I spotted this video of my 61/65 power cat design Holo Holo powering in Hawaii.  If it’s like when I was there, it is doing 27 knots.   You might need to be on Facebook to see it. Sorry, thats the only place it lives.   https://www.facebook.com/photo.php?v=531218350267143&set=vb.141840345844262&type=2&theater

The government ferry agencies spend hundreds of thousands of dollars on studies about bizzare ways to mitigate wakes on their lumbering metal catamarans.  As noted in my powercat article, a light, slender pair of hulls must be too easy of a solution.
