As an old-fashioned guy, I use a topping lift set up to do this job... if I understood Your point correctly...

Lykke, while single-line worked well on my trailer boats, I’ve separated the tack and clew reefing lines on the ocean boat. Three little dyneema lines, one tied to each tack cringle, led through shared low friction rings, to a cleat next to main halyard winch. Start the reef by easing the halyard, pulling/winching appropriate tack down line. That’s just a few seconds and made fast. Now I can take in the clew as easily as single-line reefing but it’s not fighting / competing with the tack. The sail is momentarily depowered as the halyard as the tack/luff is coming down, and the winching on the clew goes much better than when it’s also including the tack portion. It’s working really well for singlehanding. Just a little devils-advocate there for you
Perhaps it got lost among all of the proa spam… the issue is to reef downwind after falling off too much as an easier way of dealing with “puffs” (=wind increasing).
With your system, just fixing the tack first and leaving the clew loose you turn the mainsail into a kite pressed against the shrouds. Very problematic.
Reefing downwind effectively means turning the leach into a luff and trying to “leach” the sail to de-power it. Very hard, I found impossible in >20kt. This means reefing the clew first.

Downwind reefing is not pretty, but very achievable...
Good sail design to start with really helps. A slide or a batten right on the reef or a tiny bit above allow you to do as per Lykke sails are reef semi clew first. Without that slide or batten you risk loading the sail up to the next slide or batten, which will most likely not be strong enough longer term.

I've never been a big fan of single line reefing. It's "easy" but doesn't give you a lot of control.
With separate tack and clew lines you have the option of pulling the clew in first, raising the end of the boom. You can then ease the halyard and use the mainsheet (combined with the tack) to pull the sail down.

Topping lift. There’s a reefing checklist made with label maker pasted under the dodger, by the clutches. #1 is Snug or deploy Topping Lift! Because of course I didn’t once and dropped the boom, causing a hardtop repaint

Agreed. I’ve reefed clew first, and sometimes alternating. Mine’s probably more forgiving bc of inducing a lot of mast rotation and the sail isn’t hitting the cap shroud. But I really appreciate the flexibility and speed of the tack and clew being separate control lines.

We have a system that BoardHead suggested and did a drawing for us. It uses the jiffy lines to hold the boom up and it's the 'trimarans paws'Topping lift.

Hold the boom with lazy jacks if its a square top or roachy sail as the topping lift wont always be windard side.
Lazy jacks I don't have a topping lift. Clew first and bring the traveller inboard. I have reef hooks and they are excellent. Set them up at the beginning of the season for trouble free reefing. With single line the tack ends up massively loaded when trying to get the clew in.

Now you are are just talking utter crap....How can anything made from mixed, unclean waste have repeatable mechanical properties...?The other grants have realistic time scales which we should also be able to meet. My willingness to put up the time and money to get a prototype built made a big impression on the UNDP and other organisations. We are adopting a similar process with the other grants:
The plastic recycling application was ho hum until we showed them a metre/40" long section of 60mm/2.3" dia rod made from mixed, uncleaned waste with repeatable mechanical properties. Everyone sat up and asked how much money do we need, when will we be in production and what will we use when all Fiji's waste plastic is recycled?

I use tons of recycled plastics each day..... a PET bottle or PP/PE cap is very different to GPPS cup.... it will fail and cause delamination....
Just finish the cargo proa and prove us all wrong.... one thing at a time

I can't discuss details until the grant is settled, but everyone from the Ministers of the Environment (Fiji and Aus), the 2nd in charge of the UNDP ($US5.6 bn in revenue last year) in the Pacific down to a couple of 10 y.o. kids in a remote village that has seen the samples thinks it is the solution to the plastic waste problem and are doing everything they can to make it happen.
I will pass on your concerns.
I will probably forget, so ask me in 6 months and I will explain it. Or follow the cargo proa updates on http://harryproa.com/?p=3788
It is great working in a place where the response from the funding agencies, locals and Govt is 'Wow, great idea, let's make it happen' rather than "utter crap. I know everything about this subject and I can't understand it, therefore it's impossible".
FWIW, my interest is in making cheaper, faster, easier, safer boats and doing what I can to clean things up. I have no interest in "proving all of you wrong". Nobody who matters is at all worried about the pace of progress. They are impressed at how quickly it is happening and see the other projects as a bonus.

Funny, you had a decades long interest in proving me wrong. Have you changed?

correct and literally 100's of posts here and everywhere justifying what he does to prove him right.
