The problem with day shapes is that the sizes are huge. The minimum sized
anchor
dayshape is about 2 feet in diameter. Boats under 20 meters are allowed
to have
proportionately smaller dayshapes, but there are no exact formulas issued
for
what that means, so anything under 2 feet is open to dispute in court.


You can get black plastic ones like balloons but thicker with an eye top and
bottom to allow you to hoist them and pin the bottom down. Flatten down to
nothing when deflated.
