Paul, I am concerned that you are measuring from the masthead to the bowstrike instead of the mast height (vertically). The "I" dimension refers to the vertical dimension of the mast straight down from the top to the point where the mast intersects deck level (not the cabin top). This bottom point is difficult to locate as it hovers somewhere inside the cabin. If you check the original owner's manual (now accessable on the web site) and the Class By-Laws (also on the web site) you'll note that the official "I" measurement should be 41.25 feet or 41' 4". If you are coming up with a measurement of 41' 7" for this vertical dimension, I am concerned that you are actually too tall (??) As I have said before, (if you are measuring the distance from masthead to bowstrike and feel this is too short) it is quite possible that you are suffering from a combination of problems: your mast step could be soft (compressing) and lowering the base of the mast, your stringers could be weak-also allowing the mast step to sink, or your mast could be raked much further forward than recommended (which would result in a shorter measurement from masthead to bow). The last of these may have resulted from the furler installation - and the furler having been cut too short? As I said, you may be suffering from a combination of all these. There are just alot of variables that can affect the distance from masthead to bowstrike. The fact is, rig tuning for different wind conditions will cause this distance to vary even if the "I" is correct (only the most anal racers would go to this trouble). I'm beginning to think you really need to have a pro sailmaker or rigging specialist assist you in ascertaining your problem (if, indeed, you actually have one). Make sure you use a metal measuring tape when you measure. If, in fact, you end up being too short, the "I" dimension for the short rig should be 40' even. If you find this to be the case, it would merit a query of the factory to see if they have any record of the specific mast delivered on your hull. | ||

Please help with how you measure the I. I have and found that my hull 127 is 5 inches short.I used main and spi and genie halyards..I also have a Harken furler and a block 8 or 9 inches below the genie mast head block. This really gives me a pin to pin of 41' 7" My mast is straight with no bend Are any others short..... |
