I figure that with the 'tree stump' of a mast on the 30-1, I should be OK. I have done it a couple of times when the wind is up (rare, around here) and used the working jib. No problem.

It could also apply to mast head rigs without back stays.< What Fred said matches my understanding of why there may be some concern expressed by some sailors regarding sailing with head sails only. In the very old days the ship’s rudders were so small and weak balancing and steering the vessel by the location and trim of the sails was necessary. Modern designs and construction methods allow us to compensate for an un-balanced rig with mechanical advantage and a strong rudder. During the heyday of IOR designs, including fractional rigs, many designers and owners in search of the smallest advantage would put up a lightly built small section mast. I recall seeing 4 and 5 spreader rigs on 40’ boats with very small section mast extrusions. Many of these rigs appreciated the additional fore and aft stabilization that the mainsail gave to the mast itself. Many of these rigs went over the side owing to operator error. For those of us sailing a well maintained non-custom (thinking Evergreen here) C&C design with the headsail only in most conditions but certainly in light air will not jeopardize the rig’s stability. If you find yourself in heavy air “pounding” conditions it may be well to sight up the mast as the boat makes a hard landing to be sure the mast “pumping” (fore and aft”) is under control. In those extreme conditions some mainsail load may add some dampening to the mast pumping.

Unfurled the jib in 10 knots of wind and decided I was too lazy to remove the main cover and hoist the main. I've read that sailing under only jib is bad because it places an uneven load on the rigging. Seems to me that the load is minimal in light air and the total load is a lot less under one sail. Thoughts?
