Matrix 5.5

I have been looking at a matrix 5.5(or so a manufacturer label says) The problem is i can not find a single touch of info on it other than they were made near daytona,fl.

The current owner says he has been using hobie 18 sails and boom on it, and the previous owner installed prindle rudders. For having seen it with my own eyes even if i have to rig parts from other boats to get it on the water $300 bucks boat and trailer is a deal i cant easily pass up. Does anyone have info even if it only on the manufacturer?
To all that may have look at this I have upload pictures to the photo albums
