Today, we installed a lazy jack system on a hunter 28 using Dyneema instead of double-braid polyester. We chose to used Dyneema because we wanted to minimize the clutter by using a 1/8 diameter as opposed to a larger double braid polyester. This keeps it more streamlined with less clutter on your boom.
The lazy jacks are cleated on the mast using a Harken cam cleat. We added cover to the Dyneema where the rope is engaged in the cleat. Retracting the lazy jack is easy. You just uncleat the lazy jack line, pull the lazy jack to the goose neck, and hook into a bungee. We simply just tied a stopper knot so that when the lazy jacks are retracted, they are in the right spot.
The advantage of using Dyneema is that it doesn't collect or show any dirt.
Using the 1/8 inch Dyneema is great because you can barely notice they are there.
Here are some photos to give you a visual of how the lazy jack system works.
