Hi. I had a CQR on my last boat and it would not set well. I bought a Spade 100 and it was really great. It was oversize for my previous boat but I knew I would be changing to a bigger boat. I bought a Santorin two years ago. It had a CQR with 8mm chain. I swapped to 100m of 10 mm as I though 8 was a bit light for the weight of boat and changed the gypsy too. Shortly after the Spade anchor shaft bent slightly (the shaft is hollow to make it lighter). I have kept the Spade as it is a good anchor, but have replaced it with a Rocna 25. It has performed really well. It is plenty big enough for the Santorin. I have had to file away a couple of centimetres of the fibreglass on the top of the bow roller to accommodate the top of the shaft. It fits perfectly. It does not self launch easily like the Spade did, so I do have to release a bit of chain and give a push with my foot to let it sit at an angle on the roller if I want to operate it from the cockpit.
I also have a Fortress FX 23 as a bower and that works very well.
The Spade and Rocna are both brilliant anchors. The slight bending of the shaft inclines me to recommend the Rocna.
