Jon,
i think its really about time you got off the fence and told us what you REALLY think of the imperfections in Mr Rings hull designs!
Well to be honest, With the larger rings at least, my opinion is almost exactly the opposite of Pc92, ie, Rings are possibly a little quicker for a given hp, than the Phantom, but the Phantom has superior handling/behaviour when it roughs up.
On the bigger Rings, they have a shallower deadrise along the centre line (between the inner spray rails deadrise is under 20 deg) and a slightly rounded keel line, both of these features make for more speed per hp.
However, their very heavy spray rails FWD, which run fairly horizontal and bold, right to the stem, when presented to the sea ( a wave) a little one sided, try to steer the boat by the bow (bow steer) which can induce a lovely hook, the Phantom design has a far more neutral, and thus forgiving FWD spray rail design (IMHO)
When we raced the 26' Ring designed 'Exreme', we had a considerable top speed advantage over Roger Severy's 28 Phantom, but when it roughed up he was in a different class, this wasn't all down to the hull design, but it was a major part.
As I said, all IMHO!
