Answers to some technical queries at http://coxengineering.sharepoint.com
As an example. On our 32ft cat (similar weight, probably greater windage) we used 20m of 8mm chain + 50m of 14mm octoplait spliced on. We used that combination for 10 years plus in coastal waters and it always proved perfectly adequate. Only if it was very blowy or deeper than average did we get to use the rope.
In view of the reports about (non) resetting at tuirn of tide I would not have used a Danforth type anchor, we used a Delta.
I was just trying to suggest that maybe the basis for your choice of ground tackle does not have the right priorities.
Surely the starting point is what is the best design of anchor for general anchoring and then how is it best to deploy and handle it. A modern plough type anchor (like the Delta, but there are of course many others) is perhaps the best general purpose anchor and in the size that you need for your boat it is easily handled with a windlass and adequate all chain or mixed rode.
If you are convinced that the Fortress is your preferred choice, you need to recognise its limitations and that the choice of chain/rope will be the same.
Apologies, but I can't read that SWMOB without visualizing this guy skippering a boat.
Her design is also such that a windlass would need strengthening chain lockers etc. We may still have an eye on racing her, but she is a compromise we wanted a fun, fast boat without to much domestic stuffs to go wrong.
Presently the anchor is stowed under the berth in the main cabin and would take both of us to get it and the chain on deck. Without damaging us or the boat, this needs to change.
We are looking to compromise, keep the chain and anchor in a basket below the forward hatch. So we can lift a basket on deck and have the rope come out of another basket kept below.
With regard to resetting I have sailed with Danforths most of the time and never had a problem. There is a proviso or 2 here:
1) We have always had all chain rode,
2) If overnighting we normally extended to 4-1,
3) If weather was up we would ensure we would check her as the tide turned. Its been so well drilled into me I get up when the tide turns regardless of weather (it normally a great time to be up, "no love I will be down in a minute, just going to wait for the tide to turn. Can you pass me up the remains of the Whisky/ Rum/ Wine coffee?") .
4) I was also taught never to use astern to set the anchor in, walk it to the bottom extend to 2 1/2 WD on deck, wait till she is being brought up, then put 3-1 in water and check she is brought up (I believe the logic is that once it has a grip it will carry on digging. Dig it in 2 far and by the time the forces are great enough to turn it will never reset).
I am not saying I am right defiantly right (Again if I thought I was I would not ask here) but hope you can understand where and why we are trying to reach a compromise. Light enough to lift but powerful enough to hold, in normal conditions.
What would you guys say to the idea of:
1) Keeping the big old CQR down low in the middle of the boat (where weight should be) with its 10m of chain and however much rope as a "hurricane anchor".
2) Then get the Fortress as an every day anchor with the knowledge as the tide turns or there is weed we need to be careful.
Most of our anchoring is done in winds under F5, I am not in the game of sleepless nights worrying about a boat. There are normally enough marinas around if the weather pipes up.
If we get caught short and the weather turns foul and we can piggy back anchors or lie to two or what ever.
And as for the post title 20mx8mm of Chain followed by 50m+ of rope sounds to be the consensus?
