|jaroushey||This boat is my own design and is just under 30' with hard chines, 6' beam and 6' draft. Since the main is full batten and very full roach, runners are the only way of supporting the mast. I am thinking of having two attachment points on the mast leading to an equalizing block from that point it leads to a traveller car (fore and aft) about 3 or 4 feet from the stern. From each eye (fore and aft) on the traveller cars are control lines leading forward to a turning block and aft. There would be a stopper aft of the car to secure the tension and would be easily released. What do you think??|

Many "running backs" also incorporate one or two stages of checkstays and so would be impossible to tack without releasing one and setting the new one.
This is done during the tack - the runner that is on (to windward) is held as the tack is begun, then released as the boat goes thru head-to-wind. As the rig loads up on the new tack the (formerly leeward) runner is tensioned as required as the boat comes up to speed. The new "lazy" runner to leeward can be loosely set up on its winch or tackle ready to be tensioned on the next manuoever.
With today's large roach mains, even single part running backs can hang up the sail if both are left "on"
Downwind you need to keep an eye on the lazy runner so that it doesn't end up draped on the wrong side of the main, but handling them is similar - swap them mid-gybe. Forgetting to release a runner during a windy gybe can make life interesting.
Keep in mind that on many rigs runners may be more important when beating than running unless it's really honking out there. But it depends on the rig - some will fall down if the runners are mishandled.
Knowing what boat and the rest of the rig configuration would be helpful.

A thirty foot boat is rather small to have running backstays unless she is gaff rigged but the drill when jibing is to pull the main in flat and tighten up the new weather side then loosen the new leeward side and pay out the main. When tacking you can usually have both running backstays set up and just tack without touching them.
All the best,

tacking and jibing with running backstays
Please explain the process of accomplishing a jibe or tack with running backstays on, lets say a 30 foot boat with a crew of 2.
