I think that point is often lost in the process. It goes for almost any part of a boat that someone would consider to take that trip with.

It's a real hassle to deal with broken steering linkage, use an emergency tiller, all that, but it's not hard to design and build a rudder and post, that is strong enough to stay in one piece in almost any condition. People work with that all the time, and get to where they're going.

To break off in the middle of the new rudder(after the last one broke?), that's not a good piece of gear for their use. Head out again with another rudder? Maybe another boat,.....
