List your requirements for a replacement mainsail here...

Fully battened
3 reefing points
Top few feet in bright orange or covered in reflective material
Ballbearing battcar system
V strong reefing points with some way to minimize chafe
Simple way to lash the 'spare' sail when reefing: most seem to have only v.small eyes - surely there's a better way?
Lots of telltales, not just on the leech
Telltales away from the batten pockets then they don't snag on the velcro.
Heavily re-inforced batten pocket ends.
Sailcloth that is known to hold shape over the years and that is proven to last. Someone else can take the risks on the latest and greatest.
Sailcloth with mildew protection/treatment.
UV protected thread.
Decent sized spreader patches (perhaps these could be in reflective material too).
Leech line tensioning system that sufficently grips the line and is easy to adjust- how many times have you known them to slip?
Leech line adjustment when the sail is reefed.
 
Decent sailcloth
Flat cut
Loose foot
Over the top leach line
Depending on size of the sail, blocks instead of leach reef cringles.
 
Out of interest, why no full battens? I wouldn't go back to non FB for a cruising boat.
Very different on a race boat of course.
 
It'd would depend on what sort of cruising I was going to do. Coastal/europe/Med I'd probably go FB, but not for crossing oceans. The extra weight slapping around aloft in light conditions on a proper swell throws all the air out of the sail and puts horrible strains on your rig.

Although with the boat I have now, FB are not really an option at all.
 
Hi Sir
It really is a personal thing I suppose, I sailed for many years with "normal sails".. I like the luffing feedback and general feedback from a non fb sail.. we went for fb due to a desire to refit the old round the boom roller furling / reefing, to allow a better shape to be maintained to the boom on rolling.

I sometimes like to use the main as a steady boy steady lol, some call it "Solent Rig" whilst motoring in contrary seas..

the FB system just does not give me the feed back I am used to / like / need ? ... as said, a personal thing really.

for my type of sailing / cruising / liveaboard use, absolute shape is not necessary. feedback is.. and its more to go wrong, having had broken baton ends, ball track car faults etc.

Just seems like another gizmo, I would happlily dump the FB overboard, however, for around the boom furling it is a godsend, so, I will stick with it.. the main is a small percentage of our drive anyway.. we tend NEVER to reef the main, seriosuly.. we just dump it n go Jib n Jigger or Stays'l n Jigger..

the only real benefit I can see is the ability to cut a wider roach, but my back stays, mizzen fores etc negate that really, and the topping lift chaff can be a right royal Price Charles Dog Face Camilla pain in the arrrze...

But, to be fair to everybody, we have the better rig /forums/images/graemlins/wink.gif /forums/images/graemlins/blush.gif

a Ketch, much underated, much misunderstood, much flexibility though, and I wouldnt have it any other way.

I went for fully battened having experienced it on friends boats.For me the big advantage is no slapping if motor sailing,which was a boon when we had to motor sail most of the way to Holland this year.Combined with a lazy jack zip up bag it suits me.Most of the other points have been covered.
