[C38] Navtec Service locations

Mon Aug 16 18:40:10 EDT 2010

Joe,  I believe we are talking about to different companies here- Navtec and Sailtech in Oshkosh, Wisconsin.  On mine, a Sailtech, there is no way the seals come in contact with the threaded portion of the shaft.  To remove the unit you just remove two pins, one at the top and one at the bottom.  From what I'm reading I would stay from a Navtec design if I were buying a new one- hard to remove and leaks, etc.
Cheers, Steve O

Steve,
    I'm sure it was this thread that caused my backstay adjuser to leak today for the first time in 18 years. It is a Navtec which I am afraid is Lewmar - does anyone have any idea where I can get this overhauled in southern calif? Santa Barbara is great for olives but short  on technical support. Joe

Santa Susanna (1985) has a SAILTEC hydraulic/mechanical locking backstay adjuster.  You hydraulically apply the load, lock the adjuster and then remove the hydraulic pressure- no pressure, no leakage.  About 10 years ago, I left the pressure for several days, maybe a week, on by accident, and blew the seals.  I sent back to the manufacturer for over haul and it cost around $400.  Since, using it properly, I've had no problem.  I'm sure the secret is the mechanical lock.

The problem for us in discussing backstay adjusters is that Catalina used a variety of them over the years.  The first one was a Navtec -35, which as produced in the late 70s and early 80s.  This one is tough to re-build and about 10-20% of them leak even after a rebuild.  The 35 model has a nickle sized plug on the bottom that is at about a 5-10 degree angle from the bottom face.   
This unit was replaced with the -36 model in which the plug is flush with the bottom plate.  the -36 model is more reliable and there appears to be no trouble rebuilding them.

One thing to watch out for is our old problem with stainless and corrosion!  About one in ten -35 and -36 models need a new stainless rod, which really ups the cost.  Normal rebuild cost by the way runs $300 - $400 according to the shop I use which used to be called Marblehead Marine:  ( http://www.theforepeak.com/     (talk to Tom)).  By the way, the shop won't know if your is a "leaker" until after they have spent all the time and materials.....  

Defender.com sells new ones for $1200.   At this time, mine is leaking as well and I have not decided whether it is worth it to rebuild....

Dear Group: I have a Navtec hydraulic, with a gauge, that will put huge pressure on the rig with great results for head sail shape. However, it leaks hydraulic fluid and is constantly making a mess. Expensive repair efforts, including expensive shipping, have failed to stop the leaking. A mechanical BSA, one of the chrome wheel types, looks attractive. Problem is, it seems to me, that one would not know how much tension is placed on the rig.
What are the experiences of others of you?

Hey Bill , 

Congrats!
I also planning to install a backstay adjuster on Estancia, but still not sure if I should go for a hydraulic or a mechanical......
I'm also going to race tomorrow. Just borrowed a huge 155% and a huge assy, so we'll see how it goes.....

Hi everybody!  Just thought I would let ya'll know that Zephyr was entered in another regatta here in St. Andrews Bay (Panama City, FL) and kicked butt once more.  The second place boat crossed the finish line more than 7 minutes later.  

We have a new custom fitted mainsail on now.  Next on the list to be done will be an adjustable backstay.  By this fall we will hopefully have a new 155 installed.  

Right now we are in the non-spinnaker class.  By next year we hope to be prepared to be in with the spinnaker class.  We are having lots of fun on this boat.
