206BIII on Fixed Float Q's

I've been seriously considering building a Jetranger to be on fixed
floats to accomplish some stuff I cant do easily another way.

I've read through the ammendment to the Flight Manual for them, and
talked to some mechanics that worked on them, and I have a burning
question that's go/no go .

The FM has a warning about having the machine anchored/tied down during
run-up to prevent it from spinning. The trouble is that there would be
nobody available to release lines when I take off from a remote
location. Im sure as hell not gonna let a passenger (pilot or not)
do it either. I won't hot load/unload anyone whos not a chopper pilot.

Just how bad is this spinning? Is is possible to row the thing far
enough away from land to let it just spin around during startup?

The water is very flat where I intend to operate, and I could ususually
land on the leeward side of the islands to further reduce the wave
action and ensure that I dont drift ashore during runup/shutdown.
