We are planning the next couple of seasons in Sweden and Finland and contemplating investing an Ankarolina tape reel mooring system that is very popular over there and would make mooring to a stern buoy easier, especially single-handed.

Ankarolina offer four or five versions, but I don't quite understand the breaking strain ratings. The cheapest is A 24M tape that is 25mm wide, rated at 2500 (pounds I think) and recommended as suitable for mooring a boat up to 50ft l.o.a.
Next is a 35m x25mm unit rated at only 1500 BS for boats up to 21ft l.o.a , followed by a 56m x25mm version rated at 2500 BS and recommended for boats up to 50ft. ( Sorry about the mix of units nut that's the way they describe it).

If I understand correctly from the product description, the shortest 24m version is specified for mooring, while the others are rated for anchoring. Tape width is the same over all three versions.

For me, the 35/25 option would do the job for the stern buoy task but our 33ft boat is well over the anchoring rating. They don't give a mooring BS figure, but looking at the other versions I would expect it to be more than adequate for our boat.

Anyone has experience of this kit? My gut feeling is that I would be happy to use it for hitching to a buoy or as a shoreline, but to deploy a stern anchor I would use a proper rope rode, especially if conditions were going to cut up rough.
 
We had the lightest guage on a 30' boat.

Lying to the kedge with a line ashore we had no problems with about 35Kts directly on the beam. Huge load. Flat water though.
 
Yep

We have one.

Ours is stern mounted - where I imagine yours will be. It really doesn't take much strain - not like under bow anchor swinging around in wind and tide. It's really only there to keep you away from the shore and pull against the ropes that you've got going up to the trees or rocks.

BTW I'll be putting ours on the for sale forum in the next month - can't think we'll use it much now we're in UK waters.

Cheers

Geoff

The breaking strain values are kilos, not pounds. The tape width is 25 mm for the smaller versions and 35 mm for the larger ones.
I have not used Ankarolina myself, but as you say many people over here use it – mainly for the stern anchor. If you are going to spend some time here you will probably end up doing a lot of stern anchoring, so I would suggest you consider using the kit for this as well.
The right model for your size of boat would be the A56 (56m, 25mm, 2500kiloBS) as 35 m could be a bit marginal for stern anchoring in some places, given the boat size.

Thanks for that. The site I was looking at did not make clear the BS strain values they were using. I has almost decided on the A56 and you have confirmed that I was on the right track. I would assume that once anchored or hooked up, you would belay the tape around a stern cleat, I don't think it would be good to rely on the reel and bracket to take the strain.
 
Had one on a 30 ft boat which I bought in Sweden. Mounted aft. Very common in Sweden. To be honest, I wish that I'd remove it from the boat before I sold it. Useful piece of kit.

I'd also send a pm to Geoff but it looks like it's far too late already!
 
Of course we have one, and as many have already said...useful bit of kit.
The 24 that you refer to is 24 meters long 26mm wide and breakload of 2500kgs.
And it's meant for anchoring, hence the name 'ankarolina' (basicly mean anchor rope), so I don't understand why you'd opt for a 'proper' rode when achoring?? As that's the sole purpose of this bit of kit.
You just drop the anchor with a couple of meters of chain a few boat lengths out when approaching the bank, then the drum just allows the line to run out.. simple!
 
Sorry... just to add, as said we have the 25mm/2500kgs one on our Najad 343 approx. 7tons, and never any problems:)
 
If you read my original post, what I cannot understand ( in the description by Pro Boat who supply the trade here) is why the shortest 24m unit is rated at 2500 kg and is specified for mooring boats up to 50ft l.o.a., while the longer 34m unit rates only 1500kg BS and is said to be only suitable for boats up to 21 ft l.o.a. and is specified for anchoring ( on their description the shortest 24m set up is for mooring) I don't know if there is supposed to be a difference! Confusing isn't it?

As other posters wrote 24m is a bit short for anchoring
Here is a table I found, seems there are two different bands with width 25 mm,
guess that making a smaller width than 25 mm (for BS 1500 kg) would make it difficult to use.

Dim. Length BS
25 mm 35 m 1500 kg
25 mm 56 m 2500 kg
35 mm 70 m 3000 kg
35 mm 56 m 3000 kg

I disagree 24m is certainly not too short to anchor the way its designed to anchor, that is off the stern in shallow, sheltered water close to land. It's not the 3 or 4 times the depth ratio that is normally needed.
 
You're likely to be using the Ankarolina is very sheltered bays (sometimes almost landlocked) with soft muddy bottoms undisturbed by tide. You also won't be swinging at anchor as you'll have tied the bow off to a wharf or something on the shore. (You do cleat the tape off around an ordinary stern cleat by the way). So chaff of the tape is not a worry.

It is going to be rare that you find yourself anchoring in the middle of a bay off the open sea with the wind howling and swell rolling around the corners. If you do I suggest you go back to using a bow anchor and chain UK style.

I don't remember seeing anyone use the tape to tie to a mooring buoy. Mooring warps are normal for that, although a few boats have hooks that they fit through the ring and keep in place under tension (saves having to rattle off a round turn and two half hitches as you coast by the buoy).
