What kind of nut?
I agree with all that the other guys say. It just depends on what kind of nut you are ... If you are going to weather in 35-40 knots, the cutter rig with running backstays is a big plus.At this point you'll probably be flying just the staysail and maybe two reefs in the main. The mast will tell you to put on the windward backstay: you'll see it pumping a bit above the spreaders in the gusts or in a seaway. Just clip it on the toe rail where you can get at the tail of the purchase to be able to uncleat it from the cockpit. That way, before you tack, you can easily release it. Make sure you have lots of rope on the purchase to let it go slack enough to not interfere with the main when it comes across. Now you set up the other (new windward) runner and off you go. Of course, in this kind of weather, you have lots of searoom, right? Otherwise you'd be tucked in the nearest hidey-hole, drinking rum, right? So, it just depends on what kind of nut you are. (Last sunday I was setting up the runners in 30 - 35 k. and NOT drinking rum - What kind of Nut?)
