From Dan Boccia:
"Regarding anchors and anchor systems, there's a book I highly recommend called "Happy Hooking - the Art of Anchoring", and S/V Panope on Youtube has done an enormous amount of rigorous real-world, detailed testing on anchors. From both of these resources and my unhappiness with a typical Bruce-style Claw, I went with a Rocna Vulcan and will never, ever, go back to a Bruce-type Claw anchor again. The Vulcan is vastly superior in every way. Regarding anchor rollers, I see little, if any, advantage to long pulpits or rollers - you want just enough to allow the anchor to clear the bow on the way up, and any more is just extraneous IMHO."
