In the past weeks I had the opportunity to test and compare the F-One SK8 850/xxxs monobloc stab 180 to the AFS Silk 850/stab 142. The SK8 was paired with a F-One 85cm HM mast and the Silk to a AFS 85cm UHM mast. Both foils have a medium high aspect ratio of 8 and were designed to excel in carving waves.
Finish is excellent for both brands with a shinier SK8. On the balance the Silk plane is the lightest with a weight of 1125gr and 1398gr for the SK8. The F-One mast is significantly lighter (1667gr) than the heavier AFS mast (2039gr) but the later is 2mm thinner on the 2/3 bottom half and much stiffer especially in torsion. Total weight for the complete F-One set up was 3082gr against 3194gr for the AFS.
