Thanks David! My pipe search is on. is schedule 40, 2" galvanized water pipe heavy enough?
.

I am not even going to start on the math, but there will be considerable sway with 2" pipe. Schedule 80 would be better than 40 regardless of diameter.

You will have significant loading on these poles with a giant sail attached at the top of a 15'? pipe.

My gut tells me in a commercial setting this pipe would be spec'd at 6" schedule 80 or even 120 pipe.

70 degrees and sun, sausage is almost done, scrambling eggs next!

Morning all. At work again this morning. 0900, sunny, 80 with 90% humidity. Forecast high of 91 with 30% chance of rain. Had a nice thundershower yesterday, but only a tenth of an inch of rain.

Hazy, hot and humid. Looks like standard Was. DC weather has finally kicked in.

Inside again today, trim work. Almost done with this project.

Thanks Dean, I am taking your advice, my pipe will now be larger.

Had an early trip 85 miles up the road to pick up wheels and tires I bought for my Cutlass project, stopped at Cracker Barrel and had a breakfast to make Don cringe! No meat though, just scrambled eggs, biscuits, grits and sawmill gravy and some apple butter.

72F, .58 inches since midnight. Sun shining brightly

Apparently, I slept thru a 4.6 shaker this morning according to wife she and dogs felt it pretty good.

Off to Sunday breakfast
Have a great day

Another thought - My 4in pipes were required to be 1/3 buried in 12in of concrete. My 10ft high pipes are 5 ft deep. If that rule applies then a 21 ft would net 14ft. I didn't engineer mine, someone else, the architect, did.

Don, I would think the wind loading the sails would be minimized when set up horizontally, but if you mount them at an angle, you will get proportionately more loading. My J24 sailboat had a large sailplan and had a mast that was an aluminum extrusion oval shape with grooves in the front and back. I'd say the widest part of the oval was 5". But, the boat had cable stays supporting the mast and if you could do something like that, you could get by with smaller pipe. You could also attach the sails to the pipes with a "sacrificial" rope designed to break in a strong storm.

This could be a good thread on its own.
