needed at the Tx end - just think of the Arduino as a PLC(programmable logic controller) that interfaces between the receiver and relays, servos, speed controllers etc. in your boat. It is good for when you have an array of different items you want to control in the boat - something you might not be able to do with a standard 6 channel TX.
One thing that is useful is that you can control multi- motors without using a conventional mixer - you can programme it to do exactly what you want for steering and drive without using the rudder if needs be. It is extremely flexible for switching lighting on and off, in zones, in sequence - in fact the world is your oyster so to speak.
The Arduino Nano is a compact multi-output device that is very reasonably priced and there is so much free tools and programmes on the web to download and use or modify to suit your own requirements.
If you just want simple control of throttle and steering plus a relay to switch lights then stick to existing conventional equipment.
