When we bought our boat it had an old Hyde Streamstay, behind the mast furling main system. It self destructed by the time we got to the VI so I ordered a new main from Doyle in St. Thomas. I wanted full battens but then I was told I needed at least 'Sailtrack ' and was running out of money so I ordered partials.
Mistake,,,, I should have just spent the money and got the main i felt was right for the boat.. We sailed another 25,000 and 10 years with a main I was unhappy with.
