The clever arrangement of the rollers with the large axle, through which the rope can be threaded either from one side or the other, allows clean rope guidance for sails with three rollers. Both for the roller block as with GunSails - and for the variant rotated by 90 degrees in comparison.
The soft, smooth Dyneema rope supplied noticeably reduces friction and trimming forces, but - like all Dyneema ropes - it also tends to pinch your fingers when pulled hard. A loop and the harness hook are therefore ideal for fine trimming.
With a shortest length of just under 2.5 centimetres, the extension should fit most sails, the adjustment ring can be moved quickly and securely (open and twist slightly, then it goes from zero to 48 without stopping) and snaps into the holes automatically. The push button is quite small and tightly sprung, but sits elegantly and flush in the tube and is easy to operate.
