I do not have an emergency tiller on Wild Wind IV. The USCG does not require a jury tiller on passenger vessels as long as there are two engines. If the steering would fail on a long trip it would keep you busy keeping the boat straight on the engines alone, but you would get to your destination. I steer with the engines alone in tight spaces for docking anyway. If you put a jury tiller on one side, and if the connection between the rudders is not other than hydraulic you would only steer one rudder. This would not be a problem as I proved on my last trip when I aligned the rudders and forgot to change the bypass valve back. If you had a steering failure and also lost an engine then it may be a problem. The rudder connection then could be critical depending on which side you put the tiller. If a jury tiller was fitted the rudder angle would not need to be large. As you can tell I have run these things through my mind and decided go without a jury tiller. I think it is a personal choice and how you feel about your own ability to fix things under way. Good luck Jean-Pierre, Dennis
