    Existing rig has in line spreaders and runner back stays . I want to change this setup to swept back spreaders and do away with runners . The existing bulkhead has some rot and needs to be replaced . I can only move the bulkhead aft 25 cm because of engine mounting in the way . But how do I calculate the angle and length of the spreaders . Any help is most appriciated .

    Thanks Kevin

    If the runners are needed to keep the rig up, 25 cm won't allow enough sweep to eliminate them. You'll need at least 15 degrees and 20 would be better.
