Here is one i found on youtube
I like the stingray, nice wide spacious bow for freighting. I always have 150 gallons of fuel on my bow for my adventures so thats why i like it. The one in the video seems to be a 5m, so the 6.5 would be quite roomy. Might plow through larger waves if entering them carelessly due to the Collar being square-nosed and not tipped at the bow. Not a big issue IMO. I have never seen a Tri-hulled rib so my 2 cents on that is very limited. It all depends on your opinion and requirements for that you intend to use it for bro.

They didn't seem to post good specifications on website, Deck Configuration, Hull Deadrise, Tube Diameter etc. Usually you can download the manual in pdf form from what i learned most manufacturers do.
I shot them an email so we will see what happens.
