The 5.2 has no effective way of keeping the rudders in the up position(at least not with the bungeesystem), so off they go! Its safer for the boards anyway
For this problem I take the jib sheet and tie a slip knot. I wrap this around a rudder so high it cannot slip down and pull tight to the rear beam, I go across to the mast and tie it down to beam and then to other side of beam and out to rudder.
This keeps the rudders up and the mast down. I then pull a bright flag into each of the knots at the top of the rudders.
