I posted a proposal earlier today on the VI Tennis UK Facebook group. I'm
copying it below. I'd be interested to hear your thoughts, of course.
Re tactile lines on the B1 court, I have a proposal to put forward.
Keep the centre mark quite small (extending forward no more than 30 cm from
the baseline); and no tactile doubles sidelines (i.e. the outer lines).
The reasoning is this. When I find a tactile line which I think is parallel
to the net, I immediately know it's the baseline. That's why we don't have
a tactile service line.
Similarly, when I find a line which is at right angles to the net, I want
to know straight away that it's the singles sideline. That allows me to be
as independent on the court as possible - I don't want to have to keep
asking an official whether I've found the line I think I've found.
Yes, we need a centre mark, since some players serve from there; and the
standard 4 inches (10 cm) that's used on the full sized court is probably
too small to find easily without bending down. But if it's relatively
short, we'll easily be able to tell the difference between that and the
