Thanks to GordMay for the links and to SkiprJohn for the confirmation. It appears that my mast is 40-ft long with single
spreaders at 20-ft. With the winches installed, the sum will probably approach SkipMac's estimate.
I have built a trailer
for hauling the mast with my Elantra and was a little concerned about the weight center of gravity being higher than the trailer
floor. 10-ft of the mast will extend over the car. I was hoping the total weight would be under 300-lbs for road stability. The bottom of the mast will be at the back end of the trailer (legal 3-ft hangover with red flag).
The trailer will also be the mast storage
and mast inspection
location with block supports to set the mast straight during storage
Thanks again for your feed-back.
