Here's a sweet1998 Calvert on my H17. The sail was made for recreational sailing and not racing.

Let's try another shot

Sorry they're not very good, but here's one more.

Squaretop works fine on a boomless. I have one on my Mystere 4.3. If I remember from looking around for a friend, you should pay around $1300 for a good SuperR type squaretop, BUT boy are they worth it. Once you get one, you WON'T go back.

Waterbug, $1100 - $1400 is the range I've spent and been quoted in the past.

Material (cheap to exotic) and with or w/o battens and the Harken traveler will affect your final cost. Off season work can sometimes gain a few dollars of advantage.

I would still think a well designed pinhead would outperform a poorly designed ST.

I am curious if many of the sailmakers use software (if it exists) which can model mast, performance, fabric and wind characteristics into a cut pattern and then test the design in the real world? They would be worth a conversation.

Waterbug, I have a Sqaure top built by ullman sails for my 5.5 uni / Spinnaker rig. I The sail cost approx 1300 new with battens. It is two years old and I currently would part with it for 650.

Chackett, I may have an interest in it for my Uni. You open to a phone call? If so PM my email account.
