It turns out a couple of dock lines on the clew and a strope to hold the tack works fine. The jacklines held the bunt just fine. The thing to remember is that the forces on the cloth of a reefed sail are greater, but the force on the clew and tack are not much different than pressing hard before reefing. How could they be, since the boat is heeling about the same?

It looks calm, but I can tell you, it was not. Note the spray on the dodger.
