That's what mine is like - it appears to have strengthening/Teflon? at the feed in end, to make it easier to slide in. Still a bit of a struggle though - ideally the bolt needs to be a size smaller to make it easy.

I think the special tape is called Super Glide Tape - Kayospruce sell it but they don't seem to show a picture of it.

There can be advantages to a loose footed main in light airs, too, as it allows a fuller shape, though I've no idea whether I'll notice the difference in practice.

Whether it makes any real difference to boat performance I cannot say, but a loose footed sail is much better if you are an inveterate sail tweaker as I am. You can get a much better shape.

However, with a loose footed sail you still need the sail cover to slot into the boom because if you dont, you end up with the bagged sail flopping to one side or the other of the boom and looking a mess. As well as still having all its weight on the lazyjacks. Which is why I am waiting my new sail cover, much delayed , from Crusader.

Stack pack

Personally i always prefer to remove the boltrope from the foot of the mainsail and fit the boltrope directly to the foot of the cover. It makes fitting it a lot easier and means you can remove the cover without needing to take the sail off should it need repair or a mid season clean due to excessive fouling from sky rats. Most boom sections are strong enough to not need an in boom foot and the idea that it looses power is laughable when you see the disturbance caused to the airflow by the stackpack. i. I always fit ties in the centre of the cover to enable me to roll the cover up and secure it when the wind is up or on extended passages. If you need any pictures of the above let me know.

I dont think the so-called 'nylon' tape is that at all.

It is very thin, very strong, non-stretch and very slippery.

I am sure any canvas maker would tell you what it is called and where to get it.

Normally the white bit that threads into to boom is a heavy sail luff tape,usually about 125mm wide and 7 or 8 oz.Terylene.
Its strong enough to take the lazy jack pull and put up with being threaded and trapped in the boom groove by the mainsail bolt rope.
It does have the advantage of being trimmed and sealed so it doesnt make to much of a lump,when feeding it in.
.If you used acrylic canvas here ,its all too bulky to thread in the groove.
Also acrylic is a brittle fabric which can tear easily when scraped along sharpe boom entries.
