Zaneo,
I've owned sailed and built Paper Tigers. I even have a Paper Tiger mould if anyone wants to make use of it.
The min weight on the platform is very light and the original glass Tigers (egg shell construction) would come in around 10kg over miniumum . ie 60kg instead of 50kg. These may be a little more robust but still probably not up to what you need.
Paper Tigers are fantastic boats but in your case I'd be looking for a Hobie 14, Maricat 14 or Windrush 14. I think the Hobie14 would be the lowest on my list and Windrush the highest.
I agree with Darryl on the Hobie 16.
Once you've spent a couple of seasons on the 14 if you want something more then maybe look at a 16 but make sure you have someone who will come out to help you right it.
Remember there will be times when you are sailing this by yourself without a support craft. You have to be able to right the boat unless you want to become a statistic.

Regards,
Phill
