Don't want to prolong the thread unneccessarily as Puddock seems happy with his answers but I am intrigued by the substitution of a 55kg. Rocna for a 25kg. Delta.
Where were you planning to go?
I am of the school that you never know where and in what your life will depend on your anchor holding, so on all of my boats I have always tried to have maximum feasible ground tackle on board.
I realize that UK sailing is not as demanding as you chaps have a world-class port every 10 miles or so (it seems), and are thus never far from a good hidey-hole, and besides that spend most of your nights in port anyway. I grew up sailing in the US where there may be days between decent ports, and while cruising you spend almost all of your nights at anchor, sometimes in storms.
My only really frightening experiences over decades of sailing have been anchor-related.
So when I upgraded the ground tackle on my Moody 54 I basically chose the biggest anchor which I thought would fit the bow roller. 25kg was definitely undersized for the boat, which is about 55 feet LOA and 22 metric tons loaded. 55kg is pretty typical anyway for hard core cruisers in 50 to 55 foot boats. It's only one size bigger than the Rocna recommendation, which is 40kg.
The 55kg Rocna is probably overkill for the UK South Coast, but where ground tackle is concerned overkill is a good thing. There is no such thing as being too secure at anchor. Besides that, I plan to keep the boat for a long time and plan to roam far and wide and I will certainly be in some places which are more demanding of my ground tackle, than the UK South Coast.
The anchor doesn't look stupid on the bow of the boat (I think it looks about right), and the extra 15kg compared to the recommended 40kg anchor don't affect trim at all (I have 100 metres of 12mm chain on board, the weight of which dwarfs the weight of the anchor itself). It is, however, somewhat difficult to handle, and required work on my windlass clutches and the installation of a giant (and costly) Kong swivel to get it to self-stow properly. In case the electric windlass were to fail -- God forbid -- it would be a real challenge getting the ground tackle up, but again, the chain would be the biggest part of that problem. But I consider all of this a small price to pay for sleep at anchor!
Incidentally, kudos are owed to Craig Smith of Rocna, who was very generous with his time and knowledge in helping me figure out how to make the anchor work on my boat. I know he irritates a lot of people here (including myself) with his tireless (and shameless) propagandizing, but I got to know an entirely different side of him when I encountered problems with my installation! Thanks again, Craig.
