Electric Hydrofoil - The best electronics for the job?

i wanted reach out community guidance in choosing hardware or micro controller project.  building electric hydrofoil , want use arduino various functions.  can search lift foil or jetfoiler better explanation of i'm trying accomplish.  question hardware/shields should purchase accomplish following goals?

1. bluetooth remote throttle
2. voltage , amperage monitoring of batteries , electric motor
3. motor control , throttling, pwm
4. gps readings (for speed calculations determine greatest distance/amps, i.e. range)
5. hall effect or optical rpm sensing of propeller
6. sonar sensor monitor water depth
7. datalogging analyze above data

the system run on 40-50 volts i'll need voltage regulator.

i'd find arduino/shield facilitate these goals while utilizing minimum number of components.  economical pieces of hardware can purchase require least integration make project work?  there sensors noted above difficult monitor simultaneously (bluetooth , gps example)?  there else i'm not considering?  there specific arduino should use integrate of these needs in 1 board?

thanks in advance.

hi,
welcome forum.

please read first post in forum entitled how use forum.

can tell electronics, programming, arduino, hardware experience?

you had better add rudder control, or direction control if using drive motors , want steer tank or dozer.
