Telescopic masts?

And then there is the stability in wind formula which Valhalla is referring to. JS really discusses all of this in detail.

If you are just worried about righting moment, much simpler to reef the sails, rather than build a telescoping mast.

Hi All!

Interesting topic, something I've also thought about. Wondering if there's been any more discussion on telescoping masts?

I can't seem to reach anyone at this company, but it sounds like they were considering testing TV truck antenna masts for their inflatable wing sails: Inflated Wing Sails | concept

Thoughts?

I read through this thread, seems the original topic went to the wayside...

I tried reaching out to these people too. They don’t appear to want to sell anything.

But I’m extremely interested in figuring out a good way to handle taking the mast down without a crane.

Mine had a forestay and two shrouds. One on each hull. 3 stays. Fractional rig. That’s how it is designed but I haven’t got a rig on yet. 60’ -64’ mast section, stepped on deck, about 6’ above the waterline so 66-70ft bridge clearance. Not ideal.

Would love to find a rig that I can lower.

The mast on my 11' Edey & Duff Columbia Dinghy is two sections, connected by a sliding coupling, w/ an angled joint.

The disassembly permits storage of both mast sections when not in use in a long bag, w/ the boom, having the sail wrapped around the boom. That sail rigging bag fits nicely into the dinghy for storage.
