sailorjohn Posted August 27, 2007 Report Share Posted August 27, 2007 I am a "NACRA NOVICE" and have only been out on my 5.0 on one occasion. The rudder lock down system fitted to my 5.0 has a substantial rubber ring fitted between the rudders & the cleat.This works really well as a hold down but has the problem of not kicking up when you hit a sand a bank risking substantial damage to the rudder system & ? transom. As most of my sailing will be on the Pumicestone passage where sandbanks are a fact of life, I have ordered the pivmatic system to allow the rudders to fully kick up without damage. It seems to be a great system, but I wonder if there are any shortcomings as the pressure to release the lock down cannot be adjusted. Will the pivmatic activate when not necessary such as if I hit one of those big blue jellyfish? I would certainly appreciate any advice on these rudder systems.. thanks John Link to comment Share on other sites More sharing options...
dood Posted August 27, 2007 Report Share Posted August 27, 2007 The answer to your problem is to not his sandbanks. Link to comment Share on other sites More sharing options...
CleverNickname Posted August 28, 2007 Report Share Posted August 28, 2007 John, I have recently replaced the pivmatics on my 4.5. I was having problems with the rope slipping through the cleats on the original pivmatics. I don't expect that you'll have any trouble with the jellyfish, it takes a good knock to make them release. I always release the rope before beaching to avoid unnecessary stress on the transom. Brad Link to comment Share on other sites More sharing options...
