Travelling at night or in low light hours is the same as going offshore for the first time, it's all about confidence. As others have said, take it easy, slow down and know the area! Especially trying to navigate bar crossing, headlands etc in the dark can be somewhat dangerous. Have all the safety requirements and please wear a life jacket! It's also a good idea to have a rough knowledge of the conditions expected.
First light, is the best time to catch snapper imo but don't risk yourself trying to get there!
Cheers scratchie!!!
