We have owned a Fleming 55 and 65. We basically live on our 65. The 65 any day is better mainly due to space but also the extra displacement makes a huge difference to performance at sea. If you have instagram check @Freja_f65
Ultra Anchor for sure. We have a Fleming 65 and the 60kg Ultra has always let me sleep comfortably without concern. Once it's set and grabbed it is bulltetproof.
