I sail on a Prindle 19 & would like to use a smaller main sail when soloing on days when wind is over 10mph. When raising the standard main the halyard ring hooks to a halyard ring fitting at the top of the mast where it takes the full load . I plan to raise the sail high enough using the standard halyard ring to be able to attach the foot to the boom & secure the halyard to a cleat at the base of the mast . Will the pressure from the halyard damage the mast head plastic shiv ? Will the pressure cause a problem to the mast. Please advise, Thanks, Bill
