To be fair to the WWPotter guys, I think the reservations about overnighting might be mine alone?
I think the WWP set up is probably safe overnight, but I've not tried it; because I've never yet overnighted on my own anchor!
At worst, my main anchor rode remains attached to the boat, by being made off on the halyard winch. The bow line, "snugs up" the anchor rode to the bow eye. Should there be a carabineer problem, or similar(spring failure, or sharp joint in the carabineer?)? I think I have addressed this by using a very large stainless shackle (shed- "spares") in place of carabineer.
I think the anchor rode rigged this way may well be better protected from the bob stay wire, than it would be with the new "sprit launcher" arrangements?
I won't be seeking to convert to this very ingenious new launcher because:
1. I prefer chain on the bottom at the anchor, can be rocky hereabouts. I have > 8m on both my main, and kedge. Also reduces swinging room (more so than a leaded warp, i would suggest?), as it is often very busy here during peak holidays. This year it's been more like the Solent than Cornwall; a very unwelcome development. Hence we've been anchoring more in isolated gullies, in close proximity to rocks!
2. Too much weight, too high up, too far forward for my liking,
3. High cost. In my case, new anchor, swivel, leaded warp, bracket, clutch, cleat. I do have the necessary plank sprit.
4. My assymetric spinni gybing skills are not good enough to have a large sharp pointy thing dangling off my sprit.
