Bottom thickness 4 mm?
Which would be the estimated speed?
It would be better to increase to 5mm the bottom?

Max speed is near 44 Knots with a 200 Optimax and a 21" pitch Revolution4 propeller.
The 4mm thickness is enough for me because the hull has many reinforcements. Do you intend 5mm only for the bottom?
ps the transom has 6mm thick

I can send to you ,only for information, the transom design approuved by B.V. of my NAJA 12 ASD, 12m length, 4 x 300hp, + 50 knots.
The bottom t = 5mm
The transom t = 8mm
The transom shield for engine installation = 25mm

Those thickness are good for your 12 m boat, but in my opinion are too much for my 6.75m boat..
Send me your transom designs, thanx, I'm interested.
