Double Spinn Sheets
We are about to launch a new 42 footer (new long keel wooden hull with high tech rig for cruising and IRC racing ... the 8m class). We are stepping up from much smaller boats but have raced for many years.
We are having a single double ended Spinn pole and two sets of sheets & guys. i.e. there will always be both a lazy sheet and a lazy guy attached.
This represents a hole in my experience that I need to fill! Why do I need two sets of sheets/guys? What sheet/guy clew/tack fittings do I need for this set up? (This is a unique boat that we are specifying ourselves, although faithful to the original design, albeit with the help of sparmakers, sailmakers etc ... not the designer who died in 1954!). Maybe I''m a bit thick, but I need some detailed coaching in setting up (and using) this double sheet system.
Could someone walk me through a jibe?!
