Boom Sock Modification or Rudder-Up Modification

Do you need either of these modifications?

Boom sock modification: When you slide the booms straight down the mast, the booms and your sail will stick out beyond the back end of the boat. We sew a boom sock out the back to protect your sail from the sun. (Add $).

Rudder-Up modification: If you have a kick-up rudder, we extend the cover to protect your rudder from harmful UV sunrays as well. This modification will automatically cover the end of the boom. (Add $)
