Here's a couple I've done. They are like anything else you just keep doing them and each one gets better. The only sort of trick is it seems to be easiest to do basically the stuff in line with the masts, then work from one end to the other. I prefer to work front to back but back to front seems to be a little more common.
This is my effort at the Black Pearl, hardest part was soldering up 25 1mm square leds for the lanterns inside. I don't have a photo of it lit, I should take one.
This is the Constitution at 1:96 it's the hardest I've rigged. The model itself is over 6,200 parts all wood or metal. I built it in 1994 and re-rigged it in 2015 because I improved my skills to where I couldn't stand looking at the old rats nest.
