Hello All,
Went out for a cruise this afternoon with the E38. Driving upwind/closehauled with 150% Genoa all the way out and full battened main in 16-17kts of wind. I went forward to check out the mast tuning and here is what I found:
Very slight leeward bend in mast on both tacks. Slight backward/forward motion of the mast at times, rhythmic motion, between fully straight and slightly bent aft.
I have checked the rig before and never noticed this. I was out for an informal race this weekend and it was blowing 25+kts. Had the big Genoa out and beat on the rig pretty hard before calling it quits after the first leg of the race. (Didn't think it was worth beating up my gear/boat) I am concerned that maybe I tweaked the shrouds?
So what do I tighten to straighten the rig? The cap shrouds? The lowers are fine, not loose at all on the lee side when sailing. The cap shrouds and the inners are both a little loose on the lee.
I am assuming the rhythmic motion in the mast is "pumping"? I tightened the backstay from 1700 to 2000lbs and the pumping appeard to go away. Then I noticed the Navtec hydraulic backstay adjuster was leaking oil from the piston/rod..... Great, another thing to fix!
Thanks, RT
