Alpha Ropes Skin Cover is a great way to match your choice of cores to a high grip but mid cost cover. It’s a blend of polyester and cordura, which places it tech and cost wise between all poly covers and something more exotic like Poly Tec or Maffioli KP cover. Handling wise it’s higher grip than either of those, but with lower heat and abrasion resistance.
I first tried this cover out two years to recover some Farr 40 jib sheets that had torn covers on winches. Last week I had the opportunity to inspect the sheets and they look brand new and still handle great. At $.89 per foot, this is actually cheaper than trying to use even a basic poly cover, so it’s a no brainer for recovering good cores with torn covers as well as building custom cordage.
Here is a set of simple Farr 40 jib sheets ( simple because they’re just tapered for the inhaulers as opposed to having a dyneema cover for the front 6′) and a set of tie-on J105 jib sheets. Both are over New England STS75 cores, and the 40 sheets are prestretched. This is an especially good fit for the 105 as they have worn Lewmar winches, so the extra grip is going to allow them use fewer wraps for quicker tacks.
