I've bought a 2024 banzai 11 after sailing goya for many years. I can't hear any draft issues over the noise the by-ply window makes in choppy conditions.

. Also it is impossible ( not virtually either ) to rig and de rig without putting a crink in the by-ply window. ( no matter how many rigging tutorials you watch )
P.S Also if you don't roll the sail up the with the "tape" that runs the length of the leach ( obviously there to stiffen and stop the noise as a lot more of the sail twists off bringing the draft forward ) on the outside it delaminates.
It sails great when you get use to it ( just take some earmuffs with you )
Still prefer my older Guru's. I only wish I sailed the last version.
Disappointed but only at a durability level.
