Was thinking of using a single block at the mast foot. However I'm not sure if the mast is far aft enough. What do you think of these arrangements? [url="http://mauriprosailing.com/Harken/Harken-Trimming-Systems/Self-Tacking-Jibs.htm"]Pictures and info[/url]

I'm intrigued about option 3, where it almost seems we could turn this "jib boom" into an auto-whisker pole?

Steve, the jib would have to be less than 100% to accomodate any of those setups and maintain shape.

There was a thread a month or so ago about setting up a self tacking arangement.

I'm not quie obsessed by sail shape, but may be getting that way, and all of those systems seem to forbid decent jib shape. Close hauled (typically the point of sail where you'll tack frequently) requires good sail shape, and I'm not sure how they work out.

I've heard Option 3 called a club-footed jib (no offense intended to anyone born with that problem). I sailed on a ketch once that had one. It actually works quite well for pleasure cruising, and it's terrific for single-handed sailing. The jib tacks just like the main so, in theory, there is very little sheet adjustment required. The boom, and therefore the sail also, would have to be short enough to clear the forward lowers. You've also got a problem with placement of the pivot base. It would have to be behind the forestay about where the anchor locker is on the C-25. It would also have to clear the lifelines.

Steve,
Take a look at this thread. Seems to work for the 110 on our boats. Cheaper, too!

Forgot to mention that I saw Simon's post and Frank's mod. Thought I would run these other options by you. I think I'm going to go with the simpler solution. Thanks.

"I'm going to go with the simpler solution."

Simple? Nothing's simpler than rigging three blocks and a 2nd sheet like I did. Also, the sheet can begin at the starboard base of the mast, run through the starboard block, up and through the jib clew block, down and through the port block, then aft to the port winch. The standard jib sheet can remain relaxed and used when you want a flatter 110 foot or want to heave to. The self set up works best when the jib is only unfurled about 90%.

No need for a spendy fordeck track or jib boom.

Works for us!

I reread my last post and agree it is not clear. What I mean't to say is that I want to do it just like you did Frank. Thanks about the 90% tip, I couldn't see how fully furled out it could work well. This mod will be great on my small lake since we have to tack so often.

Our boats really need the punch of a bigger headsail. I wuld be really hesitant to give up the power for ease...

If you retain the standard, non self-tacking sheets, you'll have the option of using either sheeting setup depending on wind strength and necessary tacks. For long stretches on one tack we use the standard rig and not the self-tacking.
