Ah interesting thread. To be clear, I have zero experience with junk rigs. The closest I've come to sailing one is with my lateen rig on my portaboate, so not very close.
I love Annie Hill's approach to low-cost cruising. And as most know, she is a big fan of the junk rig. She claims it is much cheaper to maintain, and also describes how much easier it is to manage with a small crew. I assume she knows what she's talking about, but I have no direct experience.
As I mentioned in a previous thread, there is no realistic way for me to convert my
cutter into a junk. I think it would cost more than the
boat is likely worth at this point. Nor do I have any particular desire to do so. I like my
cutter just fine.
But if I was starting from scratch building a
new boat, I'd definitely
consider a junk rig. They're never going to be particularly efficient as upwind sailors, but neither is my
current boat

. The drive is simplicity and inexpensiveness.
