You guys are already far more knowledgeable about the Stackpack than anyone here at Sailrite. I am affraid I can not offer any more help. Please continue to post your results as I see this forum topic is very popular. If anyone has pictures we would be happy to post them.
Thanks, Matt

Ernst,

You are correct in thinking the membrane is visible when the sail
is up. If you were on a boat in the Virgin Islands you sure did have a
Doyle Stack Pack however they seem to use the earlier version there, as
I am sure it is much less expensive.

There is an installation manual on their website to give you some
help. It shows what the system looks like and how it is installed.

If you need some more ideas please email me.

I am thinking if I ever make another one, I pretty well have it figured
out........I have to work around what I made last year, and since I
have seen the real thing I know what to do now...pretty well anyway.

Yup, it was in the Virgins (BVI). Are you saying the older version (which we likely had) would not have the membrane? If yes, it is good news because it worked great and did not flap excessively.

I actually found the Doyle installation instructions somewhere on the web but I don't think they talked about the membrane thing. May be wrong, has been a while.

I am, unfortunately, far away from having pictures, other than those in my mind

Matt, do you know what material the 'soft tape' could be that carib008 suggested to use for this membrane thing? I understand its function is to pull the top of the canvas towards the sail when the sail is up. Thanks.

Hi go to

www.Doylesails.com/stackpackmanual.pdf

to see a good illustration of the pack.

I asked  them for a   quote for a pack for my boat and this is part of the email I got...

If you are considering retrofitting your existing mainsail with a complete Doyle StackPack mainsail handling system the price would be $ 2650.00.  From our telephone conversation, earlier this afternoon, I suspect that the StackPack price was greater than your expectation.

There is an alternate you may wish to consider...a "Cradle Cover".  A Cradle Cover enjoys many of the same features as the StackPack however as it not integral to the foot of the sail, it represents a significant savings over the price of retrofitting an existing mainsail with a StackPack.   The price of a Doyle "Cradle Cover" is $ 1650.00.


The soft tape is a fabric that is made quite wide and then cut into strips to use for edging ?????

I do have a picture of the cradle cover mentioned above but not sure how to post it....... this is what my older version looked like almost exactly but we were not happy with the way it flapped around. The battens I am using are too light and that may contribute to the flapping issue. The real pack has round battens an inch or more in diameter. I used flat little skinny things... and would use a much heavier type the next time.

And for some more hints for how to attach the pack to your sail or boom...

You can sew the pack to the sail at the foot.

If you have a boltrope you can sew the two sides of the pack together with a small strip of dacron and then side the assembly on with the bolt rope.....you will have to pull hard to get the boltrope and dacron in the groove.

If you have a loose footed mainsail, just sew the pack together at the bottom and then sew on some slugs and pull the assembly in the track if you have one, if you dont then you have to attach the pack with some kind of straps around the boom to hold the pack on.
 
I got these methods by asking a company that is making their own version and selling on internet for a reasonalbe price.

As I said before I used velcro straps between the slugs on the mainsail and it held the pack in place quite nicely. At this point I may just keep this system for now until I figure out where to sew the membrane on the sail... it will be determined by where the pack sits on the boom in relation to the sail, this is made more difficult by the fact that mine is already made.

I am hoping to get to the next step, this week sometime( sewing the membrane to the sail if I can get it under the arm of the machine..otherwise I will have to take it to the sailmaker who has a longer arm or wait until I get my old singer fixed).

 I can send the picture of the cradle cover, just send me your email ......

carib2008@yahoo.com

Hope this helps.....

Here are the pictures of the Cradle Cover

Check out my other blogs if you like.

Also here is the site for another type of packing system that is much easier to make.  I did not want the lazy jacks on the exterior of my pack .

check it out as well.

Hope this helps,

    Hi Carib,

thanks for all the tips and links.

As for the battens, I plan to use PVC pipes from Home Depot, 1/2" diameter, with endcaps to avoid chafe. Based on your experiences, perhaps a greater diameter would be justified (3/4" or even 1")? In either case, the material is very inexpensive and widely available so I can experiment with it.

For the foot, my sail has a boltrope and I plan to add slugs to its foot. I will also put slugs on the bottom of the cover and then slide them on alternatingly. This is what Matt Grant suggested and it seems like a good idea.

So far, it is all theory -- first have to finish my bimini...

Oops....long day..

Ernst , we also talked about using PVC , and the original has a round batten of about 3/4 - 1 " in diameter...I really feel I will have to replace the battens on mine next year....it is up now....and hopefully will function okay....

When you get around to starting your stacking pack.....email me and I will give you some hints as to the order of construction.....it will make it much easier......I did mine the hard way.....and have to live with the consequences........Oh and the membrane I think the next time I would use a light weight sail cloth.....it does not really have to be that strong.....

Good luck with the bimini...I will start my dodger/bimini/enclosure ...next spring....hopefully....after I figure out how to bend the SS.

Thank you, yes, some guidance would be highly appreciated. But the project will surely have to wait till winter, now it is time to enjoy sailing not sewing!

I did some experimentation with bending 1" stainless steel tubing, with a pipe bender (the hydraulic type you can even bend thick-walled plumbing type with). T'aint easy. I found that EACH bend of more than about 10 degrees kinks. I think one has to make many small bends of less than that, like nine bends of 10 degs for a right angle. Oh, and I filled the tubing with sand and compressed it as much as possible but it did not make a difference.

Good luck!
--Ernst
