got some lowish power lines en route tomorrow and not finding a defintive height?
founds this - do we all agree this is correct? I take it, loaded/ballst in its not sifincantly less, say 6-8 inches??

A new mast is shown as 30 ft on BWY's web site, and it's supposed to be 2 ft longer than the (I'm pretty sure), so that also works out to 28 ft for the mast.
Yup, thats what I have. I have a bridge I can only clear at high tide so I measured mast top to the water with a string. For power lines watch for sag and if its close cross near the support tower.

HTH
I believe these figures are correct. The M has a 35' bridge clearance.
Also, if the power lines are in a tidal area, be sure to check the height of the tide when you go through. Bridge and power line clearances are shown on the charts at MHHW level (mean high high water), meaning that the charted clearance is typically the minimum clearance, except when the tide level is extremely high.

...and perform these calculations knowing that, if you screw up, you can kill yourself......
