As a Pro-16 owner of 18months, I am very pleased with the boat.
However I did have the self same problem the first time I recovered the boat to the trailer where the glass had not been pushed down on one of the strakes.
After a BIG moan at the dealers, they collected it the next day and repaired it without question.
Aparently up until late 2004, the hulls were fabricated in the UK, and shipped to France for assembly. Then Zodiac decided to do it themselves and created their own factory which had some 'teething problems'. Perhaps that could be the reason the boats seen were less than perfect.
As to the sniping, every RIb owner I know thinks that the make of boat he/she drives is the best thing since sliced bread, and every other make is beneath contempt. As do Car Drivers, yachties,Bikers,White Van Men .......
