Ordering a new main for my J/92 classic

Hi all,

I’m ordering a new mainsail from UK Sailmakers in Sweden for my J/92. I’ve just received the design proposal and I’ll attach a few screenshots from the SailPack file.

Honestly, I don’t know enough about sail design to judge whether anything looks right or wrong.

My current main is a North 3DL from 2012, and it has developed quite a “beer belly” over the years. I’ve also struggled with mast bend / luff curve and some fullness/wrinkles along the luff area.

One important thing: the previous owner apparently cut about 5 cm out of the luff curve of the old main to reduce draft/fullness. So I’m a bit worried about getting the mast bend / luff curve wrong on the new sail.

The new sail is planned as:

X-Drive Carbon, grey 160 with taffeta
4 full battens / performance battens
2 reefs
stack pack, since the sail will stay on the boat for the season
used for club racing, a few bigger races, and cruising/family sailing

What should I be looking for before approving it?

Main questions:

Does the luff curve / mast bend assumption look reasonable for a J/92?
Given that the old main had 5 cm removed from the luff curve, what should I ask the loft to check?
Any concerns with the roach, batten positions or reef positions?
Anything specific to J/92 mainsails that I should ask the loft to confirm?
Any common mistakes with new J/92 mains that I should avoid?

I’m not trying to second-guess the sailmaker. I just want to ask the right questions before the sail is built.

Thanks!

Hi,

I have J/92 #9 and all I can say is that UK Sailmakers Northeast, here in the US, made me a beautiful main because they know the boat really well and that's the reason I chose them. I don't know anything about UK Sweden or if they would collaborate with other UK lofts.
