Here are photos that show Austal's JHSV, published in Marine Log. It notes:
The JHSV will have a 103 m catamaran hull (which is actually shorter than the 113 m Hawaii SuperFerry cats built by the yard) and a speed of more than 35 knots. A draft of 3.8 m will allow superior access to "austere" ports.
The second Superferry had these types of ramps installed.
