| Post subject: | How much should the mast twist ? |
Trying to figure out how much the mast should twist when sailing and if my shrouds need to be tighten or replaced ? I would say the track is pointed at least 45 degrees off the stern - so like over the back corner - depending if I'm port or starboard tack Shrouds def have some play in them when not under tension and could easily work the pin to the next hole - this would leave me with one pin hole left for adjustments for the shrouds - how soon should i be looking at getting new ones ? If I replace the shrouds - should i replace the forestay as well ? Thanks for any tips you can give |

The “twist” you’re talking about is usually referred to as mast rotation. A general rule of thumb would be for the centerline of the mast to point somewhere between the outboard end of the rear crossbar and the leeward shroud. Rig tension may affect mast rotation, but it’s really not the means of controlling mast rotation. Generally, your rig should be tensioned snug, so that the mast isn’t banging around, but not so tight that the mast can’t freely rotate from side to side. Note that when you pull in the mainsheet to sail upwind or on a beam reach, the mast will always bend somewhat, causing the leeward shroud to go slack. So rig tension really isn’t a factor a big factor in mast rotation unless it’s so tight that the mast can’t rotate downwind. The interval for replacing shrouds is really dependent on how often you sail and what types conditions. Around every 5 years would be a very general ruleof thumb. But that could depend on factors like if you sail in strong wind, sail in salt water, sail frequently, leave the boat rigged with the mast up for long periods, etc. Inspect the rigging at least at the beginning of the season. It is also a good idea to replace all of the standing rigging (wires) at the same time (shrouds, forestay, bridles). sm |
