Messed around with it for an hour seems where the hull is touching the beams from the transom 3.5 meters forward the hull is flat but that extra 1 meter up the front of the hull that doesnt touch the hull is bowing
I jacked up the boat from the rear middle of hull and i also jacked it up anout 40% from the back and it was just lifting the whole back of the hull
I am pretty confident its ok the beams are bowing in side ways like the timber is curling how some timber twist as its drying out
If i were to in the future do another hull of this size i would go 190x75mm beams instead of the 190x45mm beams i went with just for extra rigidity
Yet to jump in sode and inspect the hull it was creeking but no breaks while i jacked it up i went easy
Good enough to say shes ready to glass glassing will commence this week if the weather is cool
