30.7 knts (57 km/h) for this boat, at 250 hp, it doesn't sound like blazing speed. On the other hand, an 8m long boat that only weighs 2 tons (full load I guess) looks like a huge success, deserving of a big congratulations. Given that the heaviest equipment is what it is and does not depend on the designer, there is no doubt that a commendable job has been done with the structure.
