Thank you for your feed back. As I wrote before, these kinds of contradictionary test results, if one can say that, is still confusing me. Yacht and other magazines praise the Opium and Elan 350 as the future and as very fun and fast boats. At the same time they do not seem that fast and not so willing to plane downwind.
A shallow draft is not a must for us even if the 2,15 on the Opium starts to be close to acceptable.
