I like that your alternator is wired directly to the House buss and through the ACR to the start batt. This separates the charging current from the switch so the switch controls load only.
The only thing I'm having a hard time grasping is the C-1-2 switch. Is C the single common load connection so that house and start and windlass all get power from the battery as selected on the switch? I have 2 switches - one for start and one for house. They can be paralleled at the switches for emergency start. Otherwise, the loads are completely separated between house and start.
