eagleeyepandv	Posted - 10/18/2021 : 17:35:06 Does anyone know the height of the spreaders from the base of the mast?

Volksaholic	Posted - 10/29/2021 : 07:19:32 I've recently purchased an '81 tall rig and I've measured the spreaders to be about 15' from the mast head... pretty close to the mid point on the mast. As others have stated, we don't know how precise you need to be so I'll warn you that I was after ballpark measurements rather than precision. My mast is down so if you need a more precise measurement from a tall rig boat I can get it for you, just let me know. Paul in SLC, UT 1981 C25 TR/FK
Steve Milby	Posted - 10/20/2021 : 16:22:14 Many of our members have used a system like this to raise and lower their masts. This fellow even uses it to lower his mast while underway, to pass through a low bridge. Plans for it can be found in our Tech Tips. https://www.youtube.com/watch?v=r33VCObNroY&t=2s
Voyager	Posted - 10/20/2021 : 15:59:41 Wow! There�s always another way to skin a cat. From what I saw in the video is the A-frame needs to put the hoisting strap at the mid-point or balance-point of the mast. The question I have is: how do you ensure that the strap stays put on the mast and doesn�t slip? Apparently it sits just below the spreaders. If, however, the mast begins to invert slightly, it�s possible that the strap will slip and capsize the mast. I also felt badly for the lady whose job it was to lift the mast out of the tabernacle. It seemed heavy and slightly unstable. I assumed that the A-frame was stabilized by a forestay and a backstay tied to the chainplates?
eagleeyepandv	Posted - 10/20/2021 : 15:18:48 I'm using the technique described in the video pasted below to take down the mast. If you watch the video you'll see why I need to know the spreader height. https://www.youtube.com/watch?v=vpFhnYQmRYs&t=83s&ab_channel=LeeScott
Stinkpotter	Posted - 10/20/2021 : 13:43:02 Just curious... How precise do you need to be? (You never mentioned why you were asking.) Measuring on a photo of my SR taken from a distance, they appear to be just about precisely half-way up from the cabintop. So 14' is probably well inside of a foot from the actual.
dmpilc	Posted - 10/19/2021 : 19:10:02 Tying a tape measure to a Halyard and raising it to the spreader should give you a fairly accurate measurement.
eagleeyepandv	Posted - 10/19/2021 : 17:19:06 All good suggestions. At one point, I attached my tape measure to the main halyard and ran it up to the spreaders. Unfortunately, I cannot recall the measurement. Since the mast is 28' (I think), is it a safe assumption that the spreaders are close to half way up the mast, making the spreaders' height about 14'? This seems to be close to Voyager's guess.
glivs	Posted - 10/19/2021 : 16:19:01 Depends on your requirements but a thought....I've recently had good use of an app on my iPhone (2-3 generations old) that measures distances using a light pointer to mark the end points of the distance to be measured. Works rather well within a limited range if not too much external light interference.
Voyager	Posted - 10/19/2021 : 16:12:24 Yes, I inspected the �Manuals and Brochures� section at the left of the Forum pages, but did not see any dimensions written on the charts.I reckon that it�s about 12 ft to mine (I used my extension ladder to reach) and that�s what I recall�
islander	Posted - 10/19/2021 : 12:38:06 Toss a ball of string or line up and over the spreader then pull both ends down to the base. Mark the line then pull the line down and divide the length in half.
eagleeyepandv	Posted - 10/19/2021 : 10:51:53 Good point! It's a standard rig. Thank you!
Steve Milby	Posted - 10/18/2021 : 17:54:48 Someone can probably measure it but they need to know whether you have a tall or standard rig, eagleeye. Create a "signature" for yourself similar to this: "1985 C25 SR/FK." It will give folks the basic info they'll need to answer most questions.
