 Additionally if there is no mainsail there is difficulty in heaving to or coming to rest with sails set and boat "weathercocked" with bows into the wind.This can make the boat much more vulnerable in storms when a partly furled foresail has exactly the wrong effect on boat position relative to wind and waves while hove-to and this, though less of an issue for racing, is still an issue for long-distance cruising.The performance of the sail is dependent on having a forestay which is taut.
