I did use an
anchor bend (aka:
fisherman's bend) on the
anchors, and stitched the bitter end to the standing end with a bit of whipping twine to make sure it'd stay put down there in the water. But on the two throwables I used an
angler's loop (aka:
perfection loop), instead. The throwable for the little stink-boat is just one of those rectangular cushions--there's no actual ring, so an
anchor bend wouldn't have worked well on that. And the ring on Abracadabra's throwable isn't big enough for the knot. The
anger's/perfection loop is a very neat knot. Very secure. In fact: It tends to jam, which suits me just fine

.
As for the rope: The "rope guy" at the WM store (an accomplished sailor, btw) said it was Dacron. Oh yeah: And it doesn't float
