Navtec Hydraulics

Morgan’s Cloud was fitted with an hydraulic vang and with hydraulic backstays when we bought her. Initially we were skeptical, feeling that such complexity had no place on a cruising boat, especially one that sails to remote places.

But over the years we have come to appreciate the convenience and ease of use of our Navtec hydraulic rigging system with its cockpit mounted control panel.

We do believe that a key requirement for reliability with these systems is getting them serviced regularly by someone who really knows what they are doing. Jay Maloney of Maloney Marine Rigging gives our system a good going over every five years.

John, In wandering around old threads, I came across your Navtec comments. We shared your concerns for the similar reasons. Three suggestions: I determined that our Series 7 default length would be too long to have adequate backstay tension even if the turnbuckle was tightened all the way. We had stainless straps made so that the hydrolic backstay (HBS) could be taken out of the rigging completely and sized so the backstay could be tensioned by the turnbuckle. This allowed the rigging to be viable in the event of an offshore HBS failure or for a period where the HBS were away for repair. The straps were quite reasonably made in Turkey, much cheaper than a piece of wire that might substitute. We also made a simple Sunbrella cover for the exposed ram and seal to keep off the dirty rain that exist in many areas. The last thing we do is, after relaxing the rig, to put in a few pumps of tension. This keeps the seals always under some pressure from one direction and mitigates “panting” which occurs with atmospheric pressure changes. The latter two suggestions I have no clear idea about how effective they are, but they make me feel better. Dick Stevenson, s/v Alchemy, Dublin, Republic of Ireland

To my surprise I have just been loaned a spare Navtec ram to see if it will fit. It has a pump and a panel with provision for a backstay ram as well, so I seem to have started down a route that I wasn’t expecting to travel, due to budget limits. Another length of learning curve opens up… if I didn’t know that Morgan’s Cloud has this equipment I would have spurned it as racing gadgetry.
