Anyway, I got a 31 ft Beason (more info here
), a Swedish-built sailboat from the late '70s that I'm fitting for an Atlantic Crossing
next year. The plan is to sail from Europe
to the Caribbean
and then cruise
around for at least a year.
This is on a tight budget and I am now considering anchor options.
I currently own a 10kg Bruce and a 10kg Danforth anchor, 5 meters of chain and some anchor rope
. No windlass.
I've been thinking about two options:
- Expensive option:
Keep the Bruce as a stern anchor, scrap the Danforth and invest in something like a Mantus anchor which I then would up-size + 50 meters of chain and a Windlass to use in any anchoring situation. Would an up-sized Mantus anchor be enough in stormy weather?
- Or the cheaper option:
Keep both of my current anchors. Buy a 10 kg Delta anchor, 20 meters of chain, and around 30 meters of rope. This option is way cheaper and I wouldn't need a windlass either.
Those idéas might be really bad, I don't know. Do you guys have any input? Any better idéas?
I have no experience of cruising, sailing by the swedish coast is something completley different than what I'm planning so any help is more than welcome!
So for the length and beam of your boat you can expect about 2000lb of anchoring loads in the worst cast. That’s from the ABYC anchor load table interpolated for your dimensions using 42kt wind
For that load 1/4” (6mm) G43 chain and 1/2” (12mm) nylon line would hold fine. If you went with BBB or G30 chain you would need to go up a size and the price
would be similar to the G43 chain but it would be heavier.
If you don’t have a windlass you can get away without a bow roller. Keep in mind that even pulling up by hand the bow roller makes the work
Inboard from the roller should be a chain stopper. If you don’t have a bow roller you don’t need the stopper. Even if you have a windlass you should have the stopper, the windlass should only be loaded to raise or lower the anchor. With a stopper it’s reasonable to motor
up to the anchor and raise it by hand; you can sit on the foredeck and pull up a length of rode
and the stopper will hold the load while you lean forward for the next pull or just catch you breath. The chain stopper, and all cleats
on the boat should have over-sized backing plates
under them with cleats
held down by 4 bolts.
Whether you have a windlass or not you should motor
or sail up to the anchor.
I would keep the 2 anchors you have, the Bruce as a backup and the Danforth for ultimate holding power in a storm or in really soft bottoms where it will hold better than even the NewGen anchors.
The old anchors are not bad or crap, they just aren’t as good as new anchors by reasonable margins. To a point you can trade money
for weight in choosing an anchor. Chose an older heavier anchor for less money
over a new lighter anchor for more money. As an example a 35lb (15kg) Delta
retails for $226 vs a 26lb (12kg) Vulcan (Rocna sub-brand) for $320, both at West Marine
. Is one of these anchor going to hold better than the other? I doubt the Vulcan will hold much better than the Delta if at all. The Vulcan is 1 size up from recommendation the Delta is 1.5-2 sizes up.
The "up to a point" caveat relates to how heavy an anchor you could pull up. If you are pulling up by hand, a 44lb (20kg) anchor is probably as big as I would want to deal with on a regular basis with a windlass. The 20kg Delta probably would hold significantly better than a 12kg Vulcan at a cost of $344, $24 over the 12kg Vulcan.
For anchoring I prefer to use mostly chain unless I am absolutely sure that there is nothing to chafe line on the bottom. Since chain does not stretch like nylon and centenary is pretty much gone by the time the wind gets to 30kt I want some line out to prevent shock loading the points where the rode
attaches to the boat, the chain stopper or a cleat.
For my primary rode I would use 100' (30m) of chain and 200' (60m) of line. For a 3' bow height that would let me anchor in about 21' with 5:1 scope
with the rope-chain joint 3' clear above the seabed in dead calm, no current
conditions or 29' with 4:1 scope
With 190' of line out in heavy conditions I could have 7:1 scope in 38.5' of water
or 10:1 in 26' of water
, or 5:1 in 55' depth
All that said, I would want more anchors on my boat than just these 3 and would sacrifice a number of amenities in order to afford them. There would be no wind instruments
, no CodeZero, no refrigeration
until I got my 4th anchor.
You may not want to talk about what else you are putting on the boat because of the amount of abuse that people will heap on you for not having this or that item which they think is absolutely necessary or why are you wasting your money on some gizmo they think is absolutely worthless.
