Ok expand on this. What size ship will have AIS ? What size craft is to small for radar ? They say sailboats will not show on radar without enhancement? What kind of collision is the most likely?
I ask with no real experience so you will have to give both sides of the story.
Ok, so it's around 5 PM local time in Indo waters, maybe doing your before dark checks, scanning the horizon, etc, maybe putting in a reef, having a bite to eat, scannng the horizon 360 degrees with the MKII eyeball, AIS, etc, Noting to be seen, great, nice night ahead. About an hour later it's dark...Then...WOW...as far as your eye can see are lights...dim, kinda dim. maybe bright, white, yellow, green, red, blue, flashing occulting, every kind of flicker...what's this? geez, it's a zillion small craft, bobbing in the swell fishing, not a proper nav light in the mix...jeez, talk about a terrorist activity...no rhyme or reason to direction, some boats with no lights, they flick a Bic lighter as you go by...we shine the zillion power light on the sails to increase our visibility...so yeah, not a fun night...and this occured on many nights. Radar helped, AIS was worthless here. MKII eyeball price less!
