 18:48, 17 February 2008 (UTC)

[edit] Example of an cruise ship

I think there should be an addition about an cruise ship build with this technique. Radison Diamon build by Finnyards (Rauma, Finland) in 1992 at the time, and probably still is the biggest SWATH cruise ship build and operated (Length: 430.4 ft / 131.2 m). I found an page that tells more about it. [1] I don't know should the ship be mentioned in the article, but at least there could be a link added to the page I mentioned.--Gamepad (talk) 19:25, 26 April 2008 (UTC)
