The wire inside the fiberglass whip has broken and is making
intermittent contact. The only thing that's inside the fiberglass is
a piece of hookup wire wrapped around a form then fiberglassed to form
a continuously loaded shortened whip. They break.

Disconnect the whip from the tuner and haul up a 40-50' piece of wire
hooked to the tuner's high voltage output with insulating line on the
outer end. Any wire will do, even a dropcord. At your dock, haul it
up your neighbor's mast or anything you can get to. Once set, try to
see if the tuner will load the longwire. This will separate the
possible whip problem from the possible tuner problem so we can
determine which of them is the true problem. Don't let the longwire
get near any metal objects. Stand it off any rigging with a boat
cushion or insulating pole if you have to. It also doesn't need to be
string tight.

If it tunes, the whip is toast. If it doesn't send the tuner to the
shop.

Lessee: 23 feet, say 7 meters is a quarter wave
so a wavelength is 28 meters.
300/28 = 10.7 MHz or a little lower....

The wire in a glass whip can break.
Checking it for resonance would eliminate this possibility.

you didn't say what the antenna is - assuming sailboat backstay -
maybe check the condition of the HT wire from the tuner to the
backstay?

The wire in the whip isn't a straight piece of wire. It's coiled
around a form to form a continuously-loaded shortened whip. The
electrical length of it is considerably longer than 23'. It'll
resonate lower than 10 Mhz somewhere......

Nope, it is just a straight piece of wire. No coils at all. Unless it
is one of the old antennas for 2 mhz only.
With a coil in them they will not work above 4 mhz. Only a small part
of the antenna would be effective on the higher frequencies.
