I’ve heard so many bad stories about hydraulic backstay adjusters that I don’t doubt them. Having said that I never had a problem with one on three boats over 15 years. Certainly not the type of failure you’re referring to.
Without a split backstay your options are limited. Personally I consider the mechanical adjusters to be worthless. Just too slow and not enough power… and a nuisance as others mentioned. You could go very old school and try very beefy blocks led to a dedicated winch but that has its own set of problems and cost. Short of that, its hydraulic - either self contained units or components which are even more expensive. I can’t say I’ve heard much difference from brand N to S. After 25 years you may want to cut the Navtec unit a little slack. A new unit is probably your best option. Of course, you could say the hell with it a just put a turnbuckle in. Depends how you use the boat. John On Oct 8, 2014, at 5:32 PM, Tim Goodyear via CnC-List <cnc-list@cnc-list.com> wrote: > Bruno, > > Have you considered a cascade system?
