Thanks for this, sorry if I wasn't clear.

The boat is steel so a short copper strap from the tuner to the hull is
easy. However, it's harder to do the same to the M700 neatly. Everybody
stresses the impoprtance of a wide strap to the tuner but rarely mention
the radio itself, those that do say it is 'good practice' to connect it
to the same ground. I was wondering if I could get away with a lighter
wire or thin self-adhesive copper tape for this.

Steve,

SSB radio to Tuner by ground strap _is_ the Radio's RF _and_ lightning
ground, as long as the Tuner has a good connection to sea-ground. For RF and
lightning protection, the copper connection you make between radio and tuner
is a bond, and the tuner is the connection with ground. Copper tape if 26ga
and 1" wide or better would be ideal for both RF and lightning bond
purposes. If the copper flashing is impractical for you, a soft braid
connection is also acceptable, but it should have as much surface area as
possible.
