In order to avoid zoning issues at the boat shop I ran everything off
two 100 foot, 12 gauge extension cords. They ran everything I threw at
them including my Table Saw and Radial Arm. I had them each plugged into
dedicated lines from the fuse box. Never noticed any problem with them
and any loss of power at the plug.

I used to have a 250 ft 10 gauge extension cord that I built myself
from a roll of 12/3 romex cable. It was stored on a garden hose reel
for ease of deployment and to avoid kinking. It was very useful in
winter storage boatyards where the boat ended up being a long way from
an outlet box. I could run electric heaters and any power tool that I
wanted from it.
Yeah, growing up my dad had two 10 guage 50 footers and they are still
here but at over 60 years old last time I went to use one, I got hit
because of old insulation so I kinda' hung 'em on the wall and moved on
