Stackpack problem

[Boo2]

Hi,

I've just had a stackpack made and there is a problem with it which I would like the forums advice on before talking to the vendor. Sunrunner has a mainsail with a bolt rope but this does not extend all the way to the clew, instead it stops about 3/4 meter or so forward of the aft end of the boom and the sail is relieved to allow the reefing lines to be tied to the boom.

The stackpack I've had made has a mesh piece at the bottom that goes in the boom slot and is trapped by the bolt rope in the normal fashion. This leads to the issue that aft, where the sail has no bolt rope, the stackpack is not retained to the boom in any way. There are two obvious solutions, one is to sew a piece of bolt rope into the aft region of the stackpack itself, and the other is to sew in straps that tie the stackpack to the boom.

I'm completely confident the vendor will fix the problem but I just wanted opinions as to which of the above fixes would be preferable in practice, or is there a better way altogether ?

Thanks,

Boo2

I have exactly the same set up. The stackpack mesh should finish in the same place as the bolt rope. I then have ties from the end of the stackpack to the end of the boom that keeps the rear of the stackpack in places. I would have thought the stackpack would have been supplied with these or at least eyelets which you could attach them to. The stackpack shouldnot go right to the end of the boom but should reach to a little further than the leech of the sail.

If you sew in a bolt rope then you won't be able to tie the reefing lines round the boom without cutting into the mesh.

My stackpack has dedicated slots for the reef lines so they could be accomodated easily
The main problem will be actually fitting the whole thing
i am assuming that you are sliding the stackpack plus the sail into the same groove. That is a real pain trying to rig & de rig each year
On my boat the 2 sides of the stackpack have their own tracks. this means the stackpack can be removed with out the sail & vice versa
I suggest that if further alterations are needed then you might consider getting some track ( use the stuff that caravans use for awnings) & pop rivet it to each side of the boom

The bottom of our stackpack is completely open - it's effectively two separate sides held together by several short pieces of webbing. Each of these linking straps has a kind of sail slug attached to the middle of it, and these go in the groove in the boom and keep the whole thing in place. Maybe your flappy aft end could have one or two of these plastic slugs to keep it in place without blocking the reef pendants?

Same as mine - I have sail slugs in my boom slot at the rear end.

My stack pack is in 2 pieces. Port & starboard. Each is attached to the sail very close to the boom by zips. In your case you would only need zips on the flappy bit.

So you have zips sewed to the sail itself? That's a novel approach I've not seen before.

Nor had I until sail maker convinced me that it was the modern way to attach stack pack. I was sceptical but it certainly works.

We've just had the bolt rope removed from the mainsail and sewn into the stack pack - it was just too awkward to thread the stack pack and the mainsail on together and I wanted to be able to change the mainsail easily too. Plus the loose-footed main is now so much more controllable. Win-win for us.
