Ours is quick at hand, but....I have always wondered if it is necessary . Our boat has a ring/pinion steering setup with a link bar to the steering arm. A pretty solid setup, so the question is... What is likely to break - linkage, shaft? Would appreciate your views .
We had just departed Norfolk for the Virgin Islands 3 years ago, and our steering “went out” before we even got out of the Chesapeake! We placed a “Pan Pan” and alerted the USCG of our situation, as we started dropping sails, unpacking the anchor, unpacking the ET, dropping anchor, and diagnosing the problem. Actually, deploying the ET was instrumental in diagnosing the problem - hooking it up showed us that we still had a rudder, and that our quadrant and cabling were all still intact. Eventually, we traced the problem to a loose set screw that allowed a key to slide in a keyway on a steering shaft behind a bulkhead in the engine room. Slide key back into the sprocket and, voila! - we have steering again. Took only 5 hours to find it and get back underway...
We learned some lessons from this exercise: first, it’s a good idea to actually install and test your ET, as previous posters commented, to make sure you have all the parts and know how to do it, and to find out what else you need to then actually steer the boat with the ET, such as blocks, lines, etc. to use for leverage and to secure it in place. It also helped us realize we really didn’t want to have to steer an 80,000# vessel very far with an ET! Blocks to each Genoa winch were in order. Next, that you really do need to know all the parts of your steering system, from wheel to rudder, and autopilot, and inspect and lubricate the parts that need it.
It’s good to know that you can use it if you need it, and how to service it so you, hopefully, never have to use it!
