People are concerned about lack of ultimate stability, which has to be the case with a light centre-board. The yard quoted me an AVS of 115deg for the Ovni 435 (probably bottom end of acceptability).
They don't admit to having the curve, and referred me to the designer (I couldn't be bothered, as I should not have chosen such a design if I wanted a 140+deg AVS). My main concern was a basically strong boat capable of withstanding being beaten up by three small boys, and possibly the odd floating nasty.
I am not prepared to go into long discussions about stability - I am not a naval architect and do not know enough about this subject to be able to make an informed comment. Generally OVNIs have a good record (I don't know of any that have capsized), and as I said in reply to a similar question, I took my boat to the Antarctic and back and wasn't too worried...so draw your own conclusions.
