Any experience with the Tahe Marine Wind Solo?

This boat has been on my list for a while and i have come across a very good deal on a used fiberglass one. I have not put eyes on it yet but i am looking for any reviews or info i can find but there is not much out there. I plan on mainly using it for fitness and Marathon racing. Is there anything with a design that I should be looking at carefully when I check out this boat? Maybe flaws with older models or whatnot? I have seen that some of the earlier models had some build quality issues possibly but I can’t really find it date to compare this one to to see if it might be prone to this issue.This boat has always look pretty perfect for my purposes except for the fact that the seat looks crazy uncomfortable haha.
