I also canoe at night (which you told me you do too), which not makes
for far fewer motorboats, but also hides the mountains of trash (yes,
including batteries and mattresses) left behind by the said
motorboats. (I have a bright kayak for daylight, and camouflage canoe
with proper lights for night time.)

In all my years of boating and kayaking, I've never, ever seen a battery
floating by. As far as I know, boaters aren't really well known for dumping
their mattresses in the water either.

Perhaps you'd like to explain why you crossposted your complaints about
boaters in the Intracoastal to rec.scuba and a UK group, all of whom are
extremely unlikely to even know what the Intracoastal is, let alone care
about boats in it.
