My nesting dinghy that is supposed to sit on my sailboat foredeck was
an ugly shade of left over green paint and it needed repair.
So.........recalling times I have been in the fog and worried about
being run down in my white sailboat. I'll paint the dinghy the
brightest color possible.
I have now named her "Retina Burn". Fluorescent yellow/green on her
outside and fluorescent orange on the inside, it is impossible to not
see her. Unfortunately, I neglected whether the people around me in
the marina will object.

You're better off to buy a good radar reflector or two and hoist them
to the spreaders.
