I was on a water taxi returning from Caye Caulker well after dark and in the rain a few weeks ago. I had a handheld GPS unit with me and I checked our speed - 33mph. That was slow - I've clocked 40mph on other occasions. I know from personal experience running a dive center that in these conditions other boats can be very hard to see, and I'm sure we were as well. If you're on a boat travelling at that speed, in the dark and the rain, then even if your boat is well illuminated so that others can see it, they can't judge your speed and direction precisely enough, and you probably can't see them.

I don't see how these speeds in these circumstances can possibly be safe.
