Bo - looks like a nice (but cold) part of the world
I would be keen to explore your waterways in high summer
I don't know what your current rudder arrangement is but I guess there must have been a reason for the current ( interim) upgrade.
I am not that happy with it but know that I can rely on it providing I lock it down and use the bungee. I am not prepared to take any chance of losing control
Like everyone, I am really looking forward to the new rudder, however we don't know when we are going to get it. Matt Miller did indicate that if all testing went well, we could expect them this April/ May.
I think there is a fair chance we may see this blow out - possibly until after the new model year ( August).
If it was me, would do the upgrade.
Do you have any AI/ TI buddies you can sail with?
