Asym. rigging without bowsprit. Dual tack lines?

Hi all -

We finally got an asymmetrical spinnaker for our 1985 Tartan 34. There's no bowsprit and the only place for a block up front looks to be an inch aft of the forestay. We have a furling jib and this old furler has a *very* large drum ..... so I think it would hard to get a line running up to an ATN without chaffe on the furler drum..

We got it flying last night and it looked great .......but only on a port tack. We can't jibe it over becuase the tack line has to head out behind the furler and pulpit. Therefore on the starboard it would chaffe as it rubbed across the bow pulpit. (and probably pull my light fixture out too)

If I rigged it differently with the tack line heading out on the starboard side I *could* get the stardboard tack to work but then it would rub when we went to a port tack.

So I got to thinking ...how about twin tack lines? One port, one starboard.

I put a double block just aft of the furler and rig one line for each tack ( I think I've seen multihulls use something like this). As we switched tacks we would ease the port side tack line (that was going to chaffe) so it just goes limp while coming in on the starboard tack line.

I wanted to bounce this off the group here before I go and do something stupid and/or expensive though. Comments welcomed!

Sounds like a solution.. but you're much better off to get the lead forward of the forestay. Do you have an anchor roller? We have a double anchor roller but only one rode.. I run my symmetrical Spinnaker downhaul out under the spare roller and use that as my tack line when flying an assym. I find that running it up inside the pulpit is best for our arrangement; it nicely clears the furler drum. Our roller assembly is very strong (the vertical lift on a lightweight aftermarket roller might be a bit much)

I've seen others add a large shackle to one cheek of the roller assembly and put the tack block there too..

But if there's no possible forward attachment the double line idea sounds like it's trial-worthy!

This pic shows a general what faster was talking about. A block in the center of the double roller, with a cheek block at the aft end of the anchor locker to redirect the tack line to the top/back part of the cabin top where one can control the height etc

Here is a side pic of the spin flying.

Re: Asym. rigging without bowsprit. Dual tack lines?

Wow. Don't know how I missed it but there's a small padeye on the anchor roller. Rigged it up yesterday but Lake Erie was completely becalmed by the time I did it so haven't tested it yet, but looks good to me.

mrs_dergon, who opinion is not to be disregarded lightly, is somewhat concerned about "lift" forces on the anchor roller. The padeye is only about 4 inches forward of the bolts for the roller but she is worried about it pulling out under load. Thoughts?

oh -- and thanks for the prompt help so far!

Thanks, bob!

But back on-topic.

What do you all think about the risk of clipping the tack line to the anchor roller cause it to tear out. The questing is whether the "lift" from the tack line is something it is built for. Or am I just being paranoid?

Many people do that... it depends on the robustness of the setup. Many anchor rollers are integrated with the stem fitting and if heavy enough construction should be fine. What I'd worry about are the aftermarket 'bolt on' rollers, esp the longer overhanging ones..

Ours is integrated with the stem fitting; and I run the tack line out under a spare second roller. It's holding up fine.

Re: Asym. rigging without bowsprit. Dual tack lines?

My pic does not show it well, but I have a double roller, and drilled a smallish hold in the middle, put a clip then the sheave with the line thru it. You can see the sheave and u-shaped fitting, but not the attachment in the photo above showing the tack line routing.

Re: Asym. rigging without bowsprit. Dual tack lines?

sounds like you are heading the right direction. I have(had) sim prob attachment point was behind fruller drum so mad a bridle of1/2 dacron easily replaceable. I ran it out under the bow pulpit and it works great. very little chafe and easy to tack. I have a very robust double bow roller that I attach to now. now it clears everything and works perfectly.
