Double-Mainsheet #2

After seeing the previous arrangement up close, and realizing that it was held together with 2 screws with only 2 engaged threads, I was unhappy!

So I used the original base of the double-cleat, much beefier with a ball-bearing swivel base pressed into it, and did a second cobbling. This swivel did not come with a fairlead of any kind as you are supposed to purchase a double-ratcheting block for it. I had two swiveling fairleads with ss clamps meant for railings/dodger frames: I took them apart, purchased some u-channel aluminum, drilled some holes it it, voila! Mounted it all up, ran the double-mainsheets and it worked. So I set the 4 mounting screws into epoxy today. . .

Comment by kim whitmyre on May 11, 2011 at 10:32am: Hi Adriano,

The ends of the purchases, at either side of the motor, are both attached to the clew of the mainsail when it is raised. These allow the mainsail to be positioned port or starboard, like a traveler system. They also allow for better control in trimming or easing the mainsail. For example, once you have the mainsail positioned, the leeward mainsheet can be trimmed to flatten the mainsail, or eased to increase draft in the mainsail. So the double mainsheets give a better ability to shape the mainsail than a single mainsheet provides. . .If you feel the need, that is!

Comment by paul anderson on May 11, 2011 at 1:12pm: kim it looks like a neat system that gives you more options than a single sheet.

Comment by Rogerio Martin on May 11, 2011 at 2:08pm: Works works, but very complicated system. Why did you do that? To rid the sheet of the motor and camera?

Comment by kim whitmyre on May 11, 2011 at 2:43pm: Haha! I did say "if you feel the need." It's not really that complicated, it's just another mainsheet! Being able to fine-tune the shape of the mainsail (any sail!) is absolutely worth it if you want to get the boat up to its potential.

The location of the camera is actually the mount for a solar panel; this does give much more clearance for the panel, but the sail trim is the primary reason for the change.

My mainsail does have cunningham grommets, which is another way to flatten the main, but I would have to fold the dodger to the mast to make room for the cunningham purchase. Which I would do! ;~)

Comment by Rogerio Martin on May 11, 2011 at 3:02pm: If for sail trim...is a great reason. I like to go fast...hehehe

Comment by Rogerio Martin on May 11, 2011 at 3:04pm: And cam? Where the go pro sailing images???? I waiting...

Comment by kim whitmyre on May 11, 2011 at 10:59pm: Sailing video coming up! I'm going to try to mount the camera higher so it sees out in front of the bows. . .This may give a less distorted view of the mainsail foot hopefully.

Comment by adriano meis on May 12, 2011 at 6:55am: hmmm. now it sounds better. I'm waiting for more pictures/movie

Comment by Ricardo Aráoz on July 28, 2012 at 9:23am: Hi Kim, really like it. One thing though. Is a 4x purchase really necessary? Could it be done with a 2 or 3x? What is your experience with that?
