Gaff rig
[7] Gunter-rigged boats are similar, smaller vessels on which a spar (commonly, but incorrectly called the gaff) is raised until it is nearly vertical, parallel to the mast and close adjacent to it.In short-ended craft with full body, heavy displacement and moderate ballast ratio, it is difficult to set enough sail area in the Bermudan rig without a mast of excessive height and a centre of effort (CE) too high for the limited stability of the hull.[9] Whilst reaching, the CE being set further back, will encourage a small craft to bear up into the wind, i.e. strong weather helm.[citation needed] The usual adjustments to mast rake, or even bowsprit length may be made to a gaffer with persistent heavy weather (or lee) helm.Running goose winged with a balloon staysail poled out to windward will balance the CE; Nick Skeates circumnavigated Wylo II with this configuration.
