asymmetrical spinnaker


Eloi Bamberg
 

Hallo,
When i we bought our SM2K, there was an asymmetrical spinnaker (original option with snuffer from Amel) on board but the seller couldn't tell me how to fix it at the bow of the boat. Does anybody know how Amel had planed to fix it at the bow.

regards,

I made a bow sprit that sticks out about 2 /12 feet from the bow with a articulated block (Harken)..

It is about 1 ½ inches in diameter and is removable when not used.

One year ago, I installed a Code Zero. I wanted to do without a bow sprit and after a lengthy discussion with the sailmaker ( North ) and the rigger, we finally decided to use, as attachment points, the central roller for the bow and the small aluminium nose at the Masthead end, adding an external halyard.
I was afraid that the rolled Genoa and the rolled Code zero would sit too close for safe handling but, as it was, they resulted perfectly parallel, at a safe distance and worked impeccably, The attachment to the central bow roller is the simplest thing: a dynema closed loop doubled around the roller and blocked by a common shackle to the stay sewn into the Code.
Also the reefing line is a closed loop, brought back to the cockpit and, via a block on the rail, to the electric primary which, giving us (aged couple), the. pleasure of an electrically operated furling and unfurling

We had a "Code Zero" with the same setup, but lost it in unpredicted bad weather in Vanautau some years ago - actually it was my fault, should have taken it down before setting off, but we live and learn.
Now we have an asymmetrical spinnaker with a snuffer which attaches at the foot in the same way as the code zero, but no furling lines.
The hoisting halyard is the same, through a block on the front of the mast head.
We snuff it behind the main when running off and then drop the sausage and put it away.
Very simple, and an awesome sail when reaching, in conjunction with the mizzen ballooner.
Cheers

Paulo/Alan,

if you can please post a photo of the Dynema loop connection to the bow roller and the block location.  Just looking at ordering an asymmetrical so would be great to incorporate you design...

cheers

Alan I would like to see some pictures as well please - especially how you connected the furler at the top of the mast if you have that?

This is interesting to me as I have looked into doing this previously (not on an Amel) and was told by a rigger that I would need to add a crane due to the masthead rig setup and then it would only handle a furling asymmetrical - not a code zero due to the additional loads and potential of getting it caught on the forestay during furling. This was on a Selden mast and the crane part (https://support.seldenmast.com/files/1498459501/597-207-E.pdf) seems to confirm this as it specifically states "Only for use with gennakers, not Code 0 sails".

Thanks,
Alex

Hi All,

Sorry, I don't have any pictures. I haven't been on Elyse since March 2020.
We don't have a furler for our asymetrical spinnaker, we have a hoop and sock for dousing it.
The whole assembly like a sausage is hauled up with the halyard. Then there is a continuous line that is used to hoist the hoop and sock to the top of the halyard and the sail comes out. Dropping it is the reverse. Run off with the main out so the sail collapses in front of it, pull down the hoop and sock, lower the sausage with the halyard.
When we had a code zero type sail it was on a furler on it's own stay. The top end had a swivel to attach to the spinnaker halyard, which was hoisted with the halyard and then unfurled - it was simple arrangement.

Cheers

Alex! 

last year we bought a "Code 3" on a facnor furler all supplied by Incidence sails. It was no issue at all to use it, I attached a halyard at the top of the mast and just hoist it. We got it at the end of last season so have only used it in light wind. We can sail from around 75 degree apparent wind to 180 degree in light wind. it is designed for maximum 17 kn of wind. I think we will have great use of it the size is 115 sqm.

Hi all,
Hope to be on board tomorrow and make some photos. Also , I am trying to trace back all the pictures taken during my discussions with the rigger as this has been a long story, everybody trying to convince me to accept the standard solution of a bowsprit, fixed or removable, which I didn’t want.
Back soon with a post

Hallo,
Based on the answers of this tread and the Amel official manuel, here the 2 solutions i figured out. I will try both of them when we can sail again.
solution 1 (roll for second anchor)


solution 2 (official Amel version)

Is there a reseason why you do not simply use the center roller, taking the tack line under the roller, and forgetting about the line fairlead?

Hi Paolo,
I had a removable forestay made. It sits about 2 1/2 feet forward of the bow. It is only 3 feet long in total. I has a Harken swivel block on the end and mounts in about a minute . I store it in the port cockpit locker.

I think if the sail is luffing there is a risk that the line get stucked, so i prefere this setup with more guidance.

Eric,
Your solution of a short removable bowsprit is sound and well proven, no question about that, and I much respect it. Mine is only a matter of a personal preference, and I took a little bit of a chance trying something of which, at least in my area, there was no .previous reference. Fortunately everything went well and I’ll put some photos on my next post

Hi all,

Here the documentation of my approach to the Code Zero (better: G Zero to use the wording of my sailmaker, 92 sm, integral anti-twist halyard, detachable bow roller). The video shows the final check of the clearance between the rolled genoa and the dummy halyard I used for the test, using the central roller as a tack .Both rigger and sailmaker agreed that everything seemed ok so I decided to proceed.

The photos show the dyneema strip (trebled) in an open loop that goes around the rubber central roller and is  made fast with the snapshackle. Note: in my case the loop must be as short as possible to avoid twisting, as I use a roll-on Code D with integral anti-twist halyard sewn in and its attachment point must not turn. As it is, the dyneema loop makes about half a turn then stops, allowing the halyard to start rolling up the Code.  If somebody is using  a sleeve instead, this point is, obviously, not a critical one. The last two photos show the  code in place, rolled at rest and in action. It can be seen that the clearance is not big but sufficient for the purpose, and in one season use, the system  proved  basically trouble free

Hi Paolo,
We have been using this setup for 18 years without any problem
I like it a lot as it is in cleaner air and is very strong.
My gennaker is 1 1/2 oz material and we can fly it in 25 knots true.
When I first received Kimberlite we hooked up the gennaker to the anchor roller we wound up
bending part of it in about 20 knots. We had that sail up that time for 7 days straight in the trade winds from Europe.
