(Found) Solar sail space ship is a monastery and lightbulb factory (twitter req)

Here's a challenge for you, I saw this on twitter

"Twitter scifi mind, once again my google-fu fails me. Help!

Trying to identify a scifi novel

At one point the protagonist is on a solar sail spaceship. The ship is a space-going monastery. They make money by constructing light-bulbs, filling them with the holy vacuum of space."

Maybe we can help Winchell out.

In a later reply he adds:

"This was a novel I read back in the 1970's. The protagonist was only there for a chapter or so. He was on the run, and was hiding out in the monk ship"

"...the Holy vacuum of space!" ROFL

No mention of how it ships the light bulbs back ? Or are they planning to market them when the get to Alpha Centauri?
I don't think 'tacking' works with a solar sail

Sounds a bit like The Centauri Device by M. John Harrison.

Well the twitterverse is vast and someone has already posted the answer on the twitter thread. I expected it to take a lot longer!

Wrapping it in spoiler tags since I posed this as a challenge:
"Destiny's Orbit" by David Grinnel

Has it been confirmed that the answer on twitter is correct?
I remember (fair enough a long time ago) reading that book, but IIRC the plot doesn't tie in with the description in your original question

 

[tachyon]

Confirmed, yes. He did say the monk ship was only a brief stopover for the protagonist.

That's the first time I've come across ispoilers. Useful to know.
