Of all that BS this is the most accurate pic you have
Uhm, you want to start measuring your d**k .... again?
I don't know why, but anything I post is apparently offensive to you. As I suggested before, remove chip from shoulder.
Whoe said I was adressing you and who says I didn't deliberately choose simple illustrations? I think it very well helps explain the confusion over SWATH, which the Iranian ship is obviously not. Nonetheless you feel the need to restate what was already stated and pretend to be posting something new.
SWATH has a round submerged submarine shaped hall at the bottom
Did I claim or did the image I posted suggest otherwise?
Catamarans come in different forms SWATH is one of the catamaran forms
Was this a point of contention?
The first two pics show HMAS Jervis Bay (AKR 45), a wave piercing catamaran that was operated by the Royal Australian Navy (RAN) for some time (10 June 1999 to 11 May 2001), under a two-year bareboat charter signed in May 1999. Today, She is now owned by Condor Ferries and is named HSC
Condor Rapide, providing English Channel ferry services (St Malo-Channel Islands). This and e.g. the USN's HSV-X1 and HSV-2 are not SWATH ships.
uss independence uses a moderation of the two I suspect
The hull design for the Independence class evolved from an Austal project to design a 40 knot cruise ship. That hull design evolved into a high-speed trimaran ferry called HSC Benchijigua Express. A trimaran is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull. This ferry is the second-longest trimaran in the world, less than a metre shy of the
Independence class littoral combat ship, which was in effect based on
Benchijigua Express's design.
Iran's ship doesn't have a round sub shaped hall it it's wave piercing
A Small Waterplane Area Twin Hull, better known by the acronym SWATH, is a twin-hull ship design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, maximizes a vessel's stability, even in high seas and at high speeds. The bulk of the displacement necessary to keep the ship afloat is located beneath the waves, where it is less affected by wave action.
It clearly is not a SWATH ship as its has hulls and these are not submerged (and do not appear of a design that would lead one to believe that they could submerge, as it the case with some SWATH ships).
This is a SWATH ship (USNS Sea Slice)
And this is how it sits in the water
Given what you've posted on Wiki, you can't use it without damaging your own credibility. A problem I don't have.

Far all we know it can covertly drop advanced Iranian mines (Iran purchased externally advanced mines from china) or Sensors beyond the Persian Gulf without detection....
They can also build a version that can covertly replenish Iranian midget subs, small missile boats...
Fact is they know in advance exactly what they planned to do with it and they are not obligated to share any information with anyone
Of course that should not preclude anyone with half a brain from using that brain to try and figure out what it's intended purpose is....
The twin hull design of a catamaran produces a
very stable platform, which makes it particularly suitable for use in fast ferries or similar roles. Wave piercing catamarans have
excellent exposed water performance. This thing is fitted with a
helicopter deck which aparently is a big deal (considering the demonstration).
