For those interested in 505 mainsail shape ...
We took photos of mast bend and resulting mainsail shape, using three different mainsails, over three days. Conditions were fairly similar all three days.
We would set up the mast using the ram, take an image or two to show the mast bend, then take images of the resulting mainsail shape. The photos of Devlin are to break this up into related images. The batch after a Devlin image would be after we changed mast bend using the ram, or changed the vang setting, and looked at the resulting mainsail shape.
The first set of images (August 9th) is of the KSL prototype 505 main. It has the black 505 Insignia, blue CAN 8841, and a black luff tape. It has a triradial panel layout.
The second set (August 12) is using a somewhat tired North M-10T. Blue 505 Insignia, blue CAN 8841. Panels radiate from the head and the clew.
The last set (August 13) is of the P&B standard (not flat) main, which is rather newer and lower mileage than the North.
