TOPIC: Tri-hull identification

Hello all,
This will be my first post, but thank you for having me. I purchased a trihull boat last year and am thinking about doing some extensive modifications to it. I would however like to know what manufacturer or model this boat was originally. I have been unable to find an ID tag and the registration was listed as a homemade boat.
Had a gentleman stop me at a gas station once though and told me it was a Johnsen skiff, but from what I can find about them this is not that.
In the long run its not too big a deal I suppose but still curious about it.
Thanks in advance!
