I was about to write something similar. I found funny that no one seems to have noticed what he wrote!What a load of tripe - a cat with lead in the keels! On top of that you claim to have sailed on one? If you did, it obviously was not in a capacity of any responsibility.
What unbelievable nonsense to write.
Even a pea brained idiot knows that cats do not have ballasted keels. Keels yes, ballasted keels no. Anyone with real knowledge, you do not even need to have put a foot on board a boat to know about this, shall be aware of why some boats have ballasted keels whilst other just have keels.
If you dont know, then rather keep quiet then post incorrect speculation whilst pretending to have knowledge. Yours is a dangerously incorrect posting.
