It’s easy to install. The standard forestay is replaced with the new stay which the jib is “permanently” attached to. So once you get the adjustment right the process for setting up the boat becomes a little bit quicker. The forestay and jib go up together.
There is a slight adjustment process you’ll go through the first couple times. You want the lower forestay attached pretty low to the bow deck strop. The instructions will give you the distance but I think it’s about 50mm. So to get that right you adjust the strop at the top of the forestay either shorter or longer. It might take you a couple times to get it the proper length. After that it may stretch a little and need to be further adjusted, but after that final adjustment you’re not likely to have to bother with it again.
For my money this is the best thing I’ve added to my Weta.
