Thank you Eric and Paulo for the extended information.
The low speed while motoring for the opium (and Pogo?) is not a problem in itself for me since I do not like motoring either and prefer to wait for the right wind. It is little bit strange though, if it would be because of big wetted area at low speed the boats should be slow in light winds and it seems that the opium is not.
A little bit disturbing is that the Yacht test was conducted in so light wind. Doing 9 knots in 8-11 knots of wind is of course nice but it seems like that is also the limit, and that not that much more happens in 15-20 knots of wind, as in the french test. As I said before my main dissapointment with traditional performance/cruiser designs is that they do not take off and give a thrilling ride in 18-25 knots wind speed (without a crew and a spinnaker) and it seems that only a light Pogo 12.50 does that.
