I think maybe a balsa model before I rebuild a boat? The stuff that needs testing is reefing/the mast rings. Building a section to scale would confirm the mechanisms. The math on a foil isn't really a worry. Also I really don't want a boat in Seward. 1 more summer then I'm moving someplace that...

Yeah. Ideally. I might have to use a cart til I move. The water here in Alaska is very cold, and currently frozen. Though I guess this would work on an ice boat test platform

Working on it. Not my strong suit. The only novelty is shaped mast rings- and really the only issue I'd worry about yet is height to prevent jamming and still stacking well enough. The external batten is from aerojunk. Laced sail panels are easy to imagine? The reefing system just brings us...

I tried a simplified version. Thoughts?

I hadn't touched a laser since I was a kid. But, yeah, something a bit...more... in stitch n glue would be better. The laser came to mind as being sensitive to drive and heel and efficiency

..but the "designed for" issue seems like a side issue? The Junk was designed for shallow draft scows without keels in Asia. Modern junks are already quite different. The split and aero junks already have a lot to recommend them. The "slow junk" seems like it's historical, and a product of the...

Omg no. I was picturing aluminum pipe. Honestly an OZ Goose is probably a better platform. You're quite right, bending the core of the assembly like that would at best add a lot of potential complications, at least for testing

I think we are looking at different junk rigs? The AeroJunk solves a lot of this already. Also I think we are at cross purposes here. I'm interested in the rig- if the details can be hammered out it could be tested on an ebay laser to start

It doesn't seem like those assumptions are at all clear. "Things I belive make me think this is impossible" doesn't really help running numbers. Let's start with Twist control? Why is interior twist control plus traditional junk lines "necessary?"

Good finds both. Tystie's sail had what? A "too much hardware" problem? I hadn't seen it, but approaching the contruction from the "not too much hardware" aerojunk foundation might find a way around that? It seems like the principle is sound and the implementation is the question. We see the...

Hi, I've been a bit of a lurker, and haven't been sailing in years. But I was thinking of maybe building something small to get back into it. I think I prefer easy to exhilirating most of the time, so I've been looking at junk sails. The Aero and split junks caught my attention, but the aero...
