Hi,
I was wondereing if someone could explain to me the procedure to measure the angle of rake swept back spreaders have on a sailboat? I've looked all over and can't find the information and Jensen is long out of business. I have a fractional rig with the swept back spreaders. Any simple explanations or ideas on how to do this? Thanks, Mike |

I cannot imagine why anyone would want to know the sweep angle but.....If
you measure up the stays from the deck high enough to clear the house (if there is one) and place a piece of tape. Measure from one spreader to the other at the tape elevation. Then measure horizontally from the tape to the mast. These figures define an isosceles triangle. Solve for the base angle and that is the sweep angle. Sweep angle equals ....the angle whose cosine is half the width measurement divided by the mast-to-stay measurement. |
