Hi All

i use and many others in the mossie fleet use 20 series blocks, Use Hi load blocks if possible.

I use the exact same as kingy exempt the one in the middle on the mast is 20 series. The cleats work fine. If not happy with cleats use different brand such as harken, Spin lock, riley, where some have metal s/s cleats and different designs.

I have been been using the ronstan RF5 for years using 8:1 in 30 knots.
If crew can't pull on rope make a handle at the end of the rope with a rubber tube with the rope through the tube
