Then a 36-42mm motor with a Kv around 600 on 10S spinning a 10x6/3 APC Electric prop should get you to 60 mph with reasonable amp draw - assuming the hull design works. The better the motor and cell quality, the better the chance of high performance.
Your hull design is rather unconventional, most riggers have a tub wider than it is tall to lower the CG and to help keep most of the sponsons well above the water at rest. You don’t need the T-tail as it adds complexity and drag, but the vertical may be a good idea. So is the rear shoe, it defines the hull’s aoa.
