Any and all advice will be welcome since I,have never encountered anything like this before.
Thank's to all
Spreader tip "locks" are designed to hold the spreaders in position when to leeward and the yacht hard on the wind
, which tends to slacken the tension on the leeward shrouds as the windward shrouds stretch (somewhat) under loading. Initially, the caps should be left somewhat loose to allow the spreaders to be moved up or down as the rig is tuned so as to bisect the angle between the upper and lower portion of the shroud
and then locked in place. This is a somewhat iterative process and may take two or more trips up to the spreaders to get everything "just so". Racers are usually more dilligent about the process than cruisers as evidenced by the frequency with which one can observe spreaders akimbo and uneven on "cruising" or daysailed boats in marinas
compared with yachts commonly raced. A properly trimmed/tuned rig can make a significant difference in a yacht's performance so is no less important on a cruising yacht than a racing
yacht, particulalrly where passage
times are/can be extended.
