Voltage Regulator PCB design review

[bulletbolt]

Hi all,

Here I have a project for voltage regulator. This is designed to use in small boats where you would need 12v dc power supply for ancillaries.

It's not a perfect design and sometimes I get various faults, some of them are mystique. If someone, who has more experience with voltage control, could have a look and tell their opinion would be highly appreciated. This is not something I do o n daily basis so need experts advice
 

The questions I have raised is:
What's the limiting AC input
What's the maximum DC load

All this PCB being fitted into small rectangular alu tube and fully potted.

Ideas and thoughts please

It's not really a regulator, it's just a rectifier that skips cycles when the output voltage is higher than the setpoint. It's doesn't seem to include any overload protection so maintaining the current within safety limits is up to the power source.
