I'm not sure what's behind the tape, it was too high up the mast for me to check.
The boat has been neglected and been sitting on the hard
for at least 2 years, so there are plenty of potential trouble elsewhere on the boat (batteries are dead so can't check if the electrical system
is working, the engine
would need to be prepared before attempting to start it, sails
are old, running rigging
need replacement, etc, etc..).
I'm trying to get a fair assessment of the major expenses before deciding if it's worth making an offer (which will be subject to a survey
and sea trial)
