No experience with it yet. Hoisted our Maxx cloth sail first time on friday, but still have to install grommets for the battens, stretch and secure the bolt-rope and some other small stuff. If we can use it the coming week, I'll be pleased.
Marcus: I'll send you some photos once it's finished.
We used 25mm overlap between panels (cross cut layout), 25mm 3M special basting tape/glue for laminate construction and two rows of three stage zig-zag stitching. We also double folded all hems, and did some special reinforcing at the luff to take downhaul loads. Batten pockets are installed with 25mm glue and a single zig-zag seam over the panel seams (not optimum placement, but close enough for this try).
We hope this will be enough to hold the panels in position, but time will show.. I'll be sure to let you know if we have catastrophic results.
Macca have some practical experience with his Maxx sails now, so perhaps he could say something about it. Looking at the pictures he posted earlier in the 5.7 thread, it seems like they did a sandwich construction at panel seams integrating batten pockets, and further sandwiching at reinforcements etc. Interestingly enough, the reinforcement along the luff seem to be glued on..
