"Do they see us??" The Sun as "frenemy"
Ah, sunny summer, out on the water..
Okay, that powerboat, are they heading towards us? Yeah.
*Do they see us*??
Well, do they? Hmmmmm, it's important. they can manuever quicker than my sailboat, and I'm going to take the worse of it if they don't.
Hint: think Sun--where's the sun? Who's Up-Sun and who's Down-Sun?
So if you're looking downsun at him (easy, scenic, and fun), he's looking upsun at you (difficult, and hard on the eyes--especially low sun that's also shining off the water, making one effectively blind), then no, maybe he doesn't see (oh yeah, and be humble for the vice-versa, maybe you didn't see someone upSun?? Hmmmm??).
There are also sub-groups of reasons why he doesn't see you, especially late afternoon (think blood-alcohol level), or absence of a driver at all (think autopilot), or a driver not even looking at you (think waterskiiers, boogie boarders, fishing lines) But the Sun is probably the biggest reason (being charitable to the drunk and absentee helmspersons here).
So the Sun is your friend, or your enemy. Keep the former close, the latter closer, and (think Hill Street Blues), "HEY!! Be CAREFUL out there"!! ;-)
Oh, PS: at night, background lights are the "night Sun". thats why boats/ships leaving port usually see the (lights of the) ship that hits/barely misses them, while the inbound vessel often doesn't, those nav lights blend into all the others
and PPS: Ask the Coast Guard searchers, whether in surface cutters or airborne, which direction they find people in, and save them: it usually isn't up-Sun. Down Sun rocks..
