Thank you, Riyad. It's early days, but the Rocna sets very easily. The extra weight is very reassuring, of course.
The balance of the anchor means it self-launches, something the Delta did not do - it needed a helping hand, so this is a help when single-handed. On the other hand, as the Bav has an almost vertical bow, without great care it makes contact on the drop: we have a foam bow "fender" that stops damage, but that's not ideal. Two up, it's much easier.
