Hi, do not worry about your English, it has to be better than my French!
Scubacat is 8m, no 20.
I have the old Catalac records at home and will update them when we get back, ,but at the moment we are sailing on south Coast of UK, heading west as the weather allows.
If you have any Catalac or sailing question, the best thing is to ask a question in the forum, then all members have the opportunity to help with answers.
