Subject: Measured Angles
In reply to: Gitano 's message, "Spreader Angles" on - Monday - 09/ 8/08 - 11:31am

I did measure the spreader angles. I used a little clear plastic angle measure doo-dad that I got at the hardware store a while back. Here's what I came up with:

Starboard side:
Angle between mast and spreader above spreader: 82
Angle between mast and spreader below spreader: 99
Angle between shroud and spreader above spreader: 83
Angle between shroud and spreader below spreader: 84
Shroud angle around end of spreader: 167

Port Side:
Angle between mast and spreader above spreader: 83
Angle between mast and spreader below spreader: 98
Angle between shroud and spreader above spreader: 82.5
Angle between shroud and spreader below spreader: 85.5
Shroud angle around end of spreader: 167

Looking at these numbers, it's clear that my measurements are not 100% accurate. For instance the angles above and below the spreaders along the mast should add up to 180 but they actually add up to 181. The other thing that you might notice is that my spreaders don't perfectly bisect the shroud angle (particularly on the port side - I'll have to get up there and make another adjustment). At any rate, I think the correct spreader angle (between mast and spreader, above the spreader) would be 83.5 degrees (plus or minus 1 degree).

Let me know if you have any questions.

Wow! thank you very much. Would it be possible to also measure the distance between the main spreaders and coach house roof? (how high up the main mast are the spreaders located?)
