While there are prettier anchors to put on that classic clipper bow, I think you will find it worth the trouble for the modifications.
After two years of liveaboard
cruising, the Rocna was one of the best buys we made for our 44' cat. Sure, the folks on the dock
laughed with I hauled that 33kg monster on to the foredeck, but it has held us nice and steady through several pretty good blows.
The only problem we ever had was purely due to my own mistake. (We hit the only patch of thick grass in the whole anchorage. I got in a hurry, didn't see it, and didn't dive on it. Lesson learned. Not even the best anchor will compensate for poor seamanship.)
Although using a trip line/anchor buoy can be a problem in some places, when in a thick mud bottom, I've started using one, anyway. We had a couple of times when the anchor was so full of mud that I was concerned about getting it up. The trip line takes care of that worry.
