I have Hokua9.0 and paddled the Starby9.0 carbon. The Starboard is way more stable, more floaty and is easier to paddle, mostly due the slightly wider and more volminious nose. When its clean both are fine for my 87-90 kg (depending on the time of the year), but when choppy the Starby is way easier to balance and start (I tend to burry the nose of my Hokua sometimes).
Ridingwise: the Starboard is imo more allround making fun in anything from kneehigh up to 2.5m (biggest I tried it in). The Hokua needss a faster wave and more push. but waves become scary high before the Hokua can,t handle them, it feels like on rails and has heaps of grip, more as the Starby.
In feel and float you need imo compare the Hokua 9.0 with the Starby 8.5 pro. That combo is closer to eachother as the 9.0,s
I really really like my Hokua in clean waves, but overall I think the Starboard and the Fanatic8.10pro are just slightly better boards offering both more stability and a easier start without performance loss until you get freaking high and scary waves.The only place where I really prefered the Hokua over the Starboard was at Maui in front of Mama,s fish house (just next to Lanes and Hookipa) in big barreling waves that where a bit too much for me. As a euro i,m not that used to sucking Pacific powerwaves. In those conditions the Hokua offers a lot of control and straight line speed where the Starboard became for ME a bit nervous.The guy I swapped boards with was a way better surfer and was ripping on both.
