I sail with my wife and a couple of teen/pre-teens aboard, and the crew are VERY fond of visiting beaches by dinghy... both at our home port, and nearly everywhere we visit (Cape Cod area). I have a 10ish foot RIB, which is perfect for ferrying beachgoers, and often anchor the empty dinghy off the protected beaches we visit, rather than dragging the RIB up on shore. I've been using a 5lb "Navy" anchor (basically a danforth-style anchor without the sharp, pointy parts that like to chafe or puncture inflatables. In sand, and mud this anchor works quite well, and it's very modest size makes is super easy to deploy, and works fine holding an empty dinghy in even a decent breeze. The folding nature of the navy (or any danforth) style anchor means it sits flat on the bottom of the dinghy when aboard the RIB. Basically I love everything about the anchor except that it is 30+ years old, and corrosion is finally starting to get the best of it (galvanized steel). At 30, it doesn't owe me anything. Searching the interwebs, I can only seem to find "painted" small navy anchors... which to me means they will almost immediately scratch, peel, and rust. Anyone know of a small (5-8lbs) anchor that works well in sand, won't corrode too quickly, and preferably isn't pointy/pinchy? Most seem to use either grappling hook styles (probably not as good as flukes in sand) or mushrooms (probably needs to he heavier)... Should I just get a painted one (cast iron) and accept the fact that it'll rust, and stain my RIB.... I kind of hate buying anything for a boat that's nearly guaranteed to get rusty...
