A friend has done extensive anchor testing, if you don't watch any of his other videos, watch this one: https://www.youtube.com/watch?v=l59f-OjWoq0. He picked the Spade as the best design for himself, partly because the roll bar anchors didn't work well on his setup.
I use a 35-lb Delta with 100' of 1/4" HT chain and 300' of 1/2" nylon, the whole setup works well for me. I installed a Lewmar V700 windlass in the anchor locker to make life easier and it has worked just fine. http://members.shaw.ca/ptarmiganshift/images/IMG_0743.jpg. I was carrying a 22-lb Lewmar Claw for backup, then another friend sold me a 33-lb genuine Bruce which is my new backup. The design and construction details are vastly different on the Lewmar claw, the edges are blunt, the curvatures are very different, and the whole anchor is crudely made compared to the Bruce. Steve (the Panope anchor guy) found that knockoff anchors are frequently useless. He couldn't get a Bruce copy to set, same results with a Danforth copy. I almost feel guilty selling the Claw knowing it is not a great anchor. Jim Watts Paradigm Shift C&C 35 Mk III Victoria, BC >
