I made my mind to get this boat, even if it doesn't have mast nor mainsail (price is really low), so I'd appreciate more of your really valuable help guys. I'm a laser II sailor, and never minded too much about cats until now, so please understand my ignorance. I'm also remotely located, so I havn't many sources of info.

I've seen some used sails, at fair prices, but not the right one. Do you think one from a Prindle 16 or from a Hobie 16 will do, at least for a while? I understand those use boom, so that could be the biggest issue.
About mast dimensions and distance of cable points, I would be very greatful if you could help me.
Thanks so much
Andres
